Hi Guys

I fired up my secondary fuel pump for  the first time today and was met =
with what I didn=E2=80=99t expect.
Instead of seeing a blip in the fuel pressure, I had a 10psi increase =
and high current draw from the pump which blew its 10amp fuse.
I=E2=80=99ll up the fuse as its too low me thinks.

I used an old fuel regulator I had on a rail. It was of a Toyota 4AGE =
engine of about 135hp.
Seems like its not able to bypass enough fuel with both pumps running.

I think I need to install a higher power adjustable regulator.
What experience do you guys have with turning both pumps on =
simultaneously?

I=E2=80=99m putting a pressure switch in the circuit to turn on the =
backup pump if the fuel pressure drops below a preset level.

Appreciate your thoughts and experience.
