I used silicon hoses that are declared fuel proof.

was contact with gasoline at this interface) and pulled out. But now I am c
oncerned about the pickups at the bottom of the tank since a failure there m
eans bye bye all fuel (except for 2.5 gallons). I checked the ones at the bo
ttom of the tank and they look fine with no leaks but I am now concerned abo
ut the suitability of these coupling hoses.

ine). Only thing with same characteristics and after all, red stripe as in t
he old couplings is generally in A2 filler hose.

ot sure they would work.
