I never suggested using automotive hose for a boat fuel system. Rather, I said there were other places to buy suitable hose, including an auto parts store.
46CFR Chapter I, Subchapter T, part 182.720E requires that flexible fuel hose used in construction of small passenger vessels meets the requirement of SAE J-1942. J-1942 is essentially SAE J30R2 hydraulic hose with a higher melting point. Gates C5M hose meets these requirements. Trident does not offer a hose in their catalog that does. USCG requirements for fuel hose used in small recreational vessels have USCG standards A1 and A2, both of which are met by SAE J-1527 (which is similar to ABYC H-33). Trident fuel hoses all meet J-1527. A number of automotive hose providers - including Goodyear - offer J-1527 hose. Remember SAE stands for Society of Automotive Engineers. Manufacturers who cater to automotive markets have higher production volumes and economies of scale (and maybe scope) vs. marine product manufacturers. And the auto parts market is a lot more competitive than the boat parts market. So pick your poison: J-1527 or the commercial J-1942 hose. And then check to see how inexpensively you can get the hose from multiple sources. BTW, Joe, fuel hose on aircraft just has to be "suitable" for the application, but the requirement for the fire sleeve is in 14CFR!,C,23,e.

Airplane hoses have fire-sleeves over them and marine hose is about 3-4 times as thick as it needs to be so there is a lot of rubber to burn away before it would have a hole in it. Auto hose has neither.

And the specs are the same regardless of the manufacturer. So use whatever is less expensive. You might even get a price on hose - probably Gates Rubber - from your local NAPA store. Since it's not "Boat Hose" it's probably significantly less than either WM or Defender.

Exterior looks great but interior shows a number of corrosion issues. Had to remove fittings and saw off the inlet fitting to get the tank out of the locker so was committed when I did that to getting a new tank. That said, the hidden corrosion on the interior tells me an incident was in the making so replacing now is a good idea. Have replacement aluminum tank made by Luther's in Bristol RI who by all accounts are the "go to" source for a tank made right in all respects. Not the least expensive by any stretch but by far the best value or so they say :) Question is replacing the hoses. West carries the Shields brand, Defender the Trident at a cost differential of some 20% less in price. Specifications are essentially identical. Any reason to not embrace the lower price??
