Mine work great and I've never had a problem. When I spoke to Red 2 days ago he said he had sold 2000 double pumper set ups over the years. Can't be that bad of a concept.

2000 pumps! No, you can't go wrong with that.

I have a Red Arnstrong dp'r in my blue car. It moves a lot of fuel. His XP pumps alone move a lot of fuel. You will have to make sure your on point is correct for the second pump or the volume will be so great that it will overpower the regulator and fuel lines causing a really rich spot ill you get up to full boost. There is no need for this pump in anything under 500rwhp imo.

I have been running this set-up in my GN for about 8 years, no problems at all and they pump pleanty of fuel. Red is a smart ol' Geezer.

How'd you do that?
My second pump (factory setting) comes on at 10psi. I'd like it to come on at like 15psi

On back of the the valve that you have there where your vacumn connects there is a rubber plug take that out and adjust the set screw with a allen head. Clockwise to increase an opposite to decrease. I forget what that valve is called but it came with your kit!!

Guy's,

I know the hobbs switch that Red used on the early double pumpers wasn't adjustable and was set at 10 psi. On my system I changed out the hobbs switch for an adjustable one I got from NOS. I set my 2nd pump to come on at 17 psi.

Neal, you don't happen to have a part number for that hobbs switch do ya?
TIA

I find it hard to believe that after all these years red would not supply a adjustable hobb switch...to fine tune when the second pump would come on..Well i should know any day as i ordered one
