Ok I heard of some guys running twin stock pumps in their NNBS trucks, does anyone have any information about this and how I can do this? I have searched with no luck. Thanks

 

I ran twin stockers. Original pump ran like normal, second pump was on a hobbs switch that came on around 5psi. Had to hack up the bucket to make it work.

 

I probably would run into the same problem with my fcpm wouldn't i

 

What problem?

 

Well like the problem when running a walbro it will burn it up

 

A walbro isn't a stock pump lol.. But if you tune out the variable fuel pressure settings, a walbro should do fine.

 

Lol I know that, but I'm thinking that adding an extra stock pump would get messed with from the fpcm, anyways you say tune it out?, if I add a couple walbros I can just pull the fuse and tune it out?

 

You don't add the second pump to the stock wiring, FPCMs cannot handle the extra current draw. It needs to be controlled independently. You don't tune out the FPCM, just the variable pressure settings. Set it to 58psi across the board and be done with it. Fuse needs to stay in to monitor fuel pressure.

 

Oh I get it now lol, didn't think about that stuff, so what do you think should I waste my time with twin stock pumps or just throw a walbro in there and get it tuned? I'm keeping it at least 9psi or under for awhile

 

A single walbro would handle that...consider about how many times you want to do the fuel system, though.
