So kinda going thru my to do list on my motorhome. Being that the Covid numbers were clicking up around KC we decided to lay low around the house.
So thus all the projects on the motorhome.
The next project is to work on the fuel tank system. Never been confident on the gas gage. I had a mechanic drop the tanks and replace all the
hoses. At that time he told me about only one sending unit working, so he set it up to have the rear sender work. The instruction to me was that the
fuel gage 1/2 tank reading was actually be a 1/4 tank. Now I seem to be running out of gas at just above 1/2 tank so plan on replacing the tank
selector valve, but in re-reading the info online on the subject I ran across this.
I'm having senders go out more frquently and with the crappy action of the new senders available, I have been opening up the senders, cleaning up the
windings of the resister coil resetting the tension on the wiper and checking connections on the terminal to make the old senders work again. Have
been pretty successful in getting at least one of the 2 senders working. In reality you only need one sender (preferrably in the rear tank) to work.
Both senders read the same fuel level until the tank with the sender goes below 1/4 tank. I would never run a coach below 1/4 tank-- they are too
heavy to push! If you watch the odometer and not go below 1/4 tank as much as possible, one good sender will do ya. On fuel injected coaches, I toe
a crossover between the drains of the tanks to allow sharing of fuel right to the bottom which actually negates the need for 2 senders. If the FI
system dumps it's pressure into the fill rail, you could draw one tank
totally dry without the lower crossover line.
I am wondering having this lower crossover hose to combine both tanks would be my best solution? I am hoping this will be so I can get a reliable
fuel level reading and use most of my fuel capacity. Seems to be a simple and slick solution to all this. If so then not seeing a need for fuel
selector valve?
Thanks,
Tom
