Thanks for all the ideas. I have previously installed a pre lift pump filter, and removed the in tank sock. Also have a pressure gauge after the engine filter, but I will have to look into adding something to indicate a plugged lift pump filter. It seems though that the pickup tube in the tank...

Thanks so much for the input. Turns out that now the dealer is saying its a LB7.... How do you know for sure which it is, without having to take some sales persons word for it?

I have a friend who is looking at an 04 (pretty sure he said it was an LLY). It has a little over 200,000 on it, no record of the head gaskets being replaced yet. He heard that these engines are known for having the head gasket go about this mileage, and was wondering if he should plan on...

So the transmission in the tahoe has jumped out of gear 3-4 times now over the last month or so. It has a USShift Quick 4 controller and has not set any trouble codes. So far it has been too rare of an occurrence for me to catch it with my laptop plugged in so I can see what it is doing. With my...

So my first trouble shooting step was to open the fuel cap. (no suction) Next I opened the bleed valve at the engine and relieved a vacuum.................. There was also another vacuum on the inlet to the Walbro which I mistakenly took to mean that the problem was in the pump, but I see now...

Ok thanks for the info........... since it has happened a couple times, I had convinced myself that it was the pump, but it looks like I need to do some more trouble shooting. Thanks again.

When it was working well, the Walbro would hold 8 pretty well and would only dip down to 6 on acceleration.

If my memory serves though it seems that the stock one only ever held about 4 PSI and would drop to 1-2 on acceleration. As for the Walbro, I think I have heard that they do not free flow when they fail. That was a down side of switching to that type of pump, although when I bought it I...

Well my lift pump on my truck is starting to go out. When it fails it still makes noise like it is pumping but it does not even allow the IP to suck fuel from the tank. I made it home by taking the fuel line loose and relieving the suction that the IP had put on the system, whacking the LP like...

I personally really like the original light brown/gold color. That is the color my tahoe is...(maybe I am lazy but I like the fact that dirt does not really stand out on that color so I don't have to wash it as often. So if it was me I would repaint the hood and roof to the original...

..... an ejection seat.

Glad to hear!

If the tach gauge is like the fuel gauge, in the same cluster then the needle is just a press fit on the shaft. You can pull it off and then push it back on clocked to the correct position.

If I understand correctly...... when the truck is running, then no fuel comes out the drain valve? This makes me wonder about the fuel lift pump. There should be a low pressure fuel pump (probably mounted to the front passenger side of the engine) that supplies fuel to the high pressure...

X2 on the newer controls going bad on the later models... I have a 94 and a 96. I just put an aftermarket radio in my 94 so I could play CD's and have a USB input.... The thing I really don't like about that is how far over I have to reach to change the volume or tune it. In the later model dash...

I have been able to get free wiring diagrams from this site...... http://www.bbbind.com/tsb-and-wiring-diagrams-login/

Very nice.... it did not make me an engineer......... but at least I now completely understand the basic difference between HP and Torque......... and what gives an engine each.

The biggest reason to keep the PMD mounted tight is that it needs to transfer heat to keep from frying itself (it gets very hot if left hanging in free air) so you want it mounted tightly to a good heat sink.

But I agree with your preference........

I think the steering column would prove to be problematic.....
