Fuel lines leaking HELP!!
1989 Class C motorhome on a Ford E350 chassis. Fuel injected, 2 pumps, fuel goes from the low pressure in tank to fuel accumilater to high pressure pump on frame rail then through filter. In tank pump and filter are new.
Start motorhome and get out to let it warm up, smell gas look under and see it raining down buy high pressure pump. Find out the line from the fuel accumilater to the high pressure pump is cut 95% through. The line is a somewhat hard plastic inside a protective rubber sleeve. For tempory fix I run a 1/4 reinfoced fuel line with some clamps to get unit running. Turn it on and it blow another line back by the gas tank. Got too dark to see what blew but it has to be the low pressure line from the tank.
Question whats going on? Ethanal in the fuel eating the lines. Have had this MH for two years and 5000 miles with out issue. These are low pressure line that are blowing. Possible a clogged return? Any one sell a complete line replacement for a 1989 E350 cut away chassis?
Any help will be appriecated
Thanks JKaz

Check & see if the plastic line is brittle, that blue gas line should be pliable a little. I have bent it in half & not broke it completely had to move it back & forth a few times to break it. You ruin it when you bend it but it didn't shatter or anything.

Line was still very flexible and not dried out. Took a piece to a ford dealer to pick their brains. Head Mech suggested maybe fuel pressure regulater. I figured it was worth a shot. Replaced it and have since driven a 100 miles with no problems.
