OK, my posts getting published now Thank you.
Have seen all above problems with E10 fuel here in CA. In this 420 fuel system, the Olefins turning to molasses did in the fuel pump. This system with two fuel filters you cannot see is stupid. And, the fuel pump in a separate canister with filter at bottom on original design ?? even dumber, (new one now on the side ).
Best modification I am doing now is putting a drain in that canister. If you look at it, someone cast a "boss" into it for such a drain then it was never done??? Since it is lowest point in system, water, etc. easy drain out. With new pump apart, I drilled and threaded it for a 1/8" NPT and waiting on a Curtis drain petcock with O ring fit for E10 fuels. Why fuel ate up the "screen" material on the tank pickup filter? = Bad choice of material.
Why not just use stainless steel mesh like most every system I've seen before?
Going to try new Chevron small engine fuel treatment, stabilize for 2 yrs. Since I use Chevron only, would think their chemists know their fuel the best.. Have used Sta-Bil for years, but think will try this newer product now. Looks suspiciously like Sta-Bil 360?
