Yep, it sounds like you did a retrofit conversion to 300Tdi. I'm doing a conversion from an existing 2.5NA diesel. Not sure if the fittings are the same size but I'm guessing that I'll need 5/16 ID. Maybe someone with the same setup as me can chime in.

Consider putting the ends of the 1/4" hose into hot water for a minute to soften it up before pushing it on.

The stuff I had at first was that gorilla hose and it has an enormous sidewall. I tried the hot water trick but it didn't help. I'll give it another go with 1/4" viton next weekend and see how it goes.

Running with biodiesel is another reason I want to swap the gas engine to diesel. Alternative fuels.

I think the pickup is 10mm OD / 8mm ID and the return is 8mm OD / 6mm ID.

Parker has a biodeisel rated hose that works well that is 5/16 that I have used on several older rovers. Just finishing up a late series IIA and ran 5/16 from the stock tank to a 2.8 under the hood. The fittings on the lift pump are slightly larger, but the 5/16 slips on without too much effort. Been running biodeisel for many years and this hose has held up well. I used the 5/16 for the return line as well.

I used McMaster Viton (green) hose as dimension spec'd by Mark above. They work great.

Has anyone found a good source for Viton fuel filler hose?

So it looks like the correct Viton hose for tank --> sedimenter --> front of truck is McMaster part# 5119K86

And tough as a crackhouse pit bull. I used clear nylon for most of my runs. You hit it with a heat gun and slide it on the barb and robert is your mom's brother.

It is if you make sure there's not a kink in it that will pool fuel. Mine started softening and sweating from B99 puddling. Once adjusted it's been fine.

In researching fuel hoses for my Webasto I found this in the interweb. Have not verified it myself. I'm considering going with the Gates Barricade Fuel Line. Any thoughts or comments on that one?

Biodiesel Compatible Fuel Lines

Goodyear part numbers 65148 thru 65153 & 65161 thru 65163 meet SAE specification J30R9. B100 compatible.
Gates part number 4241G and 4241M for marine use.
Kuriyama part number A4143.
NAPA fuel injection hose part H205.
McMaster Carr Viton rubber tubing part number 5119K51.
Apparently any USCG approved fuel line with SAE J1527 type A-1 approval is B100 compatible.

The H205 has been superseded to H357A.
Very useful info... thanks for posting.

Does anyone know the PSI requirements of the fuel lines for a 300tdi? I am trying to determine the working pressure for the lift and injection pump as well as the Webasto Thermotop C pump. The fuel line I was going to buy has an operating pressure of 50 PSI. Is this sufficient? I've read somewhere that the fuel lift pump pressure is 3-4 PSI @ 1800rpm. What about the injection pump? I just want to make sure I get a biodiesel compatible fuel line with the adequate PSI rating.

Fuel Line

I talked to Webasto and decided to order their own branded fuel line. The tolerance is a little different they said so important for best fit. The line and the Thermotop C are rated up to B20 (20% biodiesel). Their line is ordered by the meter and the part# is 9028379A.

your pretty much under 10psi for everything except for the metal IP to Injector pipes. Don't sweat it. (pardon the pun)
