lately my old MK1 hasnt been starting too good, after mounting a new engine.(which seemed to have an electric pump once opon a time- as the fuel pump mounting hole was blanked off) anyway i put on my mechanical pump from the old engine.
there seems to be 2 problems of not getting fuel into the carb
- i found a tiny filter inside the float valve, which was blocked, and now cleaned
but still not getting fuel- the glass sight glass on the fuel pump is empty after she has stood a few weeks, which seems to indicate the fuel is running back down into the tank???
so is there a non return valve inside the mechanical fuel pump? if so , maybe mines leaking .
if not then maybe i should put one in the fuel line, or mount an electric ticker pump? or put a primer electric pump on???
