Fuel Pump Problems!
Posted 12 May 2012 - 11:25 PM
started up the engine and it was making a splurting hissing sound and leaking petrol from it
thought it was the pipes on either side but they seem fine, turn it on and its leaking from the middle of the pump!
drained 5l in 2 hours!
the cars been sat for a while (2yrs) and has probably given up the ghost so started taking it off
the nut holding it in place is spinning and 2+hrs of swearing and wd40 and it still hasnt worked!
im wondering what to do,
do i hook up both pipes and run the mechanical one that ive had blanked off on the engine?
then do i still need the fuel regulator?
ive spent £900+ on the mini this month for its return to the road and cant really afford a new electric pump till next month anyway *doh*

The mechanical pump on the engine will be fine, and unless you have some weird carburettor setup, you do not need a regulator. The fuel pump actually pumps on its return stroke, driven by a spring, which by design limits the pressure to the correct value.

Regardless, with either an original electric or the mechanical SU pump you should not need the pressure regulator. As Oltonlad said, you should be able to bypass the electric pump using rubber fuel hose. Hard pipe should not be required as the only pressure in the supply line prior to the pump is cause by the weight (head pressure) of the fuel in the tank.

I don't think the quality of motoring journalists has improved since then, judging by several downright dangerous pieces of advice I saw in a recent Practical Classics magazine.
