I've posted on this before but had to put the project aside while I replaced the head gasket on the Volvo 240. I want to reslove this issue

The IP is leaking. I brought it to two mechanics who claim to work on MBs. Both said they would fix it by replacing seals and both said it would actually require a new pump. Very disheartening.

Does anyone have experience with the pump? Is it possible to replace in the driveway? Is it sensible for an average home mechanic to do? If I pull it out, can I rebuild it? What are the chances a pro will screw up the car and make me regret trying to fix it?

I want to try to keep this car. It runs well even with the leaking pump. I think I can get a rebuilt pump online for $550 or so. Labor would be more.

I may be able to show up at Herndon next week. JohnHef was gracious enough to offer to take a look some time ago. Anyway, heres a picture of the pump

Fuel leaks at the delivery valve stands are common & easily resealed with o-rings & thin copper crush washers

As M.B. Doc mentioned, it's dependent on where the leak is. If the delivery valves on the top of the pump are leaking, these are $2.00 items that need replacement with the pump remaining in place.

If you can bring it to the GTG, John will know right away if the delivery valve is the culprit.

Replacing the IP should be the last possible option.
