C15 primer plunger

I noticed my primer plunger on my C15 was sticking out. Almost looks like the threads to "lock" it down have worn out and it pops back up after driving for a while. Is this a quick easy replacement? I only see two bolts that hold it down to the filter housing. Is it just a remove the 2 bolts, slap the new one on, give it a few pumps, crank it up and go? Looks like someone has taken it off before.

I just bungeed it down for now... ok to run like that till next time I swing through the house?

 

Does it affect anything negatively? Previous owner put it on the truck. I know they are a gimmick and don't do a thing, but does it actually hurt anything to leave it in place?

 

I think I saw a link to that video but it was no longer available. I found a thread that mentioned it here on the forum, part number 6N-4414 I believe. How do you prime after changing the fuel filter then? Remove the plate, fill it with fuel, then just crank a bit until it fires? Looks like the primer pumps are notorious for sucking air anyway, so maybe I'm just best off replacing it with that plate for now until I can get a FASS setup.

 

I guess I'll keep the plunger around and throw it in the side box just in case I have a need to prime in the future and I can swap it out. Looks like the price for that plate is <$15 so I'll just grab one of those from Gregory Poole next time I'm at home. Thanks.
