Title: Low pressure fuel pump pressure?
Post by: murph81 on November 19, 2013, 06:53:37 pm

I am fitting a BWJ TFSI engine in my Mk1 Golf Gti and just want to make sure that the standard pump is up to the task.

I need to know what kind of pressure the LPFP makes?

Cheers,

Adam

You should see 5bar at start up dropping to around 4+ bar at upper rpm.
Also make sure you use the correct 6.6 bar pressure release valve fuel filter.

Thanks for the reply, I have an adjustable fuel pressure regulator and I have a gauge on the way so I can set it up and monitor it.

Would you still recommend that fuel filter, I have a fuel filter fitted, just not that type.
