255LPH High Performance Electric Fuel Pump Replace Walbro GSS340 with Installation Kits

Got this to replace a 6 month old 255 genuine walbro that died on me. TO my surprise, this seems to work better. It seems to flow a little less, but it is more consistent. And quieter?? We'll see how it holds up.1986 Nissan 300zx, VG30E, GT3071R turbo, 450cc inj. @ 50psi. Nistune multiplier set to 300, a little higher than I had the walbro at even with a lower base fuel pressure of 44psi

I have 1990 Caprice with bad idling specialty after warming up hesitation, reving up suddenly and sometimes shuts off. After replacing Throttle Position Sensor, MAP sensor, Air control sensor, cleaning the whole throttle body, replace fuel filter. It had come to last thing The fuel pump was weak. This pump seems good quality and quite it got what I need to replace the old one except I had to do wiring as the plug wasn’t the same. I recommend it for the value and hopefully it’ll last for long time. Fits 1990 Caprice.

I replaced the OEM pump with this 255L/hr pump and was able to start my '88 Fiero GT for the first time in 15 years. Tuned it up and the car was running great. About two weeks later, the engine began to stall on acceleration and then wouldn't start at all. Replaced it with a Kemso 355L/hr unit and now it's got plenty of fuel pressure and running better than ever.You get what you pay for - this pump was cheap! Spend the extra money and get an ACDelco/Delphi fuel pump for your GM vehicle.

Had to modify brackets to fit into stock location, pump works fine but was kinda hard to get to fit right, Otherwise works fine for application , not noisy or any pressure fluctuations.Good value for the money!

worth the money thanks
