  1. Well hello again everyone, it's been quite some time. The mechanic has FINALLY gotten back to me with some news.

    They believe they've got it working and the issue was simply a blocked carb! Which does make sense as i was having issues in a previous thread in which i believed there to be a vaccum leak or some kind of air intake related issue. He said he'll call me again tomorrow with more news. He did say on the phone that he would pay for the wiring loom so that seems ok...hopefully the end bill isn't too high.

    It's a shame i broke down on the roadside and had recovery take it to the garage. If it was still at home i imagine we all would've reached the conclusion that it was the carb by now.

    Anyway will keep posted here if needs be but if not, I can finally put this mammoth thread to bed.

    The only sad news is that i now have to sell the car as soon as i get it back as i'm away for 6 months and have no decent storage. Wish i had more time with it over summer but such is life!

  2. Latest update. Finally heard back from the mechanic.

    They set the car on fire. Yep. Not kidding. They said they were trying to start it and the wiring loom caught on fire and melted some of the bulkhead, now i have to get an electrician to redo all of the wiring costing £450. They said they are willing to split the cost of that with me...honestly don't know what to think or do. I bet this is a new problem as well and it wont even fix the original issue...

  3. The pump still has the 6mm pipes with olives, they’re just running in to the rubber tubes, but yeah that seems to be the issue. I’ve popped it out and in a few times, and the fact that I can operate the manual pump when it’s fitted probably implies that it’s not fitted correctly. I’ll take a look with an electric pump and then if the problem persists then it must be something else.

    I have tried to stay 'Out' of this one, however found that impossible so:-

    It is very easy to get either pump on the wrong side of the cam and it will not pump if fitted wrongly.

    The short lever version fits on the outer side of the cam. The long one goes behind and needs the spacer.

    I have the glass bowl one and can unassemble the top in situ by removing the bowl and the six screws holding the diaphragm.

    If you check this with no fuel in the line spinning he starter by using the button under the bonnet on the solenoid, you will see the diaphragm rising and falling when the pump is fitted correctly. The diaphram should move about 1/4 in up and down.

    If it only wobbles slightly, then it is on the wrong side of the cam (Short lever) or needs a thicker spacer (long lever).

    On my car, a short piece of hose under it was collapsing under vacuum when the pipe was dry. I had to prime the system using an electric pump between tank outlet and the steel pipe leaving the boot. Had me going for half a day. That was a temporary measure. I am now waiting til I am fit enough to replace the pipe from back to front.

    Hope that helps.

    Not a bad idea to check the diaphragm, I’ll take the top off and crank it now and show you how much it moves

  5. Yeah the old pump doesn’t have a spacer. I wanted to check the new pump one last time before disregarding. You’re correct in saying the new one probably needs a spacer but not a problem as the old one seems to work when installed.

    beloe is a video of the fuel coming out to the carb but going in to a container, I’m not certain what the flow is meant to look like

    i also attached a video of the fuel filter with the old pump, (note that I’m not revving at all the car is doing that on its own until it eventually cuts out) just incase that shows anything useful to diagnosis

     

     

     

     

  6. Okay making notes as I go:

    today I first tried Jerry can > filter > old pump. The pump fits on with barely any resistance whatsoever.

    I manually pumped some fuel in to the filter. Note that I was able to use the manual pump whilst it was installed on the engine block.

    Took the hose off at the carb at sucked fuel through to the carb.

    started up the engine and it ran for about a minute or so. The fuel pump was pumping. gave it some revs and then it just idled until it died.

    next I tried Jerry can > filter > new pump

    fitting it on had a LOT of resistance compared to the old pump.

    I cannot operate the manual pump lever whilst this new pump is installed, it does nothing.

    Sucked fuel through at the carb again, however this time it was a real struggle to get the fuel to the carb, I had to suck for ages until it finally bubbled on through.

    Started the car, it struggles to start then kicks in for maybe 3 - 5 seconds. I managed to quickly look at the filter and it appeared that the pump was working again somewhat, I took a video of me trying to start and Rev before dying, using the new pump.

    all in all it seems like…the pump, nor fuel lines are the issue. Right back at the start of the thread again! 😒 currently completely out of ideas of the issue.

     

  7. Well i decided to use the new pump anyway, the old pump can be my backup.

    Bringing back this previous point though...the difference in length and shape of the arms is concerning. I do feel like it's possible that i have the wrong pump and this may be affecting the issue somewhat. If anything would it not increase the pressure at which the pump operates by the arm being too long?
