What did you do with your GMT400 today...or yesterday....

With a hydroboost in the system the orifice size should be a larger size for added flow and set for a line pressure around 1200-1400 psi max. I had this issue with mine a while back finding that the one I had was the wrong one plus ordering a new pump came with the smaller size. I ended up doing a load of research finding out how to attempt to fix it. ended up drilling out the orifice to iirc a 11/32. Don't quote me on that size, I will have to do some digging around to find where I got the info. these saginaw pumps are rated for 1 - 3 gpm if im not mistaken, the size orifice is what sets the flow rate. pressure is adjusted my the valve and spring, but you shouldn't have to mess with that.

I appreciate the heads up on that.It could save me a load of grief in the long run.I might attempt tomorrow morning in getting pump and steering box off.I also have a new Hayden fan clutch to go on it as well since I’m taking the fan shroud,etc off.I was going to get the 4 bolt fan clutch and duramax upgraded fan but I said the heck with it and just buy the 6 bolt fan clutch the 96 trucks came with.I don’t tow or haul anything with it.It’s just basically a coffee run truck and pick up a few things here and there,etc.
 

Cooked well done by Tesla ^^^^
Like a van hitting a tree, driver dies in fire. Tesla does not make vans...
The guy that hit a house and burned up in that car. On and on.
So cooked well done by gas/diesel vehicles
If you wan the links so I can prove there are way more trapped and burning to death in gas/ diesels than electric- i will post the links. But faster is if you search burned car crash and while hunting through the dozens of gas and several diesels, you find an occasional electric.

It is simply silly to compare without looking into it- so pull up the first 100 and see how many are electric. Hint, the numbers are available through insurance groups. As Elon pointed out it is almost 4,000 to 1.

yeah the gm was piece of junk electric. So was a pinto. Going to the worst one ever doesn’t show the normal. It is the abnormal.

there is no way I would tell anyone to get a gm electric in the next 5 years. Tesla is what I said. I didn’t randomly pick it, and am not a guy to think electric is better than gas or diesel in every use- thats dumb. But acting like all ev is junk, dangerous, or non functional is like those who said adding the foreword pass to football would end the game within 3 years. Someone who is so partial to one point of view they can’t look at it without skewed outcomes before they even research.

Natural gas power vehicles- many folks did diy compressors to use the cheap natural gas at their home, and boom goes the homestead. That doesn’t mean natural gas vehicles are all horrible, it means dumb people shouldn’t mess with dangerous items.

Gm has horrible status on safety from every single arena they stepped into. Thinking they would suddenly be amazing at a technology they fought more than any major manufacture except for honda- who is usually the last to adapt to tech into average cars- should be a warning to anyone. Caveat emptor- do homework before spending tens of thousands or suffer the loss.

I agree ev is not the way to go for most uses still. But either y’all better pony up and start killing people or get used to electric because they are shoving it down your throat innthe name of save the planet (which I don’t agree is correct btw)- I don’t buy the dino-source concept, I don’t buy the man made temp rise. But i can see the positives of SOME of the rigs.

You do realize that EVs account for less than 1% of the vehicles on the road and about 2% of new vehicle sales, so Elon’s claims of 4,000 to 1 are meaningless.

There is use for EVs as commute cars, grocery haulers, etc. insurance rates are sky high on Teslas because they are near impossible to repair after a crash. They say they don’t have maintenance like oil changes, coolant hoses and belts to replace, etc. But really, $20’coolant hose at 150K miles? $50 oil change every 10K miles? That’s savings? LOL
 
Yes the insurance rates are sky high. But that is a cost of the repairs- not the injuries to the people. Again, I said if I was rich... which I am not (I’m Will! Haha). Having to watch money to close means it won’t happen. But strictly for the safety factor- Tesla.
I would still have my Hummer, and 43 Willy’s- a couple of rigs not exactly known for safety.
But my whole thing is based on my family being safe.
If I could afford to buy 4 cars for $70,000 each- a couple grand a year more would not be the concern. Talking about dreaming of having over a quarter million - whats the diff of calling it 300 thousand since its all pretend anyways. Haha.

Not that would have been nice to know awhile back.... When I changed gear box and power steering pump..about same time I changed hydro boost.. wonder if I got the right ones in there...lol

one way to tell is if you have somewhat stiff steering or the steering gets jerky or acts like manual steering when pressing the brake pedal. but these symptoms can also indicate other issues as well. Like a weak pump or blockage in the system somewhere else, so it's not a tried and true testing method. iirc when I did my research I found most of my info on the jeep forums where others were trying to install hydroboosters on their jeeps along with having steering assist cylinders. they wanted to get the most flow possible from the pump having three components running off a single pump.
 
Dbrannon,

I have the old reman off from rockauto so I took a couple pictures of the new Napa pump in the same area so does this look right to you?Thanks for your help by the way👍

I don't know much on the electronics for the variable steering, but from the photos the orifice in the old pump looks to be larger. get you a dril bit and use the but end to verify, use whichever is the larger without modifying anything. a 1" socket will unscrew them from the pumps. if using the old orifice as you are unscrewing it, there is a spring behind it. it's not a strong spring, but if not expecting it, it can shoot out and fly a few feet and surprise you plus get lost. clean up the fitting / orifice well and lube the oring before installing. might even swap in the oring from the new one for good measure. use the spring and pressure valve that came with the new pump as it was already tested with those installed. last thing you want to do is use an unknown possibly weaker spring or a pressure valve that might have debris stuck in it which could possibly destroy a replacement pump. you can however keep the old spring and valve when you return the old pump in for a core just in case you want to do any pressure modifications later on.

Thanks very much 👍.I’ll definitely get back to this in a few days as I need to get another pitman arm anyway.That too was sloppy this morning when I got the steering box off.I think it’ll be much better when the replacement box and pitman arm is back in place.I’m amazed the pitman was also bad.I greased it a few times since it was installed but it didn’t last long at all.

The truck might have 6000KM on it since I went through it back in 2014 so it hasn’t had much usage.I replaced everything up front except for the steering box.Has a brand new genuine GM 6.2 660 short block I picked up from eBay back in 2010 or 2011.The guy had three brand new 6.2 engines on pallets in Wisconsin.It’s all equipped with a new DS4 from kr_services on eBay.
 
Actually This truck never had that wiring connector but I scrapped down a 97 gmc that had that feature on the pump when I removed it.
Yeah, You dont want that feature. It can be eliminated. There are kits available and, I think that the units manufactured before that, the fitting and hose can be salvaged and installed onto the VOV pumps.
 
I siphoned 25 gallons of diesel from my son’s Suburban, still 17 gallons more to go so I can drop the tank to replace then fuel hose. All of it went through a funnel filter.
Oh my goodness. One bright side to it, You found the problem, I’m guessing and, it surely must be a lot warmer there than here. Shows -12 with a 3 MPH wind and says the feel is -22.

Suspect I found the problem. Never know with the fight back 6.5.

Just got the news that they delayed the return to office to at least February 1st. So I am probably headed back up next weekend.

so, EV's seem to be all the rage with the radical environmental extremist crowd. Earlier today I got a link to a group that is promoting EV's for inner city neighborhoods under the falsehood that these neighborhoods would benefit from less tail pipe emissions. Here's my response.

inner cities typically have large apartment like complexes and people park on the street, anywhere they can find a parking space. I'd like to hear an EV fanatic explain how the batteries will be charged in these types of neighborhoods. I expect to get an answer like, 'Well, the government (tax payers) will have to build charging stations on all of the inner city streets so they can be charged at no cost to the owner.' Of course, the liberals who promote EV's want the tax payers to pay for the charging networks to be built throughout America while forgetting it was capitalism and private companies that found oil, refined it into gas and diesel fuels, built the pipeline systems, the refiners, the gas stations and have supplied them with the gas and diesel year round for the past 100 or so years. The EV liberal crowd is so stupid.
 
I picked up some 1/4” npt T fittings from rockauto among other fittings for 1/4” fuel hose to slide over when I’m done and I also picked up two small liquid filled fuel pressure gauges from Amazon so I can monitor fuel pressure under the hood on both my 96 GM trucks.Its nice to view fuel pressure to keep an eye on things.
 
Finally got around to putting on the camper shell back on my truck today, it's not a perfect fit as it hangs over the bed rails by about 1-1/2" on each side, but for scoreing it from a junk yard for $35 im not complaining lol. pulled the center cab tail light out and wired in some leads to the cargo lights (bulbs were burned) so I can have the dome light work inside the camper. I discovered that the cargo lights only work when the switch is on and the door is open. as soon as I shut the drivers door, the cargo lights go off. I was hoping to have the switch work the dome in the camper for things like tailgating and when I needed light to see working on something out of the back. Might end up running a separate power wire from the fuse box to the bed for that unless I can figure out how to rewire the cargo light switch.
