Audi EA825 4.0T V8 Spool Low Pressure Fuel System Upgrade

This low pressure fuel system upgrade for the EA825 4.0T V8 uses the Torqbyte PM5 brushless pump controller to raise the factory pump's flow by over 60%.

Why you need it

Stage 3 and Stage 4 EA825 setups making 800 to 1,200 hp need more low side fuel than the factory pump control module allows. The PM5 replaces the factory J538 module, keeps the OEM pump and basket, boosts pump voltage up to 24V and supplies up to 40A, while the ECU stays in full closed-loop control of fuel pressure and no trouble codes are set.

Good to know

Recommended for Stage 3 and Stage 4 setups making 800 to 1,200 hp. The unit is not sealed and must be mounted inside the cabin, ideally on a large metal surface for cooling, with a dual fused 40A battery connection and solid chassis ground. A second PM5 can be added as a slave for dual pumps. Professional installation is recommended.
