Lift Pump O-ring/gasket set, where can I buy?

[JEBalles]

I believe diesel is leaking into the motor oil 1981 300sd. Smells different than 240 and looks less viscous. Oil level has also gone up considerably and it hasn't even been driven that much. I searched the archives and it looks like the most likely culprit is the lift pump o-ring. I'd rather not spend 150 for a new pump when all it needs is a new o-ring, but I can't, for the life of me, find where I can buy the darned thing.

The local bearing/seal supply house also sells o rings. Take the old one with you & a new matching ring will be <$1.

Should I just replace the o-ring, or do I need to replace more seals?

I'm leaking fuel into the motor oil, not the other way around. Wouldn't those be separate problems because the pressures on each system should be the same on every engine?

I understand that that your situation is different. But, like I said there is only 2 areas you can get Fuel in you Crankcase Oil. That O-ring or from the IP Housing where the Elements go in.

I have seen the O-ring leak on other Bosch Fuel Injection Pumps and Fuel got into the Oil. That guys Thread is the 1st time I ever read of the Oil being sucked into the Fuel!

OK I have my O-ring that I ordered from the BMW cycle place see pic at bottom for comparison. The cost was $1.92+tax.

The reason I did not try to buy the O-ring at a Bearing Shop is because the last time I did something like that the counter person *****ed that it cost them more than the cost of the O-ring to do the paperwork and wanted me to buy a bag of O-rings.
This is not to say that you would have the same experience at a place local to you.
