Hey guys.
I have a 1964 230SL and the FI pump is leaking oil pretty badly. I've taken it into my mechanic who has been in contact with Gus at PFI to confirm the problem.
Together they have come to the conclusion that it is in fact time for a pump rebuild.
My mechanic has received a quote from Gus at PFI. Separately I called Fairchild Industries and Black Forest LLC.
The Black Forest price seemed in line with Gus', and every comment on this site about Black Forest has been very good.
Fairchild Industries pricing was much less, although they admittedly do not focus on the cosmetics of the pump unless you request it.
If you have had experience with a FI pump being rebuilt, would you mind letting me know your recommendations based on your experience? Or if you were to send another pump in, who would you recommend?
Thank you for your help and thoughts!

Gus built and calibrated my pump several years ago. My experience is that he is an honest, capable, and interesting fellow to deal with. I don't know many people about whom I can say the same.

Depending on where the oil leak is, most of the external seals can be replaced without rebuilding the pump. They are merely cover seals. A kit for just this can be purchased through Bosch. The only area for a leak that cant be repaired in the field is a worn throttle linkage shaft where it enters the pump.
Jerry Fairchild would be the best option for this type of repair if your mechanic does not feel confident in doing it himself.
If the pump is leaking because it is being contaminated with fuel and therefore overfilled then yes a full rebuild is in order.

I was told by my rebuilder that the throttle shaft seal requires a special installing tool to do the job and since the position of the arm on the control shaft is highly critical, it's not a job for most of our members here to even consider.
I knew someone who removed this arm to install a new ball stud and for some unknown reason decided to start his engine before the arm was back on and really damaged his pump. We were able to fix it for him but I feel he was lucky.

I have used both Gus at Pacific and HANS at H&R. Both are great to work with

I've had experience with H&R, Pacific, and Fairchild. Two owners, whose cars I worked on, reported that pumps from H&R had to go back for re-fixing. I had a pump rebuilt by Pacific and it needed adjustment to get the engine to run right and the WRD still does not work right. I had a pump calibrated by Fairchild and it worked perfectly.
I like Fairchild because they are reasonably priced and you can talk to Robert.

Everyone will have reasons for going to or not going to certain places. I place no more stock in one preference than the other. Every place can do great work and/or make mistakes - it's how things are sorted out that counts. The perfect mechanic is like the perfect family - the only time you see either one is when it's a picture on the wall.

I am looking to rebuild an injection pump for my 230SL. An archived post discussed Gus AFI and Fairchild Industries and some others. Alas, I cannot find them on the web and would be very grateful for recommendations and contact details anyone can offer.

This is for Fairchild.

My FI pump was gaining oil. I was concerned and called Fairchild. He said he would not pre-guess the problem without looking at it so I shipped it to him. He called me and gave his diagnosis and $ estimate an said all in all the pump needed sealing up but was in pretty good shape. Turn around time was a little over two weeks and the final bill was less than his estimate. It works well now. So mine was not a full on rebuild and was about $500 I think. I am very satisfied with his work.
