Anyone rebuild a fuel distributor:82 380?
Just a quick ?. Can I rebuild my fuel distributor with a new fuel distributor valve kit offered and a new lg o- ring. It is that one item I am not very familiar with. I am also sure this is my culprit for my hard "hot" starting problem; everything else is new. Thanks!

You can reseal the fuel pressure regulator! BUT that is the only replacement parts!

yeaaa..No. Rebuilding FD'ers is for those that have the experience and test equipment. Either buy good used or get a reman...avoid Python's.

Fuel distributor rebuild?
There is a thick 'diaphghram' that seals the top of the fuel distributor from the bottom (and the intake manifold) I am not aware if that part is available. If it is, it CAN be replaced.
The distributor is a very precisely adjusted flow splitter. It accomplishes this task by keeping the PRESSURE to each injector identical to the others. EACH outlet has to flow the same amount of fuel as the others across the full range of flow rates (idle to wide open) there are spring adjustments for each cylinder that accomplish this 'balancing'. It requires very precise (and costly) equipment to adjust the fuel distribution. DO NOT ATTEMPT to adjust the fuel distribution balance. You will definitely screw it up.

Hot Start Problem.
I suspect that the problem is in the fuel return circuit.
I had the same problem in my BMW 320i. There is a spring loaded piston on the fuel distributor and there are o rings in there that get worn. This allows fuel pressure to bleed off and there is no pressure when you hit the key. It doesn't affect cold start as the cold start injector circuit provides fuel. Here's a link to a very good book. http://www.amazon.com/exec/obidos/tg/detail/-/0837603005/qid=1129734271/sr=8-1/ref=pd_bbs_1/002-3995347-5796015?v=glance&s=books&n=507846 Good luck. Mark

Do a search, somebody in this forum has made a nice thread with pictures and has repaired a fuel distributor.
I dont remember if he succeeded or not. Neither was it said where he was able to bye the repair kit. I would be very intested to know also.

Again.. thanks for the info! I am convinced that it is a return problem too. The fuel accum and pump are new. Will resealing the regulator solve the bleed-by? Or could it just be crud stopping hthe return spring from letting excess fuel return to the tank side of the fuel line. Finally, has anyone sent their unit off to be rebuilt in fla. for 325$?
