Does anyone know the interior dia. of the stock fuel lines on an "00" 2500?

 

Bout 1/4". Give or take an 1/8".

 

Ummmm... I was kinda hoping for a more difinitive answer. I will be tapping into the existing line (for now) to put a pusher pump on and I need to figure out the size of the barb on the fittings I will need.

 

Theres a big diff. between 3/8" and 1/8" there hand...lol.........I come to expect these responses from him since he does go to ATM.

Tengu, im sure someone that knows the size will chime in here in a little while.

 

5/16"ID return, 3/8"ID intake

 

Thanks a bunch Infidel.
