i swapped round the fuel pump to cure the oil leak which i believe is actually the gasket not the pump.
But anyhow now the problem is that when the cars not got any revs on it it just cuts out, say your coasting down a hill it turns off, or if you want to go really slowly in low range it cuts out and i need it for the really slow quiet mode.
so what could it be? a fubard pump or just a turn of something at the carb, i know how to adjust the idle speed but i didnt need more revs before i changed the pump.

Could be the diaphram in the pump? Id put the old one on and see if the problem is still there?
If not put a new gasket in with the old pump

Use cardboard from a cereal packet, with some blue hylomar as a sealant have done that in the past on my old cars and havent had a problem. Instant gasket goo can have some strange reactions with oil and petrol.

i put the old pump back on and it still runs like sh1t.
is it petrol? i put £20 in it and its only did 23 miles of quite hard driving and idling.
what sort of electric fuel pump could i replace the mechanical one with?
