Hi all, I was hoping someone could give me a gut check. The powertech 12kw I have a leaking fuel line between the fuel pump and the fuel filter housing. I want to replace all those lines as they all don't look great. All the supply lines look to be 3/8 and the return looks like 1/4. Can anyone confirm? These lines are covered with paint from the powertech factory so aside from putting a caliper on them I have no way to tell the size for sure.
I believe you are correct but I would take them off and measure them and its inside measurement
that's needed.
If your close to a hose supply store, take the hoses you need to replace with you to the shop and match them up.
