Low fuel pressure, i think?
My gti idles lumpy, has poor mpg and the fuel pump (i think) is noisy and on continuously. The fuel filter didn't squirt me in the face when I disconnected it (as it has done on a previous Mk1). Also when I undo the fuel filler cap there is no pressure release. There are no apparent fuel leaks. Would anyone off the top of you heads know these symptoms and the possible cause of the low fuel pressure and resulting poor running. I really want to take it abroad to drive but need it running tip top.
Cheers

Poor idle, fuelling and noisy pump make it sound suspect.
It won't necessarily be low fuel pressure so much as erratic. If you pull a fuel line off and feed it into a jug when you turn the engine over is it a continuous high powered stream? If not you don't need a gauge to know it's broken (although no they aren't expensive)

Yes the pump is noisy, like an electric buzzing sound. You say pull of the fuel line and put into a jug. Can I do this at the fuel filter before the fuel distributor metering head or do I have to remove an injector.
