35" 05 I have the bd pump on my and it been pretty good so far my fuel pressure runs at 25 psi and when I get on it drop to 19 psi. Others buddy have the fass system it runs good to but my has a few more psi then them.

I have the BD Aux Lift Pump Kit and it runs good and it's not noise at all, plus the price is excellent at $254. I can say anything about the customer support, because like I said, the pump runs good.

All you guys with 03, 04 with the lift pump on the fuel filter. and you replaced it and it still works, please PM me, I'd like to pick up a spare. this is real, if it still works, maybe low fuel pressure, I'll pay the freight. I'd even pay the freight on a broken one just so I could that it apart and so why they are crap. I'm not trying to offend anyone, but there must be a reason why some only last 10,000 and some last 200,000 miles.

At what point, as far as added HP, do you need one one these? Thanks.

in my opinion anything more then stock

I'm also very happy with my bd set up 23psi at idle never falls lower then 18psi,been on my truck for over two years now and still works great

Rich2500, in my opinion, 99's through 02's need them stock! Guages are a must when adding HP. With a fuel pressure guage installed, you can watch your pressure and determine when it would be an appropriate time to install this type of set up. I personally would install guages and and some sort of pusher pump before any other type of modification.

in my 2005 i added the edge juice and i could just feel that when i was at WOT the engine would kinda fall off i installed my pump and it seems not to have this problem any longer and at highway speeds it seems to take less effort for it to keep up speed

I was reading another thread about how loud the FASS pump is. Can anyone vouch for how loud a glacier or walbro is.

PM me, I just took mine off last week and installed my Walbro 392.

my walbro 392 its more like what walbro 392? i can't hear it in the cab you can't even hear it standing next to the truck. we had to put our heads under the truck just to hear if it was running or not. this pump is quite!!
