does anyone know the exact inside diameter of the stock feed line on a 94-up integra?i am not able to look at it right now and need to know.

 

Not sure how exact of an answer you're looking for, but a 5/16 " hose barb inserted into the fuel line will be a snug fit...

 

hmmmm 3/8.??? just guessing its a pretty standard size

hth

 

ttt

 

hondas use 5/16 fuel line on the pressure side.

 

Any ideas on what some of the higher hp cars (500ish hp) run for fuel line size? I was going to mount my fuel pump in the engine bay and needed some advice for the feed and pressure side size.
thanks.

 

Where do you route the lines if your upgrading your fuel lines to larger stainless steel braided lines? does the same go for nitrous lines? anyone done it? pics?

 

higher hp cars mount external pumps generally under the rear of the car somewhere... and ussually -10 an lines are used and are routed somehow undernieth the car... everyone does it a little differant... cant see mine!

 

the stock fuel line is 3/8" while the return line is 5/16"

 

im going to be running -10 AN feed and -6 AN for the return. Dublo, I have an SX fuel pump off my friends race car for sale. In operation for less than 20 miles total. We are going to let it go for a real good price. let me know if your interested.

 

Where can you get these lines (-10 AN , -6 AN)??

 

you have to order it from summit and assemble it yourself. getting the lines isnt the problem, its custom fabricating things to fit that cost expensive. a complete fuel system done with AN lines and associated hardware starts @ $1100 and up parts only.

 

-10 seems a little extreme. -8 would be more then enough.

 

-10 is simpler since it comes out the pump / filter that way.
