No fuel pressure at gauge. Pulled suction line off and put it in gallon jug of fuel.Pump runs but 0 output. put on new Holley blue pump on frame rail running thru stock filter housing. 12 psi at idle 9 at wot. seems like enough fuel since vp 44 has 14 psi bypass. Are fass pumps rebuildable? It's a 150 with brand new filters.

 

warranty work 4 years or have you had it more

 

you probably got the lines hooked up wrong. i did that when i first installled mine.

 

The fass was on the truck when I got it. It worked ok until my fuel gelled. I put new filters on it then. tested pump and got no suction on pickup side of pump and no output. vp 44 will most definitely run on 0 pressure. good thing I checked cause it probably would'nt last long! Running Holley blue now.OK so far.

 

Does that warranty only cover original owner? Is there a build date on pump?

 

Dont know how i missed this one....SO whats going on?

 

Thanks for the info Dan. I`ll check the serial numbers and go from there. I bought the truck used with the Fass already installed. Guys who think their Fass pump is loud should hear a Holley blue pump mounted with rubber insulator to the frame rail!

 

My holley is quieter than any fass system I've ever heard.

 

Shoot me an SN and we will see what we can do. This will give me all the info I need to see what the pump is and how old it is. The 6 year wnty is good for the original purchaser of the unit. BUT the unit comes with a 1 year initial wnty from the build date.
