Have spent quite a few hours this week re commissioning the Pilot after its 8 year lay up, the fitted 6 volt battery was under powered and dry so a new one with higher cranking amps was purchased and fitted. The engine now turns over smoothly on the crank handle with the plugs out after a week of WD40 down the plug holes. The original fuel pump was for an earlier car and did not have the hand priming lever, no petrol was coming through after a few dozen crank turns so I suspected the fuel pump might be dried out and stuck, took it to pieces and it was dry but quite clean and functioning as it should. I refitted it and hand filled it with petrol still no good. Fortunately I found an original NOS with correct primer which I bought and fitted this morning, half an hour of priming and still no fuel and yet if I sucked on the fuel pipe I could bring petrol through. I blew air down the pipe thinking there may be an in tank filter, good healthy bubbling. Crawled underneath to check the pipework around the tank thinking there may be a split or loose pipe. Completely hidden behind the fuel tank I discovered that a non standard electric pump had been installed at some point, switched on the ignition and returned to the electric pump, silent, remembering the old SU fuel pumps I gave the pump a few smart taps and tick tick off it went and voila! petrol at the carburetor. Next step is to refit the plugs and see what happens.
