I am thinking of buying the BD aux lift pump in conjunction with my intank (mfg warr) one. Anyone have any thoughts. I am not looking to push a ton of fuel. Maybe someday some mach 1.6s. Anybody have input on this decision.

 

I've been running the same set up for at least 1.5 yrs, 20psi at idle, and even with my mods have only been able to pull it down to 12psi at WOT.

 

where did you install the fuel pump was thinking of going that way but ive heard that the intank pump would be to slow to keep up with the pusher pump
thanks

 

I thought the in tank was not compatible with a pull type pump due to the open discharge of the in tank pump back to the tank. The idea being that the aux pump would pull air from this port pushing air through your system. That's why most setups like this are forced to use a "draw straw".

I know this is the usual recommended method of getting by the in tank pump. At least on the 2nd gen stuff like mine.

 

My BD kit worked well while I had it. Good fuel pressure with it for reasonable $. Bullydog also makes a nice kit. There are plenty of ways to configure a pusher system including making your own with a relay.

I pulled mine out when I put a cam in and the mechanical 12v lift pump. I wanted a truely bulletproof system.

 

Wow, I did not know about the air issue. Sounds like I better look at something other than an auxilllary pump. Maybe the airdog. Just dont like spending more than have to.

 

You won't have any trouble with it, mine works fine and i'm pushing 450-500rwhp.

 

i put one in about a year ago and its worked great i've had no problems with it at all
