Fuel filler hose leaking on aux tank

[tampabronco]

The fuel filler neck hose is leaking where the hose meets the auxiliary tank. I got the hose, aux fuel tank and clamp at the time from WH. I tightened the clamp again but it's still leaking. Other than a wider clamp any suggestions?

might try going with a good quality all stainless clamp. the cheap bi metal ones you get at the parts store will come apart if you really snug them down. the screw drive will sink into the head being the head is cheap material.
take the clam off and check it out. see if the band slots are ok and what the head looks like.

Also check to see if the tank is cracked at the filler neck, hopefully not

I would also check the filler hose. Is it dry rotted, split or damaged in anyway? You can buy gas rated fill hose at a local industrial hose supply store.

My neck was cracked at the tank and I took it down and laid a bead of hot glue in there and it never leaked again.
