Is there a way I can check to see if my pump has been pin timed to something other than factory? I purchased a pump a long while back that supposedly had some work done to it and I’m just unsure that everything is working as it should. Any help would be great!
 
I'd just install it assuming it's still stock at 12'sh degrees, set it where you want. If it's off you'll hear it.
 
Look at power driven diesel timing kit. To see if pump is at factory timing pin the cam gear and than see if you can pin the pump. If you can whatever stock time is usually 12 or 14 depending what pump. I’d bump it to 16-20 range for some extra power and they usually burn cleaner in that ranger lowers egts too.
The prices of pinning it is wayyy cheaper and easier the the indicator method and is harder to mess up.

This. Grab a power driven kit or just do the math yourself and turn your motor over accordingly. Always assume 12-14 degrees is pin timing. Plenty of youtube videos explaining it further

Already looked into the timing light. That will be the most accurate way. I can pin time the pump all day long. That doesn’t tell me what the pump was set at by the mystery builder 10 years ago...
 
Are the timing lights that accurate ? If so I might invest in one.

Not to hijack the tread but say I wanted to add as much timing as my 95 would like. Would I just keep advancing it until it wouldn’t build boost on the line and then back it down or what ?
 
Use the dial indicator like you would be setting the timing on the truck. Run it to base circle zero the gauge and then turn the pump to the pin spot. Read gauge and find the chart to tell you what lift is what timing.

I have an adjustable pump gear, started at 30 and advanced it 2* at a time. 36 is what it ran its best at.
At 38 it still spooled up easy, but ran slower.
Another truck that was similar to mine at the time also settled on 36, acted the same.

On a daily? What kind of hp numbers are you looking at? PDD’s competition 12V that just put down 2800 HP is around 40 degrees of timing .....

Its a drag truck, just a basic old 12v. Runs high 9's
Its just what that setup liked best, anything over 36 and it falls off.
Another buddy of mine with a similiar setup when he ran a 5.9 12v, his truck acted the exact same, ran slower over 36*
