Petrol heater feed taken from fuel return pipe?

[mshaw1980]

Hello

Has anyone ever used the fuel return pipe rather than the fuel outlet pipe to tee off the feed for their petrol heater? The reason I ask is my van keeps killing electric fuel pumps (bosch) and I have a new fuel injection tank so wondered if cavitation of the fuel caused by the heater t-piece is the problem?

Did you ever check that the fuel pressure reg was ok, and not causing excess pressure? As obg said, the T wouldnt cause any issues (hes overseen a lot of installs)

You know I had completely forgot about that response, duh. Another tool purchase needed then ie a fuel pressure tester

I'd have a read on a Subaru forum about how to test the pressure best. My guage I'm sure only cost a few quid, then attach a length of hose onto it. Just make sure you get the right scale to measure it with
