I currently run a fuel line, positive battery cable and ground cable on the outside of the right frame rail. I attached the fuel line with Adel cushion clamps pop riveted to the frame rail. The battery cables are zip tied with heavy duty ties that go around the frame rail. It's lasted for years but there's gotta be a better way. How is yours done?

Id use the same style clamps.

Just use two Adel clamps, at the same location, one pointed up, one down. Pop rivet is fine, but you could also tap for 10-32 and use screws.

I ran my battery cables in the car. My fuel line is like yours with screws.

You are looking for a better way, but if configuration limit you options, they make metal reinforced zip ties that might offer more confidence.

These are nicer.

And I thought I had a place saved that made double clamps with different size holes for each side. Still looking.

Ran my battery cable and fuel line inside my right rocker panel.

Did you run the cables up over the cage?

Good ideas here, thanks for the replies.

No my battery cables, pos and neg, run along the tunnel on the pass side.

I hope your screws are machine screws with threadlocker, not sheet metal screws or teks.
They do come out and end up in the pits,and on track.

Gawd, I hope they are physically seperated. Fuel and 800 amps or so will make a lot of smoke.

Does that mean attachment every 19" for aluminum and 23 for steel lines?

Great topic, Ron. I have mine fastened down exactly like yours on my GM A-Body.
This is something I have been meaning to ask about for a long time, (or at least take a look in the pits at what others have done).
Having a full frame car, I ran both fuel lines (supply and return), and battery cable inside my boxed right frame rail, from just behind the RF wheel, all the way back to where they exit it at the RR area under the trunk. Because I used existing openings in the rail, the rear exit is on the outside, and whenever I am under there, and see that 2/0 positive cable side by side with the fuel lines, my thoughts go to what Bad News said... Thinking if something got messy on the track, and the RR corner banged a wall with even moderate force, it could make for a real fireball.

The first time my car was texted at a nhra race after building it I was told to move the fuel lines to the motor/ trans side of frame. Was told you cannot have fuel lines in rocker panels or outside frame rails. The reason was to protect fuel line in case of a crash. I said I ran it outside to separate the line from the flexplate area in case flexplate broke. Was told nice try,go fix it or don't race.

I've seen that written that way in the rule book many years ago after I ran mine on the outside. I worried more about engine parts, trans parts or driveshaft parts hitting the fuel or brake lines so I ran everything outside. In the 70's we had to make sure the brake lines were outside the frame rail where in the clutch area for the same reason even though we had to have a blow shield. I'll have to see what obstacles there are on the inside.

Jim, I think Bad News is right about my inept way of running all that, but yours are well protected inside the rail. I'd be a little worried about the fuel line not being tied down especially if you have an aluminum line, which you most likely don't.

You would have just needed to run the fuel line through some steel tubing in the bellhousing area to conform.

Flopping around chafing the line or the cable, a crash which was previously mentioned which could shear the insulation and at the same time crush or break the fuel line, and with the fule pump under power big fire.
Fuel line......in my opinion should only be steel braided or Kevlar/steel braided. Aluminium is old school and dangerous, but cheap, and still sold. As is push lock.
And fuel and electrical should never be together. Dont ty wrap your battery cable to your secure fuel line or vice versa. Battery cable inside the car and fuel line outside the car.

My 2018 IHRA rule book doesn't say that the fuel lines have to be inside the frame. It does say that the line must be inside a 16" long steel pipe when it's in the flywheel area. The NHRA book says "...within the confines of the frame."
