Fuel hose question

[windburn]

Time for fuel hose replacement on the boat. 1988 original is dry, hard and beginning to check. Do I need to replace with 3/8 marine fuel hose or can I replace with ethanol resistant automotive hose? I'm thinking I need marine hose but not sure what the difference is. Engine is a 3.7 merc I/O. I'll be replacing line from tank to fuel/water filter then line to fuel pump. All advice is welcome.

Yes to marine for coast guard and inshurance reasons,....kinda pricy but the right and only replacment..

Obviously one difference is cost.  Second is UV resistance.  Rubber deteriorates in direct sunlight.  Marine is more resistant to it.

I did mine this weekend - about $4.50 a foot for marine USCG A1 or A15 hose locally - might find it cheaper online. As already stated for the reasons above use the marine line. In addition it's kind of a PITA job, and your original marine line lasted about 25 years so you might as well just do it right. Don't forget to double clamp.

Yep. That's pretty much what I figured. Marine hose it will be. Thanks for all the replies/advice.
