Leaking Fuel Filler Flex Hose

The black hose section just down from the fuel filler cap is dripping fuel. The clamps are tight, so I think I should replace the hose section. I am looking for a part number and source. Is the second downstream hose section the same as the piece hear the filler cap?

When mine started leaking I went to the Hose Man and purchased a 2ft stick of hose designed for fuel and replaced all flexible sections on the fill pipe and I also replaced the vent hose at the same time.

Check the phone directory or Internet for hose repair shops in your area and they should have what you need it stock. I have also used the Hose Man to replicate HWH hoses and they have even made power steering hoses for me in the past.

Check your fuel tank vent hose as well.

It was cracked and leaking on our 2003. Used
6 of 5/8 fuel-grade hose to replace. As long as the tank is not full, not a bad job. Be sure there are not sags/drip loops in the vent line or filling the tank will be a CHORE.

The vent hose in ours was not fuel grade hose so it deteriorated and began leaking. After replacement with the proper hose, no more leaks!
