    At the end of last year I purchased a Exmark Lazer Z EPS, with the 26hp EFI engine. My question is, is it more important to flip to the other tank before you run out of fuel, or is it ok to ocasionally run the tank dry, and have to let the fuel pump cycle to work the air out of the lines? Also what is the deal with the fuel tank selector switch, it is differnt than the ones on the regular carbrated engines,

    Thanks for the post. It's more important to switch the tanks and NOT run them empty. This really holds true for any engine and not just the EFI. If you run a tank dry you run the risk of plugging your fuel filters prematurely because the fuel pick up is forced to draw any sediment that may be in the tank.

    With the early EFI units they were extremely difficult to re-start if you ran them dry of fuel. In some cases the operator would then continue to crank the engine, hoping it would start. The continual cranking of the starter could cause premature wear of the starter.

    A lot of operators will run for a half day till say around noon and simply switch tanks so they won't need to worry about running out of fuel.
