Excellent upgrade fuel pump, install could be better
Deathryuu 1 month ago
Bought this to support upgraded 1000cc fuel injectors on an 07 Subaru WRX. The install could have been easier when it came to swapping in this pump. The fuel pump housing was slightly longer than OEM and so was the outlet, so I had to trim the hose connecting the pump to the car's housing, bend the bottom of the car's housing so that the support piece for the pump would allow the pump to fit. After finally fitting the pump into the car's housing, it was a very very tight fit, with the outlet on the pump right up against the inlet on the car's housing, as well as the support piece for the pump being bent slightly downward to accomodate the pump. The pump could not have been pushed up any further without cutting the inlet on the car's housing which I didn't have time to do. It seems to be working fine the way it is so far, though. The pump sounds very good. People complain about them being very loud, but the Subarus seem to have a fuel pump controller that allows the pump to run much lower power and be much quieter during normal driving, so the only time I ever hear it is when it primes as I start the car up. When you get on the throttle, the exhaust quickly drowns the sound of this pump and I still don't even hear it.

    Support 1000cc injectors. Blouch 20g ball bearing turbo. Front mount . 3 inch perrin inlet. Turbo back header and upipe. Will this pump be enough to suppor these mods


    • A: Yes, this pump would support your setup as long as you were running pump fuel. If you plan to run E85, I would recommend a 300lph fuel pump.
