I need to know the Stock Fuel Line Size ASAP. I have a 2001 Dodge 24V Diesel and I'm ordering some stuff but wanna make sure it's the right size. Thanks all

 

stock fuel line size for 98.5 to 2004 is 1/2 inch

 

Actually it's 3/8''

 

3/8" supply and 5/16" return

Best option here is a big line kit from Vulcan Performance which converts the line to 1/2". This kit also eliminates the restrictive Banjo Bolts:

sorry for the wrong size there insane domestics must of read it wrong

 

No big deal Arizona. I don't really care about upgrading to 1/2 but I would like to know more about these Banjo Bolts. What are they and if they are restrictive how can I get rid of them without upgrading the line size. Sorry bout the Newb Questions, this is the first Diesel I've actually owned.

 

Banjo bolts essentially are fittings for the fuel system. Im guessing, but every aftermarket fuel system replaces them as they are restrictive:
