Everybody’s telling me that liner degrades fall apart, tears away from the main hose and blocks fuel eventually specially if you use low-grade fuel, screws up everything I just assume change out houses every year $18 worth of that black hose every season all I need is 6 feet or so of it I’m sure it will last in the sun for summer
It can degrade overtime. I kinda forgot about it in this video. I never had a problem with the newer stuff. It's the older stuff that's the problem. I prefer liner-less hose though.
Do you typically use the same A1-15 fuel hose line (but smaller inside diameter) to replace the pulse hose running from the fuel pump to the crankcase? Matt thank you so much, I couldn't have replaced my stator, power pack, & ignition coils (1974 Johnson 115hp) last summer without all your great videos!!!
One piece of advice regarding liner hose. It will not tolerate being put on and removed on barb fittings. The liner can bunch up restricting flow. I cut approx 1" off every time I remove a barb fitting.
This grey hose is rated and will keep the USCG inspector happy but face it that liner breaks down and the outer liner just gets stiff and brittle with time.
Apparently Sea Foam, which I use in all my engines, will eat that liner like crazy if left for long periods of time. It was explained to me by the boat mechanic that Sea Foam is fine if you use it up and run it through. If it sits up, its going to eat that plastic in your liner and cause you problems like folding in on itself as it separates to "pinch" fuel deliver or eventually disintegrate and clog filters, pump bulbs, carburetors etc. . This was diagnosing a boat that idled and ran at low speed fine but would not get enough power to get on plane.
How do you get a 20 year old hose off? Seems like it’s practically bonded to the deck fill through hull fitting. Any tips? I tried penetrating lubricant
