I have a 1990 560 SEC European Spec ( Japanese Import ) that is absolute
pristine condition.
I havn't been driving it over the winter, except for a good warm up run on a
dry sunny day.
This afternoon I was going to take it out for a drive, started it and left
it running in my drive while I moved another vehicle.
I noticed a puddle behind the right real wheel, and noticed something
spraying under pressure out into this puddle from the underside of the car.
Suspected fuel, and smell test confirmed my suspicion.
In this location what could be the source of the fuel leak? And what would
be the fix?
Any and all help or advice is greatly appreciated. |

If its spraying with ignition on there is a leak in the presssure line
after the pump. If its leaking ignition off replace all the rubber hoses
between tank and pump.

It is spraying with the ignition on.
So is that a bad fitting, or do I have to replace the entire line? >> Stay informed about: Fuel Leaking |

Most probably corrosion at the double pump/filter connection
aluminium/brass with alu fittings.
For cars older than 15 years I recommend replacing both pump and filter
together with the matalic cage. You get an impression then of the state
of rest of the assembly there.
Depending on the fuel history (lead, unleaded, additives) over the years
in your country it may be nessecary to replace all the rubber parts too.

That is definitely fuel pump area. Most likely are the fuel hoses... the
rubber one that are leaking. I suggest you let your mechanic replace all the
rubber hoses in that area. Change all copper washers for hard lines and
change your fuel filter while they are at it.
Don't drive the car... let a tow truck take it to shop. The thing is all the
fuel will drain down when replacing the hose so it is not a job to do at
home nor when full tank. >> Stay informed about: Fuel Leaking |

Hmm, makes you wonder what keeps my 20 yo car going. Only rubber
casualties so far are the tires and one broken orthopaedic seat valve.
Who needs that anyway.
