What type of Fuel Lines do I need for a 2000 Fleetwood Discovery 37v, Class A, Diesel pusher with a Freightliner chassis?

I need to replace the fuel lines and I can't find any info from either freightliner, or fleetwood on the type and length of fuel lines I need.

1. Does anyone here know the answer?

2. Has anyone here done this and is there anything I need to be aware of in replacing the lines?

I had to have a fuel line made when I installed my FASS system, I went to NAPA, they had the correct hose and fittings. Just tell them what it is for and make sure it is diesel compatible.

Welcome to iRV2.

What engine in your coach? Cat or Cummins?
Which section of the fuel line do you need to replace?

My chassis has three different types of fuel line.
Plastic from the tank to the fuel/water separator, low pressure from the water separator to the lift pump, high pressure from the lift pump to the secondary filter, and from there to the cylinder head, and plastic from the cylinder head return back to the fuel tank.

Which section of the line are you trying to replace? All of it?

If you're talking about the line from the tank to almost the engine, it should be hard lined Parker:

3/8 on the return, and I think supply is 1/2".

On my 2000 Endeavor, somewhere around the transmission and rear axle those plastic lines change to standard rubber/flexible hose.

If you remove the hose that you want to replace, take it to a local hose shop - they will make you an exact replacement. If you aren't sure where to find a local hose shop, Googling "Parker Store" can usually help you. It sometimes takes a couple attempts to find a good shop, but once you find a good one, it's extremely valuable.
