So like I said, it may not need to be done but you could weld a pass through aluminum tube in the intake manifold to line up with the puff limiter for a cable to run through and attach like the Attitude which would allow you to turn it from in cab. Not sure how bad the tube in the intake...

Nate I should have added, I have not had the pleasure of running a pump with a puff limiter yet so maybe once you get the housing dialed in, the boost reference adjustability is enough. You would know better, I'm just always brain storming one way or the other, LOL.

Thanks Nate, that's cool stuff. I'm sure you've thought about this but I was trying to figure out how to adjust the Puff Limiter housing with a cable and knob sorta like the P pump Attitude Performance adjuster but I can't figure out how with the GM intake manifold so close to it. That with the...

Man I wished I had a core pump I could take apart just to better understand the workings.

Nate do you have any postings showing your Tahoe setup? I thought I had read most of your threads but maybe I missed something somewhere.

I guess I'm confused on the workings between the transfer pump timing and the advance servo timing, I see how the advance servo moves the cam ring when the throttle is opened but not sure on the transfer pump. So is transfer pump timing controlled by RPMs or fuel pressure? Sorry for the 100...

Hey I just thought I would bring this thread back to life since I'm dead in the water with the Burb for now. So can anyone tell me why Wes @ CDD is using an adjustable boost, boost referenced fuel pressure regulator on his DB2 pumps? I would ask him directly but I have been unable to contact...

Also when I told Mel I was building a fancy 25-30 PSI boost referenced fuel system he said I was wasting my time and the Walbro pump was more than enough. (quote unquote)

Are you looking at the first invoice I posted which is the second pump? It says it tested at half engine speed the first pump test results read different.

No, I'm running a Walbro that's puts out around 14psi.

Here is the .350 pump Conastoga did... note the different injector pressures, my present injectors were done by them popped @2250 psi.

I was just looking at the results, its putting out 150 CCs at 400 engine RPMs correct? It's fuel stacking like a bitch! Am I wrong?

Here you go

So I messed with the pump a little just know, when I went to pull the pin out of the advance rocker lever I discovered that there was no C clip retainer on one end, I doubt it fell off so it was probably left off. So after removal of the lever I pulled the servo advance plunger, then I took a...

I guess getting parts machined out of stronger metals like titanium or something would be too expensive huh? And at that point maybe machining a different pump mounting configuration and using a better pump would be cheaper, not cheap but maybe cheaper, just brain storming. Is there a 8 cylinder...

So if I get that apart the servo advance valve should just fall out if I turn the pump on its side if it's not stuck correct? Or do I need to take a magnet or something to get it out? see diagram

Another thing I'm trying to understand is when you tighten the screw on the leaf spring lets say a 1/4 turn how does that increase fuel output? Is that the screw that you turn? I'm not intending to do it on this pump I'm just trying to learn about the workings of these pumps. I am thinking of...

Do I take the bottom plug out to check the advance servo? Regarding the fuel rate of the .350 pump, this is why I've been chasing more fuel output.

I know I've posted it before and it doesn't matter now but here is the flow specs from the Pennisuler .350 pump

Here's a video...
