WalbroF90000274 In-Tank Fuel Pump (Universal 450Lph High Pressure Version), 1 Pack

used on a low boost ls1 car and works well

I had an aeromotive 340 stealth pump and I was maxing out pump @540whp 110% injector dutycycle. 340 pump claims 600+whp but proved not to be the case in my setup. I was loosing fuel pressure pressure at high boost (23psi) only making 540whp on built h22 sleeve block GEN2 pte 6062 turbo w/ 1300ID injectors on sunoco leaded 110 fuel. I know that 1300cc injector max out around 650whp on 4cylinders, so I knew that I should not be running out of fuel at this horsepower so I change the pump first because it's much cheaper than changing out injectors. Just by changing out the fuel pump with the 450lph my injector duty cycle went down 25% after air fuel ratio got re-dial-in.

perfect part and fast shipping

Order came quickly and was priced better than anyone else.

It came wrapped in a plastic bag. Not a walbro box like in the pic. It doesn’t say walbro ok the actual pump 🤔

Ordered pump at night and was driving again the next day.

The media could not be loaded. Pump works when ignition is cycled but no fuel output. I’m very disappointed. I took a chance and now I’m down and out. Please QC pump before selling

It worked great and arrived on time
