Is the braided fuel hose for nitrous kits (usually 4an) have a rubber lining as opposed to the nitrous teflon coated hoses?
I am thinking of making my own 4an hose so i can make exact lengths i need for a neat fit. The hose i would buy is 4an braided with rubber inside liner. Just want to make sure its the same inner diameter as pre-man fuel lines for nitrous kits.

Thanks

 

teflon coated hoses are need on the Nitrous side, as far as on the fuel side rubber should be just fine. now the inner diameter is not the same as a teflon hose, but that should be ok on the fuel side (only)..
Good Luck, post some pics after its all done.

 

It looks like both red and blue braded hoses are typically teflon lined. I assume a 4an braided hose is just overall bigger in diameter? Should flow the same and have same inner diameter coorect?

 

You can order exactly what you want color fitings length etc from Nitrous Outlet they will custom make what you want cheap. If they dont have what you are looking for I got all black lines with black fitings makes for a stock look from HSW.

 

Ya thats where i have been ordering and have more to order. I dont know my lengths exactly being my car is in a different town, thats why I will custom make these short ones.
