    Hey! I went through FAQ and used the search button and didnt come up with an answer so...

    I took the HJ47 to a Fathers Day car show yesterday. Ran great there then I couldn't start it (in front of 300 people.) It stalls when I push the clutch in. Starting either fires right up or the starter has to whirl for a while before the engine idles. Its sluggish now and fights to get up to speed.

    Feels like fuel isn't getting there. I replaced the fuel filters and the air filter over the winter. I can't get the sedimenter open to drain it as the bolt is stripped. Wondering if thats clogged and is creating some sort of vacuum issue? There is no smoke at all but maybe the diaphragm needs replacing?

    I replaced the head and most everything under the hood this winter. It ran great until yesterday.

    Any ideas? No leaks on the injector pump or primer plus fuel lines are clean.

    Hi 40flipper,

    It could be air in the fuel system, try bleeding the fuel filter and then the IP, do it a couple
    Of times and see does it help. There could be a pin hole somewhere and it is drawing in air when it is sitting for a while.

    I replaced the fuel filters but I'll probably check them again tomorrow

    It certainly sounds like a fuel restriction or sucking air.. its a process of elimination starting with the things you last touched first.. if you have the dual filters then verifying O Rings etc.

    The factory sedimenter should be deleted and replaced with one with a clear sight bowl.. in the short term it can just be bypassed by taking the two soft hoses of it and joining them together with a bit of bundy tube and some hose clamps.

    The symptoms your describing do not point towards the diaphragm at all.

    A length of clear hose at the pump inlet will help diagnose if you're struggling.. if the system primes up and runs OK for a while then gets progressively worse and stops then thats a good indication its a fuel restriction or air leak.

    The sedimenter can have a pinhole leak, easy to clean when you remove the top:

    Most time when people have starting issues it is a pinhole leak, invisible but can be in hard and soft line so not easy to find.

    there is also a mesh filter before the fuel pump but mostly never clogged there:

    Hi,

    I read a post by mud member lostmarbles, and to find a small leak he had in the fuel system he pressurised his fuel tank with compressed air and he was able to locate a leak on one of the metal lines.

    If the bolt is stripped on the water trap time to bypass with some hose to rule this out of pulling air into the system.

    I just ordered a new aftermarket fuel separator. I'll leave the old one for aesthetics. Also ordered new fuel filters. That should do it I hope. Will know next week. Thanks for the help and I'll keep the thread updated
