Hey Guys, What is the best suited bosch fuel pump for a V6 STI.

Depends on how much fuel you want.

Well i have some mods and will be fitting a power fc. I want something that will be more than sufficient.

some mods....so we talking 900HP, or an air filter and exhaust?

Again, not a very clear question

Walbro GSS341 or 342 is the best bolt-in pump...no mods required.

Bosch 044

That's what I run in tank, be sure to remove the check valve from the pump outlet.
Allow about a hour to fit it if you do it yourself (it's not a direct fit).

Walbro's are the easy option as they're nearly "drop in" units.

worth noting that 044's are noisy, where as walbro's are nearly silent.

my 044 is noisy as, can hear it clear as day off the freeway walls, i would recomend the bosch, i think they are cheaper aswell but may be wrong...

i think it goes for all bosch fuel pump as my mate's R33 also has one and it is resonably loud seating if you at the back

mod list for V6 STI- air filter, exhaust, silicone intake, up pipe, powerfc and maybe a few other small improvements. Im not going too crazy on the mods so something suited to those mods please. Not too worried about the noise as the car will be plenty noisy anyway.

i think my wrx has had a fuel pump upgrade that i was not aware of on the purchase, quite occasionally i can hear it during idle... is this normal for a stockie?

Reflex, go the walbro 341/342. they are a 500 hp fuel pump, and are a direct swap for a DIY install. and about $150 from ebay.

just remember to unplug your battery when playing inside the fuel tank
