Hello I posted a message a while a go about my fueling problem, during the few weeks I have tried some of the suggestions.
The setup I have
* standard mini tank with fuel return fitted (a non enlarged fuel outlet pipe)
* Brand new Bosch fuel pump (metro turbo)
* 8mm Copper microbore fuel line
* A not that old (replaced last year/maybe 6 months) fuel pressure regulator (FPR)
* Fuel filter clear in line between the regulator and the carb
* Fuel pressure guage T'ed off after reg. before the fuel filter

My problem is that when i am sat at idle it appears that there is no fuel in the filter but the guage says there is 3.5psi. When I first drive it up to boost then pull over the additional fuel pressure encourages the air through the system and the filter will fill up. However, when i continue driving the fuel pressure will slowly die away until it reads 0psi and then it will use up the rest of the fuel in the filter.
If i link the input of the FPR to output the fuel flows though it fine, so I think that my fuel lines are free of blockage. I am thinking about buying yet another FPR as it is now one of the oldest parts of the system?
My main problem is I am seriously losing interest in my car it seems that no matter what i ghange there is always the problem.

I am tearing my hair out as I type!

Please, please HELP!

I had a problem with a diesel van in that if left over the weekend the fuel would run out of the fuel filter and back to the tank meaning it would no start untill the system was blead through .

it not quite the same but i fitted a non return valve and it solved my problems and they dont cost much so give it a go .
