Just an added comment on the extended run fuel tank I fabricated that is quoted below. You need to have the 2000i fuel tank full to the brim before screwing the cap that goes to the AUX tank on tight. ANY air in the 2000i tank or fuel fine from the AUX tank and it may not work. I used the AUX tank as shown last summer after a bad storm and it worked great but all air had to be purged first. Also note when you connect up and prime the system you will most likely spill some gasoline down the side of the generator. NEVER do this with a hot engine and let any spilled fuel evaporate before starting the genny.
Thanks for all your comments and suggestions. Any comments on how to do this for a parallel unit. Should I dual feed from one tank or two separate tanks?
You know, the biggest problem with this set-up is the lack of significant vacuum being developed in the fuel tank to pull fuel from the aux tank. The ONLY thing you have that makes the vacuum is the gravitational fall of fuel for about 2" into the carburetor. I
suspect you would encounter problems using a T or Y and trying to feed twins from one tank. My knee jerk is probably not what you want to hear - use two independent aux tanks and feed lines.
If there was a fuel pump on the CPE unit sucking fuel it would be a lot simpler - but there is not. Upside is not having a pump means one less part in the system to fail.
A small-engine vacuum operated fuel pump like
this one connected to port vacuum on the 2000i engine between the tank and carb
should do no harm and would improve the performance of an aux tank. But, I have not tested this and it might void your CPE warranty. Another issue is developing a way to get port vacuum sufficient to run the pump. As built, there is no port vacuum access on the 2000i. My thinking is a 3/8" thick spacer added between the engine and carb with at least a 1/8" tube drilled in the center of one side to supply ported vacuum. It gets complicated, doesn't it? :h
