I need a fuel pump!

[s10xtremist]

Can I have too much volume/pressure, being I have a (factory) fuel pressure regulator? The only fuel pump I can find are Walbro's with either 190gph or 255gph. Which do I need for 6 lbs. of boost on an '02 4.3? I need to order one ASAP and have it in before Thursdsay.

I'm gonna get the 255. Stock lines will handle it fine. For me what it needs to handle is the increased pressure.

I'd get it if I were you.

Thanks. I'll order it.

O.....k. I can't even find a part number for the pump I need. I've been Googling for a long time and noboby has a Walbro pump for my application. I know they make one. Is it the same as the one for a 96-99 Vortech 5.7? Walbro's site doesn't even have anything- mostly just a bunch of weedeater carburetors. Somebody please give me a part number or something!
