Fuel Pump Question

[Hazey-n-Marc]

It took ages to get any thing out of mine after changing the (mechanical) fuel pump, someone had fitted an electrical pump, in line with the leaky mechanical one, wired straight to the ignition (so it was continuously on) and had bolted it straight to the shell, sounded like a pneumatic drill!!
 After replacing the mech pump and removing the electric pump I placed jump leads from my other car to the fiat and cranked it for days, eventually (sometime the following sunday I think) it pulled enough through to splutter in to life.  
It would have been a bit quicker if it hadn't been drawing in air, triple check all of the pipe fittings, it will save time in the long run.  Jubilee clips are crap, make sure you have proper fuel line clips (about 25p each)
tighten until you cannot twist the pipe.

You can prime the Carb, I have a washing up liquid bottle with the base cut off, a piece of rubber pipe connected to the squirty end, Then connect the pipe to the carb and dribble some petrol through to fill the carb, with the carb full it should run a minute or two. Connect the pipe from the pump and start the engine, this should pull the fuel through assuming the pump isn't faulty.

Sounds like if you try 3 pumps and nothing happens, it's not a pump problem.

Hoses in good order? checked they havnt split a bit near the tanks?

I have no doubt you can suck harder than a little fuel pump so sucking doesn't prove anything.

I know it's probably you want to keep it standard, which is nice, buy a spare starter

Ordered a new pump from gerstle cos the other looked a bit too cheap and was not sure about the seller, have to wait and see!

I know a classic car owner who had the same problem as yours. I mentioned the issues you have been having with the engine stalling despite cleaning and replacing many parts. He reckons the fuel tank is full of dirt. He had his fuel tank flushed (chemical?) and drained. He was amazed with the amount of dirt that was in the tank. After flushing, the performance improved but the engine was still stalling, although not as often. He ended up replacing the fuel tank with a new one, and the problem appeared to have gone away.
