I have a customer with a 2004 gto with a procharger, cam and a fast intake. It had a msd boost-a-pump that had failed and they really weren't happy with the set up. We tried an aftermarket pump I believe it was a 340lph in the stock fuel module. When he went to the dyno the car keeps running out of fuel pressure. We called the company where the pump cam from and they said they were having problems with that pump and wouldn't send us another one but would refund his money. I looked at racetronix and aeromotive and they don't offer any thing for these cars. I was wondering what some of you boosted guys out there are doing for a fuel pump in these cars?

DW fuel pumps.

I'm running the LPE fuel pump only and have had no issues.

My A/F was just starting to lean out around 6300 RPM. As a result, I had the limiter set at 6400 and shift at 6300. I'm making 501 to the rear wheels with that fuel pump and 60lb/hr and injectors. A Kenne Bell Boost-a-Pump would definitely help and I will soon be purchasing one for the added insurance and then also raising the limiter back up.

Walbro is all I've ever used and hasn't let me down yet. Maybe one of the sponsors here can chime in for you.

DW pumps drop right in the stock fuel bucket where LPE needs to modified. Hit up Kollar Racing and they have everythign on their site and will get one to you asap. I'm running e85 through mine and runs nice with no issues so far.

DW 65C here as well and I did a small write up too ! I would also suggest poking some holes in the basket. I mention all of this in my write-up seen here:

Lonnies Double Pumper Kit. I have one on my Procharged LS1 and it runs great.

+1 on the Lonnie's kit, that's what I run & have no problem. I'm thinking about switching to a Proxses Tuning kit. He has a killer double intank pump setup, billet hat & it uses the Deucthwerks pumps! They're not on his site, so just give him a call.
