Title: Pacific Fuel Injection in San Francisco
Post by: Nate on September 11, 2008, 15:45:38
Has anyone sent their fuel injection pump to Pacific Fuel injection lately?  What are they charging these days for a full rebuild?

I had my pump fixed and adjusted by Gus Pfister at Pacific about 10 years ago.  I brought him the pump one day when I had the need to visit San Francisco on business (I talked TSA into letting me carry the pump on board from Atlanta...no way I would ever get away with that post 9/11 !)  Gus is an amazing guy: honest and expert as in: if anyone knows more about bosch pumps I really don't know how it would be possible. He let me watch him go through the pump, replace a few parts from donor pumps of which he has hundreds in the shop (I had done the bone-headed move of removing the collar that attaches the throttle linkage, and put it back wrong causing bits and pieces to fly together/break off when I tried to start the car.  Don't do that, please).  It took him about 2 hours to repair, calibrate and bench test.  He charged me $250 which seemed like a remarkably fair price.  I would have paid that just to watch him work.
That's my experience anyway,

Best,
g

Gus is good, I've used him many times thru the years. The price however, is not good. Most of 2 grand for a complete rebuild!

I think I'm about to need the services of Gus and Pacific Fuel Injection.  Please let me know if I am on the right track.  I have completely gone through my 71 SL and it runs strongly.  The only thing is the smelly exhaust  at idle after deceleration.  The CO reading at idle is between 7.6 to 8.0 percent.  and I cannot lean it out anymore.  Is it time to rebuild the pump?  Sam

No, I would check for a leaky cold start valve first.

Does anyone know how many hours are involved to R&R the fuel injection pump?  I'm only concerned about the time required to remove and replace, not to tune and calibrate at this point.  Thanks!

Nate,
with the correct tools one can pull the pump in about 45 minutes or less.

of course there are some short cuts that can make the job go quicker.

It really is not too bad of a job.  The worst part is having to lay on the garage floor and reach up between the suspension to remove the lower mounting bolt for the pump to the motor.

The biggest tip is to make sure the crank is turned to the correct installation position so when you are ready to re install the pump it just can be slid in.

Thanks for the pointers and advice.  I really appreciate the insight.

In April 2000, Gus at Pacific did my '67 (250SL) Fuel pump -- complete rebuild and tune, including replacing some injectors (I forget how many), for $875... parts & labor.   I had work done thru a local (SJ, Hans Nissen Automotive --- now unfortunately out of business) MB only shop $75 of the $875 may have been for their remove/install labor and some mark-up at the time.

I'd guess same job today would cost more by approx. rate of inflation since then plus probable more scarcity of replacement parts?  At 3% average annual rate of inflation since 2000, the adder would be (to 2009) 1.3 times or in the range of $1000- $1100.... ball-park.
