Those fuel pumps are just no good, they work for maybe 3 or 4 outings and then poof they take a poop and it's 10 to 12 buck's a pop, Do like I did and get you a Dave Brown "Six Shooter", they make 2,,One is for glow and the other is for gasoline, After 2 of those other nasty money drain pumps, I got a Dave brown six shooter pump and it's been doing it's thing for 6 years now, The other day I broke off the tubing fitting, no problem I just tapped threads for a 6-32 pressure or fuel fitting (Super Tigre $1.49 Tower # LXFX78) and no worries and fixed tubing fitting..Tower has what I mentioned, Just type in Dave Brown Fuel Pumps in the search bar and it will come up, note also that the DB pumps are slower that what you've been using but guarantee on my testimony you will never wear one out....greengoose...
