Thanks Jeremy...

 

To trigger it, I am using an oil pressure switch (reliable) screwed directly into the intake manifold. When boost goes over 5 psi, it triggers the switch, which closes a relay that feeds power to the pump. I have a power wire running back just for the 2nd pump.

 

Thanks Mike.

 

Purchased fule pumps from Summit. I think $125 each. Fabricated the pump mount onto the existing sock assembly, and, a new bulkhead plate for two (2) fuel lines. No electrical trigger for pump #2. You need a good return circuit from the fuel regulator. This is working for me. Purchased bulkhead -6an fittings from Summit. Used Aeroquip socketless hose. All you need is a mig welder. Cut a hole in the rear pan for tank access.
