Fuel pump WALBRO or OEM Volkswagen

I used a Wallbro, have had very good luck with it.

I've never had issues with genuine walbro pumps, took me well over 500hp reliably on several vehicles.

Got my Walbro Hellcat 525LPH in last night, there's definitely been a noticeable change in how the car behaves. On the FPR side, I had it set to 3bar with my stock pump in, the 525 instantly shot it to over 60psi with the same settings.

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.

Easier said than done to install the B6 fuel pump into the corrado tank. The pump fits but the top flange's outer edge needs to be ground to fit the locking collar. Then the inside diameter of the locking collar has to be opened up.

my OE fuel pump is tired, needs to be replaced soon but its check valve is still holding pressure.

I had similar problem, and have read of others when fuel is below 1/3. I had just changed sticking fuel pump with new and developed the problem. I thought it might be fuel level calibration, but it took another new pump to solve it for me.

My wife's has had electronic gremlins since we got it in '21 (it's a MY22).

-Passenger seat heating mat and occupancy sensor was causing codes and had to be replaced (1 week in shop).

-In-tank fuel pump has been replaced twice on recall.

-Some other recall thing that caused it to randomly go into limp mode (1 week in shop).

I have a high flow Walbro unit that I regret installing because of the constant noise it makes. Unless you need to support super high HP numbers with a modded engine, go with an OEM fuel pump. I will just have to live with my loud pump because it is way too much work to drop that tank again!
