    I can't tell you the number if the pump, as mine doesn't have one. If you are looking for the diaphragms, I have been getting them here. http://www.marxparts.com/fuel_pumps.htm. If your pump has the actuator attached, drill the end to get the swedged part apart, drill a hole into the actuator and tap for a screw. This has worked well for me in the past.

    Some or all the parts are used on the 22, might need a different arm. I think I have a 22 pump to compare. Will try to look. Anyone know better? Please chime in.

    Default R4 Fuel Pump

    Steve the fuel pump number should be STAMPED into the side flange of the pump. The casting numbers don't mean much. Kits are readily available
    Try Then and Now Automotive in Weymouth Mass 781-335-8860 Bill A.

    I just got a rebuild kit for my 22 from Now and then. Talk to Tom. I bet they can fix you up.

    Hi All
    Sorry i have not got back earlier, the reson i asked for part numbers is i have found a chap that had a shop that rebuilt carbies and fuel pumps and has a lots of kits to rebuild AC Delco pumps left over . That is why i aked for any updated part numbers from what is in the R4 parts book.

    Thanks for your help

    Looks like the 10 bolt style. If you check the OD and find a diaphragm kit to fit the OD & bolt pattern you should be ok. Do you have an R4 parts book to cross ref search?
