The guage can work fine even if the LP isn't getting power.

Picked up a new OPS and socket this morning. Changed the OPS out and the truck started right up and dint smoke like it used to. Took it for a ride to get it warmed up. Gonna start it after it sets for a little while. Hopefully this takes care if it. Still bought a lift pump in case.

Hope you bought ac delco parts

X2 on the AC/DELCO parts made that mistake a few years ago installed a BWD brand OPS and less than 20 miles on it the top popped off shooting oil everywhere under the hood.

Mines from Napa, I'm gonna get a Delco sometime next week, they didn't have any in stock and I wanted one right now. Are the OPS's from SS Diesel any good? Was going to order a few things and thought about getting one.

Napa will work have a Napa LP going on 3 under my rig.

The aftermarket OPS might last a while?
No matter what switch you use you should google OPS relay mod and install it for long term reliability or buy the kit from Kennedy Diesel.

I personally don't deal with SS Diesel-wayy too many reports of no service after the sale or rude/ignorant contacts when problems are addressed-many dissatisfied customers treated poorly when warranty is required.

Best advice on vendors is use site sponsors here.
