Hi all, looking for some advice regarding the fuel filter on my AVF 1.9 tdi.
I have been running a mix of bio fuel for the last few months and had bypassed the original filter by using an inline filter on the supply and return pipes.
Yesterday I replaced the factory filter and the car was running on my driveway for about 10 mins then it just cut out.. When I removed the pipe that supplies the tandem pump I was squirted with fuel.
I've never had problem with pressure building up in the filter before.
I connected the hose back onto the filter and the car started again, then after 10 mins of idling it cut out again with the same pressure in the filter..
I tried another factory filter and it done the same.
I've went back to the 2 inline filters and all is well.
Anyone any ideas what might be wrong.
