For those of you who remember, I posted about the problem I had in filling my gas tank on my 2005 Sea Breeze on the W24 Chassis.
Well, problem solved! I explained the problem to a local RV service shop, J & K Automotive & RV Service in Camarillo, CA I told Mike, the Service Writer, he did some research and told me he thought he may have a solution. His mechanic found a light kink in the vacuum return line, which they straightened out, then they cut about 4" out of the fill tube after the rubber hose connector. Then they cut the rubber hose connector that runs from the fill tube to the main line and straightened it out. They cut the filler tube hangars and created a more pronounced slope from fill to tank.
Went to Costco and set the pump on mid-volume and....voila' it now fills normally!
Thank you to all who wrote back with repair suggestions. jacking up the rear jacks helped in most situations, but this is a permanent fix.
