AWESOME thanks. I guess the only thing better than that write up would be if the guy came to my house and installed it.

Just one question, what kind of relay is it?

 

There is another version that uses 2 relays to add a prime function and take more strain off the OPS:
Diesel Place : Chevrolet and GMC Diesel Truck Forums - View Single Post - OPS wiring 6.5 TD

 

I got the relay info - had to read in a few pages.

Question - How would the double relay set up take more strain off of the OPS. I'm thinking it would just make it start quicker since the LP would be priming during the GP cycle. So wouldn't the OPS still be taking over the LP function duties after the oil pressure is built up and the key is toggled back to the run position? It just seems like a useless mod as far as protecting the OPS...but I do see where it may be helpful for a quicker start. Am I missing something?

Thanks again for all your help racer55.

 

Correct,I needed to look at the diagram again to remember how it works.

Single relay mod is all that is required to take the load off the OPS.

 

Jumped the LP to run constantly. Performance is much much better. No stumbling or hesitating any more. The only thing I need to know is if it is normal for the LP to have a slight tapping sound when it is running. It sounds like one of the impeller blades might be hitting the inside of the pump somewhere. Idont have a real heavy wire supplying the LP circuit so could it still be running less than optimally?

One benefit I noticed was an increase of about 3 MPG with the LP running all the time.

 

Did you jump the stock relay or make the relay mod for the OPS?
The OPS is a safety factor in case of an accident to prevent fuel from being pumped all over the place making a fire hazard.
