First is my plan was to run nylon psi braided line through conduit I installed inside my boxed frame rail, after doing some reading it appears that only metallic line can be use except for a 12" whip in either end. Am I interpreting this right? Second is it is stated the fuel cell has to be enclosed by the body, my cell is going under the bed floor in the rear. They also state the cell has to be protected by DOM tubing if it projects through the floor of the vehicle.

Can aluminum be used? And what gauge tube and metal is required? Also if I have my fuel lines I cases in conduit can they be braided? Thanks guys.

A couple of excerpts from online NHRA stuff. If the cell is plastic it must be covered with metal if outside the vehicle. Why not just use a metal fuel cell?

That is legal. Why not keep it inside the frame rails? No you are not interpreting this right, You can use braided line the whole way just not your nonstandard ie: not approved by NHRA stuff. It's really quite simple. If it does not look safe and close to what everyone else is doing you will get a finger wag. All fuel tanks must have a pressure cap and be vented outside of body.

Since I'm fresh out of NHRA rule books, can someone give me the quick low-down on fuel line requirements? From what I'm able to find, the overall rule is hard lines, with no more than inches of rubber line. This would be 6 inches from tank to hard line, 6 inches from hard line to fuel pump or 6-inches from frame to engine if an inline electric pump is employed.

Is there any specific rule that mandates braided metal line at a certain ET?

Thanks, -Brad. Tags: None. December 31st,AM. The way I understand it they count from the pump to the carb, since the rubber line from the hard line to the pump and the intermediate rubber line connecting back hard line and front hard line at least on a Nova came from the factory that way. They're just worried about the guy who puts on a new intake and carb and runs a rubber line from pump to carb. An easy way around the rule is to buy braided line and use hose clamps, no need for AN fittings, unless you're running something serious.
