My 1990 Astra diesel has recently developed a leak from the fuel pump, tiny drips from the bottom of the pump when the engine is running.
Unfortunately, as far as I can see it appears to be coming from the area of a seal at the end of the actual pump body .
Checking this out on the net it appears to be a problem not a million miles removed from the use of low-sulphur fuels when used with older diesel vehicles.
I've recently been using Shell Super low-sulphur fuel and noticed that the problem seems to have coincided with this, whether or not this is just coincidence I don't know, but I wonder if this could be at the root cause, if so is there any cure other than a replacement fuel pump (which would probably cost more than the car is worth) such as a different brand of diesel fuel or some kind of additive. Thanks for any help
