Even a 100 gph pump will suck the canister dry if you don't plumb the AD return back to the canister, that is the problem I had until I did my mod.

The problem with hooking a 150 up to the factory feed is there's a restriction in the plastic where it comes up to the lid and makes the 90 which is only about ¼" which is way to small for a 150 pump.

Hope you get it figured out without spending anymore cash.

 

i wont spend anymore. they either have to do it 4 free or i will do it on the gravel road outside

 

Me myself, im not too happy with their pumps... a good friend of mine went through 3 in a few months, and mine just went a couple months ago... i dont know what it is, but to me, its more hassle than they're worth.. So far, ive only heard of one Air Dog to go bad.. so i went with airdog this time.. so far, so good.. they both have warranties but that doesnt cover the time, effort, or money it takes to install them..
