Fuel pump DELPHI or WALBRO

I got a Delphi pump from autozone for like $120 and it’s been fine for 3+ years.

Walbro 535 LPFP fitted in the stock bucket with the factory venturi system.

Walbro 400lph is what I ended up going with on my 76mm turbo car, with 60# injectors, was perfect for over 25k miles at 15psi making 750whp. I installed the Walbro in the stock bucket, modded.

I bought a Delphi from RockAuto. I primed it 3X and car fired right up no issues even years later. No check engine light, no hicckups nada.

I got the Delphi rock auto one and has been working fine for the past 3 years

Mine wouldn't start back in 2020, and I bought a Delphi pump from AutoZone and replaced that, keeping the bucket, float arm, etc. that I already had in there. More than 40,000mi later, I still have no problems.

Plug & play reliable one I bought 220$ Delphi from Rockauto

I primed it, 2X key on Ignition, fired right up.

since the original pump (aged) is hardly safe over 200whp imo; esp with increased rail pressure.

I personally wish I went with a non walboro option for what it's worth. Just annoying loud on low tank.

Something happened to Delphi's quality the last couple of years. Used to use them a lot, but the last few pumps I've gotten from them have been complete shit.
