There are two popular ways of doing it.

1.) Run two pumps into two seperate lines and attach one to each fuel rail. Then use a single regulator and single return line. This requires putting a fitting in the sending unit to exit the second line from the tank.

2.) Run two pumps into a "Y" fitting and run a single supply line to the rails.

Either way you'll need to put a hole in the sending unit for the aditional electrical power for the second pump. JB weld works great for sealing those holes. You'll have to put a power relay in the power path and tie to to a key on power or perhaps a hobbs switch to turn on at a certain boost level.


I believe some Grand National places sell the "Y" fitting. Personally it was easier for me to run a second -6an line to the front of my car.


If you are worried about how to attach the pump, I just used two worm gear clamps and clamped the pumps together. Seems to be working great so far.

The 2nd pump will need to angle a little because the factory sum tank will not clear it that was my experience. Here is some pics of my twin setup yrs ago. The pic shown I tied the 2 pumps together but I have to untie it because of the angle is needed to clear the sum tank
Do not run both pump full time because 2 (255lph) this suckers will emptied the your reserved gas rather quickly and will get you stranged on the road.

Has anyone wired a second external activated by a hobbs switch? T rex pumps are a dime a dozen and I already have the heavy wiring to the external.

Also, blowerworks has a dual intank kit for like $129. I don't know any specifics but I did notice it this week when I was checking the fuel pump charts on their website.

I don't think that includes 2 pumps.

I don't think so either. I believe it's the add on pump and the mounting hardware (y block, ect).

I'm going the inline pump route - I purchased the inline pump from Greg at Blowerworks, it mounts behind the number plate. I understand people have had good results with this set-up.

What I want to do is run a walbro along with my stock pump but I would like to run it of the stock wireing at least the stock trigger wire.
I wounder if I can just splice into the stock trigger wire in front of the stock relay and use that to trigger both relays.
