fuel pump options

[Texas gst]

I'm wanting to get a 190 or maybe 255 fuel pump. I was wondering if these are stock on any cars? What I'm curious for, is that I work for a national repair facility so I can get great deals on parts from Advance, O'reilly's, Autozone, etc. Is there a vehicle that I can get one for that is the same? Easily stated, can I get a fuel pump for a 99 mustang gt (or whatever) that is the same?

IDK if they come stock in any car. Maybe the mustangs, but wally fuel pumps are relativity cheap in the fuel pump world. 99 bucks for a 255 with install kit is pretty good.

An alternative is using either the evo 8-9 fuel pump or utilizing a Supra TT fuel pump. Both have been used by people on here with their DSMs.

goodluck

I don't think that Walbro's came stock on any cars. Your better of getting a pump made for your car. I do believe that the Evo 8 pumps may fit on the GST.

if you really are short on money you can also rewire your fuel pump to make it push out a little more but best bet is to just go ahead and spend the money on a 255.

Will I HAVE to have a fpr with the 255? I'm about to put on an EvoIII in about a week, and down the road I am going to get 650-660 injectors. That's why I was leaning towards a 190, but if a fpr is not needed for this setup, than I guess I should just go with the 255. I think I'll do the rewire when I put the turbo on, just to be safe for now. I'm only going to run about 14 psi, as I have read a lot that it will be safe with my stock fuel system.

anything more than a wally 190 you will need a FPR

if you are running some evo injectors you might need a fuel/air controller.

14 psi should be fine with the stock fuel pump and FPR.

Will I HAVE to have a fpr with the 255?

Do you have to? No. Is it recommended? Yes. Having a 255 lph pump with the stock fuel pressure regulator will cause you to run rich at idle and low speed cruising but at WOT it won't really matter.

Hope this helps!

I am running a 255 with out a FPR, runs fine. As stated above it does run a little rich at an idle.

3000GT VR-4's and turbo Stealths had a 180lph Denso pump. It was a decent, cheap upgrade back in the day.
