Hey guys, I have searched and not found the answer I am looking for. I am rebuilding my fuel pump and want to replace the black 5/16" line running from the bulb to the pump as the line is cracking and I am assuming at least 10 years old. The existing line is marine grade type A-1 low permeation fuel line. I am aware of the issues regarding the low perm hoses with the liner coming lose. My question is what are you guys using to replace it? Any suggestions where to get it at a good price?

I used automotive line the last time I did it, went 10 yrs. and was still good when I sold the boat.

Marpac blue line. Blue bulb also. EBay. 5/16 a little harder search.

A1 hoses should not deteriorate, even if they did they shouldn’t, and the hoses with internal linings that crusted were not A1 ethanol resistant.

I used automotive fuel line when I replaced all of mine in my boat 10 years ago. No issues so far. I fish all year.
