    Again I didn't look closely at the photo:rolleyes:

    If you have a joiner you could clamp the block off hose and add an extra length to test outflow without getting messy.
    Obviously have same level for outlet of both hoses when measuring.

    No I was clutching at straws with the tank outlet thing because as I’ve said I drain the tank way back before putting any fresh fuel in
    The mechanical fuel pump sucks from the tank doesn’t it?
    Because mine doesn’t

    You need a gravity fed flow to prime the pump
    They are poor at suction .
    No air pockets in line due to rising bends .
    Flow at hose outlet then finger over hose then push onto pump inlet.

    The tank is from a fuel injected tank. I've got one in my 76 single cab I'll check tomorrow which way around mine are.

    The outlet pointing to the rear of the bus is the one I've used.

    Hi
    Lots to check but you say it running?
    but struggles under acceleration?
    Any air leaks or broken air pipe on carbs (Try hard blips on link rod to rev hard in engine bay and listen for sucking?

    Pumps are mostly gravity fed and then once fuel is there it pumps out from there at the psi. Common name is a Facet style pump.
