It's just my recommendation based on 35 years of experience. I once found that Bosch apparently started using thinner material for the male pins in the injectors and that the old female connectors didn't fit replacement injectors snugly as a consequence. I can't be sure of my measurements, because it is hard to get in there to measure, and there might be some corrosion on the old pins which could mislead me. At any rate, I frequently find that these connections are loose and intermittent. This is easy to test if you have one of the Bosch FI testers, but possible otherwise, especially if you have a second person to help. To disassemble the connectors, you need to make a tool. Mine is a piece of 1/16" stainless steel welding rod filed rectangular on one end. I slip it into the special opening on the fact of the connector and push the locking tab on the female pin back from the step in the housing. Then the pin can be withdrawn from the plastic connector shell. Once the pins are out, you can test them for tightness individually on an injector. If they are loose, squeeze them very gently and try again. BE VERY CAREFUL not to overdo it. Keith, do you still have bags of replacement pins? Remind us again of the price. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
