Hello all, new member checking in and asking a question.

[LesleyW]

We just picked up our new to us 1974 2002tii bought from Bring a Trailer. At first it didn’t want to run well at the 6,000 of Colorado Springs, but taking away some fuel has sorted that out. 

My question, I’m going to rebuild the Warm up Regulator with the kit from this website and was wondering if anyone knows of a Kugelfischer rebuilder that is state side?

 

Thanks, Wil and Lesley

Hi, nice car! Welcome.. 🙂

 

The word I've always heard is the pumps are super reliable, perhaps the new WUR, possibly injector cleaning/testing is enough? I totally get testing + validation for the sake of completeness however.

Jason’s right that the injectors and WURs often clean up well, and I also wouldn’t worry too much about the KF pump if the car runs smoothly at all at any altitude. They really are kind of bulletproof.  Before I’d touch the KF pump I’d inspect every filter on the way there.  I think there were four when the car was new: one in the fuel tank (a screen), one at the fuel pump (also a screen), one a big canister next to the radiator, and one at the KF itself.  Be sure all are clean and that there’s no debris coming through the fuel lines. If you remove the canister filter and the gas that pours out has a blackish hue, you may need to change out all your fuel hoses.  Use high pressure hose from Belmetric, a good aftermarket supplier of fasteners and other stuff for our cars.  There are various oufits that can clean or recondition the injectors, including some on bergie33’s list.  They should fire at somewere above 475 lbs per square inch, if I recall.  Do all this, and check your throttle linkages for correctness and tightness before you turn your attention to the KF pump itself.

 

The WUR is a bit of an adventure till you figure it out, but you can test it and clean it by taking off the car, which you can do without removing anything else.  DLacey’s kit is a marvel, if it comes to that.  If you have startup issues up there in the cold thin air, you may need Jason’s improved startup injection circuit board, another marvel.

 

I may be forgetting a few things.  There are a ton of posts on all these topics here on the faq about all this. Ask me how I know!

[0257]

Occurs to me you may have been looking for a KF rebuilder to rebuild the WUR…?  You don’t need a KF specialist for that.  Any mechanically inclined person can do it based on the instructions and maybe a little background knowledge of warmup regulators. They were used on various cars of the era, so a good mechanic with experience with mechanical fuel injections may be your best bet if you don’t trust your own skills. Or any decent machine shop.

[bergie33]

If you are only cleaning and testing the injectors, most good diesel shops can do that and they are more plentiful locally. Should be able to find a few in Colorado Springs. 

[LesleyW]

Thanks for all the great replies. I’m going to rebuild the WUR myself to see if that helps the cold start, rich condition. I wanted to have a refreshed pump for when I do the Metric Mechanic engine at the end of the year. Normally wouldn’t be replacing the engine, but someone along the years stripped out #1 spark plug hole and that gives me future tuneup anxiety, and why not pick up a few more ponies.
