fuel lines? - Diesel Forum

I am in the process of installing an inline fuel filter and got lost following the fuel lines from the engine back.

So could someone tell me which line is the supply on the frame going to the selector, top or bottem?

I did mine a few years ago and on mine the top is the return.

Thanks for the reply, I thought the supply was on top. I switched to the bottem now. Just have to keep cranking to fill wity fuel now I guess.

The way I figured this out was to get the engine warm and then you can feel which line is warm and that will be your return since fuel has just left the heads on its way back to the tank. I dont remember any trouble recranking but I did have full tanks and the filter filled up before I could hook the lines back up. By the way, how do you like the monster box tranny? David

At this time I am having trouble with the M.B. I called the warranty department and they gave me a Work order number that any trany shop I bring it to can use to diagnose the problem but I havent time yet.

It feels like the torque convertor is slipping and then catching.ever since I installed the 2001 HPOP.
