Ebay HD OPS?

Anybody heard of a HD OPS? I didn't know if GM had ever upgraded this part. The price is very similar to the local Advance Auto for a Delco part.

If your present OPS has not failed consider the OPS mode and extend the life of your switch.
Look at my web page for details on the rewiring.

HowieE - makes a lot of sense. Are you using the same type of fuel pump relay that came on these trucks or some other common part?

The relay is a standard 30 amp auto relay that most auto suppliers should have for about $6.00.
If you can not find one then check with Bully Dog.
