I'm on my way to summit so if anyone could get back to me quick I am trying to figure out what t fitting I will need for my fuel pressure gauge I have a raptor 100 I don't know what size those lines are. After the filter the lines are stock so I'm not sure why I am buying.

 

1/2 fuel lines with the raptor. You really need to put your pressure gauge at the inlet of the IP. Change out the stock fuel lines from the stock filter housing to the IP with 1/2 line and push lock fittings.
