Default FS: Walbro GSS 341 255lph pump, never used

Got a Walbro GSS 341 255lph fuel pump. Never used. Comes with harness for universal wiring. Was gonna sell to phillyb but his car fail continues.

Aaron was gonna buy this but got impatient and he paid too much.

$70+ship.

Okay, stupid question time. Is there a point where the pump can supply too much pressure? Is there a reason to stick with say, a 190 vs. the 255?

Just like a turbo, pressure != flow. You can most definitely overrun the stock FPRs ability to bleed off extra fuel, which will result in a rich condition all around.

the 255 is great for the returnless fuel systems (like mine)

If you have a return fuel system, this is easy to regulate via fpr and gauge. That's what I used to do on the nissans, was run 3 or 4 bar fuel pressure.

Sorry, forgot to get a pic this morning. Aaron can vouch for me though.
