These worked out awesome. I suggest that you give them a try. Iโve had a lot of good luck with them. Thanks a lot for making these Patrick.

Works as it should! I used to jump the fuel pump with the key off on my 4.0L jeep. I had a fuel pressure problem where the regulator would bleed pressure off. This allowed me to hook up a gauge, turn the fuel pump on which should bring it to 29-31 psi and hold it in the rail. The regulator would not, as the o-rings bypassed fuel to return. This relay set helped me figure that out. Sure I could have just used a piece of wire to jump it, but a toggle is nice to have.

I've used these in the field to diagnose electrical issues more than I'd like to admit to. Works every time.
