Case IH 385
Has anyone had luck changing the fuel return lines on a 1990 diesel 385 , these are the short lines between the injectors, they measure around 4 1/2 inches long.
Case wants $235 for a return line, All I need is the right size line, the fittings on the injectors are just a push on barb fitting.
Thanks for your help !!

I use 3/16" clear plastic fuel hose, cut into 41/2" or 5" lengths as needed. It's easily found on line, just be careful to read the fine print. You want hose that's fuel and heat resistant with the thickest material you can find. The thin stuff usually starts to soften and leak from the heat sooner than the thicker stuff. I prefer the clear plastic over rubber because the plastic force fits onto the barb and doesn't need a hose clamp.
