BTW, this is what can happen if you don't get it fixed...

A huge thank you to both Mr John DeGregory, and Mr Rollin Jones who have been both very helpful in getting the fuel pump rebuilt and leak fixed in the car.
I'm now re-installed and have primed the fuel system by filling the bowl (via the vent at the top), however, after 3 times doing this (and running on the fuel in the bowl only), the fuel is still not apparently being drawn from the tank. Can anybody advise the correct method of bleeding the fuel system after removing the fuel pump and having the system completely dry from the fuel filter forward? I had hoped filling the float bowl would have done it. I have all vacuum hoses connected,
Many thanks indeed, this forum is amazingly helpful.

If not, then you have some kind of fuel delivery issue between the tank and the fuel pump. A GOOD engine mounted fuel pump will have MORE than enough suction to suck gas from the tank. In fact, the tank is positioned HIGHER than the fuel pump, thus, gas SHOULD just run to the pump by gravity.

Fuel up to the fuel meter of the FI unit is ONLY supplied by the fuel pump (either the engine mounted pump or if you hava an elec pump). I would suggest separating the hard fuel line from the fuel meter, slip a rubber hose onto the hard line, crank the engine with the starter and observe to see if fuel comes out the rubber hose.

I know of only one person who has all the parts, special equipment, and machining skills needed to completely restore an AC gear pump. He is Rollin Jones in Newark, Ohio. He even has new center sections with gears that he can install when necessary. His phone number is (740) 344-1686 (Central Time Zone, six hours ahead of England).
If you've never replaced a gear pump shaft seal before, I suggest you send your pump to Rollin. He can tell if a past butcher has already ruined the carbon bushing behind the seal and/or gouged the pump wall seat area with a chisel. That happens a lot, unfortunately.
Good luck,
Jerry

You can very easily mess up a FI pump.. Cost was $180.00 which included return shipping.

About 6 months ago, I developed a leak at the gear pump as described in this thread. Sent my pump to Rollin Jones. Rollin called me and told me that I still had the original neoprene 1963 vintage seal in my pump. It was replaced with a newer ethanol friendly Viton seal. Turnaround time was about 2 weeks.

Chuck,
Did he do any repair to the pump other than change the seal. Check for wear or replace anything else?

Great tutorial, guys. Special thanks to Jerry for his insight and help. The FI threads, to me, are always the most interesting and the most technically interesting. Thanks, again, to all of you who participated. It was very informative.
