I ordered the return line kit from Pensacola Injection. Got in checked every thing hoses looked ok. Put it on. Drove ten miles to get fuel. By time I got back the hose at the filter had already got soft and come off. Cut the end off and put hosse. Went out today to work on my problemtic glow plugs. The same line was soft again and wet plus the crossover from rt to left was off and wet. I just got back from Orielie's with 4 ft of gates hose.

 

yeah a lot of us learned that one the hard way.

I know buyer beware. I did keep all the old caps. So amother day laying over the engine. Still got less than a 500 on the truck. Do. On complaining about that just the junk parts that are out there
