I have seen a rash of issues with the pulse-pumps used by all the mfr's..
Briggs, Kohler, Honda,.. they all use the black plasic fuel pump,
or the aluminum Mikuni vers.
Just to complicate things, the Vanguards have a "mystery-quirk" where one in 10 won't hardly operate a pulse pump at all.
..very strange ! .. but I will get to the bottom of that.
So, I'll say this..
Lifting the fuel more than 2 ft is questionable, but with 3/8" line, 10 feet away is no big deeal.
If you have to lift 2 ft or more, just go to an electric fuel pump, and be done with it.
