I have used a "Carter" and an "Airtek" and neither seemed to last very long. Put them in they work come back a few days/a week later nothing. Pull tank and pump again and "flick" the impellor and it runs, try again it runs, as many times as I try! Put same pump back in, run out of time, get back to it later, and it will not go, repeat! Now I've installed a "Delphi" and it comes out of storage soon and I can update. The pumps were covered in a white scale after dis-assembly, I am presuming from the "Alcohol Laced Gas" This time I will add some Sta-Bil for Alcohol supplemented fuels when it gets filled up. Here are the two I am thinking of.
