Beware of Summit Branded braided hose!!!

[Dan Bennett]

It was mentioned upthread that the fuel was the problem. I agree.

Think about it - there are all sorts of grades of fuel, but do you have any idea of what they're made up of? Or because of the universal move to cost cutting if those chemicals have changed over time?

I used to work in an industrial setting working with pumps and piping that carried very nasty liquids, including one that would melt glass. There are a LOT of polymer materials available because different chemicals attack different things. The different versions are made to withstand different things.

So it is not out of the question that the liner breakdown could be eliminated, though it's highly unlikely it ever will be. You have to know what you're working with, and only the fuel suppliers do. They're not going to share their secrets.

Rubber inside the hose rots and the braid hides the cracks. I used to get hose free off a friend that worked at a helicopter place. They change the hoses on a scheduled basis.
But five years seems to be all that is safe unless you use Teflon lines. I got a 25 ft roll of 1/2" steel line and -8 fittings from Summit and ran two 12 ft lines from the pump to the regulator up front and a return.

I wonder how many trailer fires are caused by this type of problem?

It almost makes sense to put a valve right on the fuel cell so that you can travel (with the valve closed ) with no chance of fuel spilling while towing.

I do know one of my Division 7 friends drains his cell after every event.

The more replies I read here, the more I think I should do a webinar on how to properly assemble, leak free American made AN fittings and hoses that will provide trouble free service life for decades regardless of fuel used.

I made up my first -6 fuel line in the early 80s with Earl’s fittings and hoses.
