we have a problem with no fuel being pumped,
we know fuel comes out of the tank,the fuel lines are also clear,if the pump is connected to the fuel line,you can pump move the pump leaver and fuel comes out the pump, so pump is okay,but when the pump is fitted to the engine block,with the engine turning over the pump doesnt pump fuel,we tiried a new pump its the same one as what was removed,only thing not sure about is the Jackshaft,the dissy is turning,any ideas
thanks Dave

Its a 1850 it did run okay but broke down on the round Britain run,but not run since,when we took the fuel pump of there wasnt a spacer block and the new pump is the same size leaver as the one we took off ( think its the small leaver type )
thanks Dave

Hi, Is there a possibility that the fuel pump lever has dropped to one side of the cam ? This happened on mine and when refitting I found it necessary to find the lowest part of the cam with a finger in the engine casting and then fit the pump biassed to the left. When the bolts are done up evenly it then straightens out. The screwdriver slots in the bolts help a lot I found.

Hi Dave, I tried everywhere to get a small lever pump (very early) for my 1850. And ended up buying the later pump which does need the spacer, after that there was no problem. Worth checking as they both fit. At the same time i fitted a primer bulb so no more bad starting when left for a time as it's not my daily driver.

How did you get it going Dave? I think a compression check should be the next job
And can you take the plugs out and post a pic?

We fitted new plugs and leads,the old plugs were okay light brown colour not running rich,we did a compression check they were a bit low but all near enough they same,when it starts its lumpy and hard to start,i think its a head gasket blown,the exhaust is blowing either at the manifold or where the down pipe meets the manifold,any other thoughts
Thanks Dave
P.S Can the piston rings stick if the cars been left for a long time,and if they have, would running the engine for a bit unstick them ? color]

Hey Dave, thanks ever so for yours and Clive's efforts. Great to hear it running even if.....
But it is progress and the manifold to head gasket was definitely blowing
Cheers

Hi Dave, rings can stick and looking at the smoke behind? to me it looks like oil smoke as against steam. Oil smoke hangs around a lot longer.... I would put diesel down the plug holes and leave for a week. Then spin engine over (covering plug holes) and then refit clean plugs and try starting.

Hi Tony
This looks ideal for me as i am using carb cleaner or quick start spray, to avoid flattening the battery to much dragging fuel through after leaving the car for more than a week or so. I bought one off ebay and will fit it when i get a chance.
Might be a stupid question, but i have to ask as i dont know the answer, could you please let me know if you install this after the fuel pump or before or does it not matter.. or does it bypass the fuel pump as a separate route?
Thanks
Alan

Hi Alan, mine is placed after the fuel pump therefore you only need one extra piece of fuel hose and cable tied it loosely to the servo. I really do wished i had done it sooner
I think you will think the same
Let me know how you get on?
Tony.
