This is the rubber line that we bought for the 6.2, its rated for up to 15psiDifferent gear:
This is your ip fuel return hose circled in white. It is the only 1/4” diameter line in the fuel system.
This is the one to replace with clear tubing, monitoring it at a glance whenever the hood is open and whenever the engine isn’t running perfectly happens in a couple seconds if the clear line is on permanently. Fuel-line.com sells actual fuel line that is clear and rated for the ethonal containing diesel fuel we have to buy now. Because it is not rubbing anything, the abrasion rating isn’t as critical here. Everywhere else in the truck the rubber hose is both subject to rubbing wear and is being eaten from the inside out by the ethanol in our fuel. So it should all be replaced with sae30r9 or higher to withstand it. Plan on dropping your fuel tank for replacement before it leaves you broke down somewhere. Verify what type hose you just bought for the filter to ip. If it’s wrong, don’t panic. It takes a year or so to do damage usually, and sometimes several years depending which hose you got.
The failing hose can damaged ip & injectors. Many people have replaced good working ip thinking they were at fault when it’s just hose failure. While others had the components ruined from the hose deterioration after the filter. So don’t panic but this is better done sooner rather than later.
