Re: Intermittant loss of power when accelerating

["Ewan Hopkins" <ewanhopkins@hotmail.com>]

Assuming your car is an '86 model, I have had a very similar problem, 
usually when the fuel is below 1/3 of a tank.  I'm not sure exactly waht 
the cause was but I replaced the fuel pump, which was pretty noisy, and 
I also took the lifter pump out of the tank and the mesh screen filter 
was pretty clogged.  There's every chance that either the clogged filter 
was making it too difficult for the lifter pump to pump enough fuel when 
the tank is low or that the lifter pump itself was on the way out - I 
just replaced the whole assembly with a secondhand one.  If I had had 
more time, I would have cleaned the lifter and put it back with my old 
fuel pump, to try and pin down the problem.  The problem has now gone.
Note that if you do replace the lifter assembly, it has to be one from 
an FI car,  as the carb versions do not have the pump.  I think also 
that MKI and early MKII FI tanks do not have the lifter pump - that is 
certainly the case in the UK.

Cheers,


Ewan.
