In a message dated 98-03-16 12:05:14 EST, you write: << I noticed a fuel leak. Seep actually. Where the fuel line connects with the injector 3rd from the back (dont know if that is properly numbered 2 or 3) there is a small amount of fuel that leaks from this connection. Any quick fixes? >> Kevin-- First off, welcome. My lawyer would be glad I put this in: a warning. NEVER EVER NEVER work on Deisel injectors or their fittings with your motor running. Your fuel is under many hundreds of psi of pressure, and your injectors, or a leak from them can littterally inject fuel through your skin and into your muscle tissue. NO JOKE. Motor off=no danger. That being said: There are only three points on each injector that can leak. There is the center pressurized connection, where you see a steel pipe surrounded by a 15mm (?) nut, or the two identical overflow pipes, which stick out like ears from the injector and have black cotton-covered rubber tubes attached. It is highly unlikely that the center pressure line is leaking but you can check. There is a special "broken-ring" wrench you should purchase for tightening these, but if you are careful, you can use a simple open-end box wrench. You don't need to make these Magilla-Gorilla tight. about 20-25 lb/ft is good. Anything more and you may ruin the faces on the nut. More likely, it is one of the little rubber hoses that take to excess fuel back to the tank. These should be replaced every few years, if you are anal, like me, (if not, wait for them to spring a leak, and then replace them). Also, be double sure to replace the end plug you will find on the injector closest to the timing belt. Buy an extra while you are at the dealer, and throw it in the glub compartment. All of this tubing is press fit and pretty self-explanitory. drop a note if you run into trouble. gmbulley cary, nc "Farmers for Fairness = Ponds Full of Hog Feces"
