Fuel meter pressure - Lack of it

[kraM]

Hi
I have an '81 Gti.  Unfortuantly it developed a noise, so I brought a cheep engine as a quick fix, whiles I get mine sorted.  I had it standing for a about 6 weeks before I swapped the engine.  Just as I fired it up to bring it into the workshops, it wouldn't, then it would.  I have spent ages since installing the new engine wondering what I have done wrong, I have now traced it down to the fueling of the car.

I have fuel pressure at the fuel filter, at the 5th injector and the return from the warm up regulator, but from the injectors, a girly dribble.  I disconected the injector lines from the fuel distruibtor and (with fire extinguisher in hand) cranked it, nothing, well maybe a small dribble.

I removed the air box, then the metering head, cleaned the air flow flap linkage, cleaned out the metering head with compressed air (I didn't take it apart)
If I pushed the plunger up the air from the fuel intake side came out faster through the injector out lets, but slowley.

So have I got a knackerd metering head, or maybe a warm up regulator (doubtfull as I have swapped it with a known good). 

Please help, as on wednesday night I need it to go to the 'no rice meet'  (the first public showing of it and the ba*tard develops a fault)

Any ideas would be greatly recieved, also, where to go in the Reading/Maidenhead area to get bits/get it repaired.

Thank you

a frustrated

sounds like the metering head is clogged up with rust, whats the filler neck like?  Also check out the inline filter in the fuel pump.  Some have a little mesh screen on the tank sode of the pump, clean this out

I have a complete metering head & lines from a running MK1, but you shoudl check there is no rust in the system before you buy it otherwise iyou could clog up the replacement!
