I have a 1970 eldo it's previously been sat for a few years- the
windscreen sticker says last test ran out 06-06.
I have had it for two months, driven it about a week. I've done a shed
load of work and now have a couple of things that I'm not sure of.
Firstly it had an electric fuel pump and filter mounted on the wheel
arch just behind the battery. I have just replaced this recently with
a 6psi carter vane-type pump. Seems to work well but when I drive
up a very slight incline at about 10-15 mph the engine almost imediatly
fades and stops as if run out of fuel. I turn the ign off, pump gas,
and for the first few key turns i have no starter!? Then on fourth try
it's all back and I carry on. Any ideas?, I expected it was due to the
pump being mounted too high and far from the fuel tank but it happened
with a full tank of fuel today. And why do I lose the starter motor
Ok secondly - I got a clunk, usually when manouvering to parkup. It's
from the front right around the torsion bar block. When I reverse
then brake:CLUNK! then I go foward and brake :CLUNK! or sometimes
the clunk happens when i put it in drive or reverse. The only thing I
see worn under there are perished control arm bushings. And a small
split on a sway bar bushing. Could it be the actual torsion bar? If so
what exactly is on the end of it that would clunk?
btw does anyone think it would be useful if 67 -79 eldos had a seperate forum?
It originally would have had a mechanical pump but when i got the car it had a basic electric pump installed which i replaced as it was cutting out and had a spring loose inside so i presumed it was this that caused the problem.
id rather keep the electric pump as i dont know what troubles are connected to the original setup. plus like i say it seems to work fine aside from this problem!
Also in the near future i hope to fit an LPG sytem and i'd need an electronic shut off for the petrol line.
Hi, i sorted the petrol problem. I moved the new Carter electric fuel pump to the rear just to the right of the tank, its now as low and as close to the tank as possible and works a treat.
Im still having a problem locating the CLUNK though, can someone tell me where the engine and transmission mounts are located so i can check them. Thanks
