PFS is proud to offer a true drop in 1000+ WHP capable LPFP for 8V Audi RS3/TTRS. We start with a factory bucket and add custom PFS fittings, hoses, and a brand new Walbro 525 (F90000285) fuel pump, fuel filter/FPR assembly, and wiring harness. All connections are Crimp/Solder/seal, we use brass M6 terminals and nuts to minimize heat build-up and corrosion, and fuel pump wiring is sized optimally.

We did extensive testing on our flow bench and chose the FPR/Filter combo that flowed the best -it turned out to be a factory VAG part. Flow numbers were as follows:

The Factory Filter/FPR in the RS3 pump flowed 480LPH (2.1GPM) at 80 psi

PFS External filter with 10 micron SS serviceable filter 480LPH (2.1GPM) at 80 psi (same as other upgrades are offering)

VAG 6.6 bar FPR/5 micron filer assembly 540LPH (2.37GPM) at 80 psi

This pump is a true drop-in meaning you pull the factory unit out, install this pump, install a simple two wire harness, and that's it! (of course, tuning changes are required to avoid CEL). The secondary pump is activated via hobbs switch, the easiest location is a 1/8" NPT thread on a throttle spacer (used for meth/etc).

We offer the pump 3 different ways -

Brand new build:

You keep your old pump, we send you a brand new PFS bucket

Core Exchange after you receive the pump:

You pay a core charge up front, we send you a brand new PFS bucket, you send your stock pump in for a core charge refund

Core Exchange before you receive the pump:

You send your stock pump in first, pay no core charge, and we send you a PFS bucket. No Extra Charge.
