Hello folks, it has been awhile since I posted. I currently have a fass pump and 275 inj, with comp. When I put the pedal down with the comp ome tow or 2, I go to 0 fuel pressure. I need some input on the mechanical drive, as I may purchase one.
Thanks,
Geer

 

i have the MITUSA pump. much simpler than the fuel boss, but same premise. it just doesn't keep the stock LP as backup . . .

it works great, fuel pressure goes up when hammering down. i don't regret it at all.

 

There's not a lot, but a few guys with mech. L.P.'s on here

I'm runnin a FB and it's aweomse. Like Doj said, the fuel boss does keep the stock LP intact and functional. If in case you lose a belt or somethin there is a pressure switch that kicks the stocker in so you dont run w/o f.p. I'm seeing 16-17 @ idle, and never seen it drop below 14 psi. Cruising at 18-19 psi. Although I just put in a VP, so my wire isnt tapped yet, and just added 100hp sticks, that may change things. But when I was running strictly the Juice w/ it tapped, those are the numbers I was seeing.

Installing is easy, and if there's any problems you can call Glacier, great guys to deal with, very helpful with my install.

 

Nick02ram, thank you. I have been tapped since 02, and replaced 1 vp. I think I will order one, as when I put the foot down I go to zero in seconds.

 

I have the fuel boss and is set up like the mitusa. I do NOT have the stock or any other electric fuel pump. The lowest FP I see is 15 and 20 at WOT.

 

Geer, something doesn't seem right--what kind of FASS do you have? I have an old FASS 150 with an Edge Comp and bigger injectors than you and at full throttle my fuel pressure only drops maybe 1 psi, from a steady 16 - 17 at idle.

 

Well I have the FASS 150 too, and I can not stay in it. I wonder if the pump is faulty, it has been in for a couple of years, but done it from day one.

Who'd you buy it from? You might give them a call. A lot of places will send you replacement springs and other small replacement items for free. At the very least they should be able to easily help you diagnose what's going on.
