Primer Pump
If a primer pump failed, does it introduce a air leak into the fuel system/lift pump?
And if so, how can I seal the primer pump so it doesnt leak air until I get a new one? I'm narrowing the list of the problems with this car, and I'm getting more and more excited every day.

If you are in a huge rush....you can get an upgraded one at NAPA if you have one near you. Depending on how hosed up the old early style one is, you might not be able to seal it up.

Are there o-rings or something that can be replaced? Right now, the primer pump doesn't actually pump anything.

If you have a non turbo 300D then this will be right up your street.

You're my Hero Army. That looks not-so-hard to complete. Would I need to rebuild the fuel pump just to change the primer pump? Seems to me that the primer pump should be able to be switched out without removing the IP

With a crowsfoot attachment its an easy swapout, awkward but not impossible without one and can be done without taking anything off the car. I've done it on two, without a crowsfoot.

If the old white knob version. Just slip a ballon over it and squeeze out the air should stop any air ingress. I have no ideal how long the ballon material will last when subjected to oil. Carry a spare baloon perhaps until the new primer pump arrives.

A condom might work, carry a few in the glove box in case a need arises.

At the top of the Aluminum Hand Primer the Body is crimped over and the Aluminum is fairly Thick. This means you cannot take it apart without some major grief.
Unless something has rubbed a hole into the Aluminum body air has to come in under the Knob and shaft. If you unscrew the knob and can pull it up some; wipe of any Diesel Fuel and put a nice thick bead of Silicon Sealant under the Head of the Knob and shove it down slowly and till it bottoms out and screw it back in tight. Let the Silicon Cure and just the way it is coat the area again with Silicone Sealant and again let it cure. The Fuel Injection Pump pictured in the thread is an M type Pump. On the M Pumps the Hand Primer sits close to the Fuel Injection Pump. On the MW type Fuel Injection Pump the most of have the Hand Primer sits in a different position and is a little easier to get at. And, the Hand Primer can be removed all by itself. How to do that is well covered in the DIY Section. DIY Repair Links http://www.peachparts.com/shopforum/forumdisplay.php?f=82 http://www.peachparts.com/Wikka/DoItYourSelf
