I was tired of paying $45 for a fuel filter, so I took the factory canister off and bought a $14 gas barrel filter head and found a 5 micron filter 12 inches long that separates water also. Made a bracket and mounted it. Thought I had a fuel leak (small, but noticeable). Kept taking it apart for about a week and putting teflon tape on the threads, and even changed my filter head. One day I get this bright idea that maybe I am not doing anything wrong. Put a dye in the fuel to find the leak. Discovered injector lines are leaking around the fittings on the injector pump. Has anyone had this problem? Can I replace the injector lines only to stop it? If so, who sells the lines? Thanks Ryan

The injector tubes can be bought from Cummins

Wrong end ya senile ole fart.

Leaking around the injector pump I've never heard of bein an issue as long as the fittings are snugged up. Your not gonna like the price of buyin new lines. They're just compression fittings so as long as nobody has actually played Magilla Gorilla tryin to tighten em down and they split there is not much to go wrong. You may check to see that they are straight into the fitting, if your lines got cockeyed somehow that may cause a leak.

Are the lines sealed by flare or o-rings at the pump? I have been looking at parts stores, and some sell injector line (not injector) o-rings but can't tell me where they go. I drive this thing 130 miles every day to work and don't have time to take it apart to look at it, then put back together, then go get parts, and THEN fix it. Trying to save time.

oops sorry.................like Dennis says the connection at the pump is compression fittings, if they are leaking than make sure they are snug.........other than that yer prolly hosed, the only other alternative is maybe pull the fitting and apply some teflon paste and snug em up again

Just checked the parts manual and the only O-Rings shown are for the injector tubes.

Part Number 5011 885AA 6 O RING, Fuel Injector

It's the copper washer on the bottom of the injector Tube.
