I'm back hoping to get more sugestions about why my engine keeps conking out. After I changed my inline fuel filter which was very dirty and full of crud between my tank and fuel pump the car was tested for about 30 to 40 miles with no problems, and I prematurely assumed the problem was solved. Well it wasn't. The engine continues to intermitantly conk out and when it does there is some tailpipe backfire then just stops. I noticed now when I opened the hood with the ignition position on off the clear fuel filter between the fuel pump and carburater is empty so the carburator must be starved of fuel. When I turned the ignition switch back to on the fuel pump starts ticking and the fuel filter fills up with gas and restarts with no problem All I have to do is wait till the fuel pump starts pumping again and it restarts again. I have checked the electrical connections on the fuel pump all looks good and the fuel pump is only 2 years old. I have disconnected the fuel lines and blown them out with compressed air they seem to be clear.
My first thoughts are fuel pump stops pumping fuel for some unknown reason, is the filter inside the fuel pump clogged? or should I just replace the fuel pump? Is there gunk in the fuel tank (dont know age of tank) clogging the fuel line between the fuel tank and the fuel pump starving the fuel pump? Is the electrical connection to the fuel pump intermitantly shorting out? Any and all comments and suggestions would be appreciated thank you
 
It sounds like a tank full of crud. Take out the fuel gauge sender and look down into the tank, if it is anything less than clean shiny metal you'll need to get it cleaned out properly. Then wipe a finger around the inside of the top, around the sender hole- it should also be clean metal. NB: be very careful not to snap off the screws and plan on replacing the gasket.

I have just resurrected a BN2 tank and could not get it clean without cutting open the baffles and scraping the muck out. None of the rust colored gunge in this pic is actually rust, it is all fuel residue and has been soaking in hot caustic solution for a week prior to this pic.

As noted above, clean the filter on the pump too.
