Sorry wrong part, if u do a search of in tank fuel pumps from ac delco there are a bunch listed. many of them cover a range of vehicles.

That one is for LT1's such as in buick roadmasters. I'm sure they have other applications and brands that could be made to work as well.

if you try to search by application, it seems that they list a lot of TBI or carb setups.... but i didn't find any port injected setups in my quick search.

Looks like that one is listed for everything from 454's to 2.8's and smaller.

Be wary of fakes.. .lots of them out there.

What is the p/n on your injectors BTW?

[robertisaar]

i'm not so sure if either of those are actually walboros...

but IIRC, a PFI fuel pump is generally the same between major changes (like the tuned port 85 camaro using the same pump as a 95 3100 wouldn't surprise me one bit).

I need a fuel pump for my 96 Grand Prix SE 3100 Turbo 5-8 psi boost with 36 lb/hr injectors.

No FMU used, stock fuel pressure. Fueling increases are done through the PCM instead of fuel pressure boosting. So I don't need a high pressure pump, just high flowing.

I haven't ever had to fit a high flow pump instead of a stock pump, so please excuse my ignorance regarding.

I would like a Walbro 255 but not sure of the model needed.

This is what I had found so far. Would these pumps fit my vehicle?

Walbro GCA758-2
Walbro GSS307

If not, can anyone recommend a quality high flow fuel pump for my application?

Thanks
