I think that the injector might need rebuilding. Compression from the cylinder coming back into the injector because of a problem with the nozzle not shutting or spring pressure too low. Try taking one from one of the other engines you have and use it. Shouldn't take very long to do that.
Manfred Date: Tue, 22 Jul 2008 11:58:56 -0500 From: "Harry Watkins" <[EMAIL PROTECTED]> I keep getting air at the middle injector nut during bleeding. The two outside injectors bled the air and only fuel comes out. This is a 3-cyl Mitsubishi and here is what I have tried. Replaced the delivery valve o-rings twice, once from my Harbor Freight box of o-rings, then I ordered and installed the OEM o-rings. I crack open the middle nut with the engine warm and running and the bubbles never stop. I did a hand pressure blue dye test on the fit between the fuel line and delivery valve and got a solid transfer. I placed the in-put fuel hose in a clear jug and ran the supply pump looking for bubbles and got none. It also passed the supply test of at least 8 oz in 15 seconds, which includes going through the pump filter and the main screw-on filter. I'm not sure if this is a clue or not, but I get very little return fuel. At idle I saw none, but I had left the line off during a test drive and it wet that area by the time I got back. I have ordered delivery valve springs and copper seals for my next try. Does anyone have suggestion on how a steady supply of air could get in?
