fuel tank venting w/perry regulated pump

[Ken Thompson III]

Verne,

The only problem with your setup, in my plane, I can't see my tank, its not on the CG, so without the open line to atmosphere, the overflow of a full tank can't go past the check valve, letting me know the tank is full.  I can fix that with double dots, one for overflow and one for fill.

  Ken,
  You've no doubt read some of the threads describing a tee in the line where one end goes to the tank vent, one end goes to the check valve, and one end goes to a fuel dot. That's what I'm doing. To fuel, you pull out the fuel dot which lets the tank vent act as a fuel overflow. when it's filled up, you put the dot back in. Pretty simple setup that works well as long as the check valve's pointing the right way.

    Verne,

    That settles it, I'm picking up check valves this week.  I wish this thread would have been posted last year, I could have saved a lot of Windex.

      Ken,
      The Smaragds you've seen me with the last two seasons both have a YS check valve on the vent line. The sole purpose is to prevent a mess if the vent line siphons. Never had any problems.

        Nat,
        With you and Bob P. using the check valve, I'm thinking that is the way I should be doing mine.  
        It's an easy addition.
        Ken

            i just installed a perry pump and the instructions say not to use muffler pressure to the tank. my question is, how do i vent the tank properly so i don't create a siphon from the vent line?
