I added an inline clear fuel filter and started having running problems. It ran well when the tank was full but the fuel pump was making noise. It ran poorly (lean) when the tank was near empty. I removed the filter and all is good! The filter never filled with fuel. You could see the fuel flow through the filter but not fill it. I put the filter in to prevent stuff from when the RV was built getting to the gennie. Plus extend the life of the onan oe filter which is kind of hard to get to and rather expensive.
Wow, interesting. Mine will run fine through the filter with the line in a can of gas, but sounds very similar to my issues. It looked like the filter always had air in it, but would fill enough to work. The fuel coming out of the line would kind of sputter and splash into the filter. As the generator ran with a load, it would use fuel faster than it was coming in. I thought that it was sucking an air/fuel mix from the tank. I initially added the inline filter because my generator compartment is rather small and I absolutely can not change the Onan filter without removing the exhaust, unbolting the entire generator, and moving it sideways enough to get clearance. Not exactly something I can do at midnight in the middle of nowhere when the Onan filter decides to clog up. Since it's free, I will install the new pickup tube and put it back together. If it still acts up, I will remove the clear filter and try it again. If that is what mine is doing too, I am going to look at adding an inline electric pump. With the way my generator is enclosed, I cannot take the chance of the Onan filter clogging while we are camping.
