you know the main fuel line? where it screws into a rubber hose, then about a foot later, screws back into the steel line? well what size is that rubber hose?

reason i ask is i need to cut that hose, install a t fitting that will run to my 1/8" inlet on my fuel solenoid.

 

Should either be 3/8 or 5/16. You should have one size of each. Inlet and outlet lines.

 

stick a wrench over it and you'll know

 

is it measured by outside diameter?

 

The hose is measured by inside diameter. The two metal lines are 3/8" for pressure and 5/16" for return.

 

hard line would be measured by the od soft lines by the id

 

if the metal lines are 3/8" (the one to feed the TBI) is that what size the rubber hose part is as well?

 

i checked the nos website, and they only have a t fitting for 5/16"

would i be able to pick up a 3/8" 3/8" 1/8" tee fitting?

look someplace that deals in hydrolics, like parker store. you can pretty much get the parts and fittings to do anything you want.
