Is Viton hose really that much better?

[mohavewolfpup]

Is viton also good for immersion? One day I hope to drop my tanks and super clean them, then replace the shower heads with notched hose as some have mentioned. Eliminate some weak links. Manual tank valves would be nice also, but one step at a time. seems complicated

Why don't you look at the bottom of this page http://www.mcmaster.com/#hose/=qg3wov It is about 1/4 the price of Viton and rated for every possible fuel these trucks will see.

The only place e run 5/16 for fuel supply is from the filter outlet to the injection pump inlet. Mel has created a fine modified piece for this area. It does away with the olives and thats a good thing.. I believe its braided stainless steel so it wont ever fail on you like the oem line has a manner of doing..

SS Braided lines fail in the same way as any other rubber line. It rots and is affected the same way. The benefit to braided hose it its resistance to chafing. This does not apply so much to teflon lined SS.

I'm not sure about that. I know that other brand have specific hose that is rated to be submerged. I have looked at the Goodyear and Gates site and they both have charts on there that list what each type of hose is rated for. After all the feedback here, I decided that there would be no advantage to using Viton.

I have heard about this replacement hose before that goes from the fuel filter to the IP. If it gets rid of the need for the olives, I would highly consider purchasing it.

Anyone know if the 6.2L injector returns are the same as 6.9L? I got some gates 1/8" at local parts to replace one that was leaking, then 2 more, now a 4th :-( time to do all, none of 1/8ths have leaked but not sure for how long without clips, mine had none, but found kit that claims to b no clip, but wanting Bio safe, n they don't know, Gates n GoodYear have green stripe that r, but can't find local, n like said, not sure about size n really don't want to have to install clips

Submersible fuel line will have an SAE30R10 rating. This is what I used. It's only 1', but that was plenty for my tanks.

EDIT: Sorry, that was the wrong size. THIS is the correct one.

Some times hoses are lined with the expensive material to make them cheaper and have the chemical resistance required. If it is solid viton and not viton lined absolutely.

On the 6.2, I believe it's smaller.
Also never seen one with clips. Mine doesn't have any.

the kit at http://www.accuratediesel.com says they "clamp" free, several other sites seem to have same kit, my CUCV has clamps on its returns, I talked to Tim at AD and said they are 3.5mm ID on the 6.2L, he wasn't sure on BioDiesel compatibility but said he knew the kit was being used on engines running it, it would prob take yrs for Bio to eat em up anyway
