when i hook up my air dog 150 do i need to plug in the electrical connecter on the old lift pump? im assuming that runs fule guage. any help is appricieated.

 

Did you have a lift pump on the block or in tank. The one on the tank is for fuel level. The connection for a block mounted pump should activate the relay for the AD

 

there is a pump on the bolck that plugs into the ad harness so yes i do need to plug in the one in the tank

 

Yes, that's for you fuel level sending unit

 

thanks fellas

 

well got the air dog all hooked up and the truck wont start. bled the lines and nothing hooked the foctory lift pump back and she fires rite up. any ideas fellas?

 

Can you hear the Airdog running?

 

ya but hardly any fule comes out of the line

also it dont seem as loud as others iv herd. the guy i bought it from said the pump is bad. it realy bums me out to spend all that money and get bad parts!

 

I had a similiar problem with mine it didnt sound like the pump was pulling any fuel. Cracked injector lines, let the pump prime, and still nothin. Turned out that i had the pick up line pinched between the tank and bed Try checkin over your lines again.

 

did all that and checked all the lines they are not kinked any where.
