when to change fuel pump?

[StangerJon]

yes I'm wondering if I would have to get a better fuel pump if I just put the psi to about 18-20? or would I be fine with the stock one? and also what size is the stock fuel pump? (lph)

ummm --- I assume you mean boost is up to 18-20

the stock fuel pump is (i believe) a 88 lph pump

when starting upgrades, a fuel pump is about the first place to start --

and remember -- the high fuel pressure 255 lph walbro pump is worth every penny!!

I've seen it make 20 hp difference on the dyno, when 2 cars were setup almost identically..

well right now there is someone by me selling a 190lph for $60. would that be a good deal? he wants to get something bigger. so it works because it was in his car.

Depends on your power goals. If you don't plan to do much more than what you've already got (aside from a few minor mods) then the 190 will be just fine.

Mods seem to be addictive --

and for $10 extra, I call it insurance. (it's worth that to keep from having to drop the tank again)

The high pressure pump is better for turbo apps because it does a much better job of keeping up with the boost (the 1 psi fuel per 1 psi of boost rule)

I also use the 255 instead of the 190 --
My thinking on this was--
in 10 years, when my 255 is old and worn, it will still be putting out 190!!
