D2 owners (or others), is your main tank line copper?

Mine is copper.

I changed the fuel line on my D2 to AN Braided Stainless Steel hose. Used a short stub piece of the original copper at the transfer pump and then used a compression fitting to make the connection with the hose.

Like n7gxz I used the original fitting and a short piece of the tubing then attached steel braided line to the tank. Works good for me.

Have a good day......Bill

What sort of problems did they mention? Mine is/was copper - I've cut it out because it's all mashed up.
Cheers,
Neil.

As noted below:

The aging process can be accelerated by the following conditions:-
•
Contact with zinc, copper or metal alloys containing them. These metals will quickly react with diesel fuel to form unstable compounds

@ Cysco, that setup looks really really sweet! I like that filter too!

Is this problem occurring because of the new slop that they sell as desiel fuel these days ? I have seen copper tubing used as a replacement for the tank to transfer pump for thirty yrs !

rjh-md, that's a fine question. I'll guess that our main lines of copper does not provide enough surface area to be of concern. My post was just to confirm what came on the D2 from the factory.

Now, a copper fuel tank would be another story. I agree, even with gasoline and copper (another no-no) has never caused a problem I am aware of, and I have been in the automotive industry for 35 years.

That being said, and with the short shelf life of fuel these days, here is what Shell says about Low Sulfur fuels in our equipment as a side note to your post.

Q4. May I continue to purchase Low Sulfur Diesel fuel if I prefer to use it in my older vehicle?

A4. Effective December 1, 2010, all diesel sold for on-highway use (eg service stations, truckstops) must meet ULSD quality. Diesel sold for off-highway use may contain higher sulfur levels in some parts of the US. Owners of 2007 and later model year diesel-powered highway vehicles must refuel only with ULSD fuel. Owners of 2006 and earlier model year diesel-powered engines and vehicles can refuel with ULSD without concern.

When I have trouble with a fuel line I just cut it near each end, slip a 1/2" fuel hose over each end and clamp them. If anything happens to the fuel hose it is easily replaced. Of course my Cats are for use not show. The original lines are steel with special bends and fittings that are not easily available, my way works for me.

In the old days, copper was used quite often on small engines, so what is this about?
gasoline and copper (another no-no)

Fuel Oil/Home Heating Oil Furnace lines were always copper?
why can they do it?
