Do as JimK says and replace it. Or, do what I am doing in the Clasco. Eliminate all that stuff and just draw out of the rear tank with an electric fuel pump and block off the mechanical fuel pump. That simply makes your coach into a 40 gal instead of a 50 gal tank(s) since both tanks draw down at the same rate until about 8 or so gal left. I never go that low anyway, so don’t need or want the “aux fuel tank capacity”. I would rather stop sooner and get some blood back into my rump so drive 250 miles and then look for fuel. The Carter 4070 that I am using is a loud but reliable spinning impeller type pump (4-6 psi that is not harmed by dead heading into the FiTech surge tank) so I don’t expect to revisit it for at least 10 years. I mounted it to the bottom of the floor with rubber isolators on both the motor mount and the mount to floor junction and then covered it with foam insulation. That kills most of the noise that gets through over the mechanical sounds of the motor and road. I left in place the previous electromagnetic pusher pump that was on the aux tank with enough fuel line to connect to where the Carter connects to the main line forward so if the Carter did unexpectedly fail I can hook up the pusher pump in a few minutes if need be. I like running spares.

The ethanol is attacking the rubbber on the olde ones as the rubber was no
designed to hold up to it.
If you have not done so in the last few years, do so now.
We do supply them .
