Is that a condition for the sale?

I'm thinking anybody that wants to buy your car better put a deposit on it now. After you get it back together and drive it, with the bugs worked out, you may not want to sell it.

Tempting, but not likely. Just into too many things right now, and it has been a shame that I got burnt out on it. It is kinda cool to be working on it again tho

At Pontiac Nationals in 2006, after the rebuild, I pulled the 13.4 1/4 mile on bad detonation, which resulted in the rod bearings loosing their crush. This resulted in the reaming of the #5 rod journal removing ~.006" of material and bending the crank ~.009" . We magnafluxed the crank checking for cracks, bent back in to spec, magnafluxed again, then turned the crank removing .010 from all the journals. (work was performed by WRP). Now the crank is in, and pistons and rods are about to go in with oversize Clevite bearings. All of this simply because I plumbed the Walbro fuel pump and assumed the little port on the pump was a high pressure line. It is actually a pressure relief. So it was not feeding the venturi puump drawing fuel into the pump assembly. So the 65# mototron injectors was starving the fuel pump... I pretty much ran out of fuel on the track, leading to BANG, BANG, BANG!

A stock engine would have yielded a few popped pistons

Hey dude , hmm what was the problem with the Walbro fuelpump? Because hmm did the same as you did with mine.

You need the fuel line tap with the small nipple to feed the venturi pump. On the Walbro, the small nipple on the top of the pump is a pressure release, not a high pressure line. Install the tap in the middle of the main fuel line from the pump to the pump assembly (where the corrugated hose is now) using the 5/16" fuel line that comes with the nipple. This is in the 3800 specific Walbro 255lph Fuel Pump kit by ZZP. This was updated in my gallery How-To:

Below is a pic of the nipple, clamps, and 5/16" fuel line:

Hmm hey any pics of installing this?

[TurboAleroGT40]

Hmm and one more question, what do you do, with the small opening on the pump? because when I bought mine it was closed, and we opened it and installed the small nipple from the stoch pump.

[tejohnson]

I would use a piece of tubing (attach to the nipple you installed on the walbro) and redirect the open end to the bottom of the assembly. That way if it is functional, and it is a pressure relief, it is simply pumping the blow off into the bottom of the pump assembly. Make sense?

Check this out they didn't use the T fitting. They just installed it the way I installed it

Okies, hmm one question, what did you do with the fitting that you put on the walbro pump the brass thing that U and me installed on the walbro pump? Do you need to close it, remove it,.....???
