Does anybody know the threadsize/pitch for the fuel screw lock nut? I think the size is 13 mm.

I lost mine last night when I was installing my new fuel screw. I borrowed my dads locknut for the time being. The plates on his truck are out of date, so he does not drive it, but I would like to have it back up as soon as I can.

Or if anybody has extra pump parts, help a brutha out?

 

Don't know the pitch or anything, but I'd just grab one from a junkyard.

 

what's the recommended way to remove the factory cap? while i've got my head off, i could give it a try and check on the pitch for you. i've got a metric tap and dye set with a pitch guage.

 

You just kind of pry it off, I think.

You got diesel trucks in your areas' junkyards? edit, you're lucky.

 

I am not sure about the size but I have been told the fuel screw is an odd metric pitch.

 

Must be a Canadian thing.

Upon further thought, you could remove the fuel screw and take it to a nut and bolt store and get the proper nut there. I don't think nut and bolt stores are a Canadian thing!

 

Use two screw drivers. Walk it back and forth. It'll come out....

 

Found it!
