Toy Hauler Fuel fill remedy

[jeeperx2]

Had issues with my 2018 4113 taking fuel in either tank... generator & auxiliary tank.. neither would take fuel. Started taking things apart & investigating why.. the fill necks were mounted in the trailer skirting @ a level that the connecting 2” rubber hose was nearly level with the tank inlet with a tinny hump over the frame of the trailer... I’ve seen tons of posts on the web about this issue so here is my fix to the problem & tanks fill @ full throttle @ a regular gas pump

Sorry for the sideways pic

Did you remove the backflow prevention balls, or just raise the filler necks? My Seismic 4116 still has the same filling problems after raising the necks as high as I could, about 4". I never found the balls. I am now planning to build a 'L' adapter out of aluminum tubing. Funny thing, Fuel transferred to the generator tank with the pump will flow at full volume. At the truck stop a half hour for 29 gallons in the front tank and an other hour filling the rear auxiliary tanks 47 gallons.

We bought our Seismic in Gulfport Ms from Dads Camper Outlet and were pulling it back to our home in Alamogordo NM approximately 1500 miles. We were having turbo problems on the Big Blacks Beast the '15 Ram 3500 drw, so we knew it would take at least 3 days maybe 4 days of Wal-Mart camping.

With the generator running 24-7 it would take a lot gas (or so l thought) so I filled both tanks. It only used the 29 gallons in the generator tank running almost 6 days.

It was a good thing I didn't need to transfer fuel because the pump was plumbed backwards. See my post elsewhere.

I did remove the back flow preventers prior to raising the fill necks.. I was going to try to add some weight to the balls but just decided to take them out altogether... haven’t had any issues with gas slopping out the cap. I was concerned I would have issues with that.
