Fuel leak back test specifications

Postby Paulscarbs » Mon Jun 22, 2020 12:02 pm

I’m trying to undertake the fuel leak back test.

Does anybody here have the correct specifications in terms of timings, engine state and fuel return expected?

Please post below.

Might help if you specify what engine and year of van your working on?

For Mk7 Euro4 General consensus from memory is 4mins at idle 20-40ml, but happy to be corrected.

Indeed it would.

2.4 RWD from 2009.

Can't find reference to ANY leak back tests though.

If your using a cheap test kit then calibrate your bottles first, makes life a lot easier. Image
