Thanks for the responses guys. I'm planning to run a 100 micron unit prior to the pump and a 40 micron after prior to the carb. RobbMc suggested this setup. I just got to thinking about having to service that tank filter and though what a complete pain in the arse that could be without some way to shut the fuel off since the tank is now sumped and will dump fuel everywhere.
I could look and see if there is an easy way to get the fuel line inside the frame, there well may be...however, it might be a challenge to get the 52 years of mud and rocks vacuumed out enough to make room.
I'm not convinced 1/8" tubing would be very effective for shielding a flywheel explosion as they require...last flywheel I saw blow up it nearly cut the firewall completely off the car and the driver miraculously only got one chunk in his right ankle.
The SCTA rules for Bonneville are somewhat similar to NHRA. My 130mph class has these rules spelled out:
- On non OEM fuel delivery systems dual throttle return springs are required, on each throttle shaft.
- All non OEM fuel lines must be constructed of rubber, braided, or steel hard line. No aluminum/copper hard line or clear plastic hose will be allowed.
- Fuel lines are not allowed in the drivers compartment.
- On unibody cars such as Corvair, VW, Porsche, Etc. the fuel lines must be higher than the lowest part of the pan or the unibody structure. They must also be installed inside of a heavy metal tube or above a skid plate. The metal tube or skid plate must be positively attached (no sheet metal screws will be allowed). This is to protect the fuel system from damage if a wheel/tire failure should occur.[/i]
So I think I'm ok running the fuel line inside the frame rail. I'll see how easy it would be to do that with a fish tape, if not the backup could be to run it along side the old fuel line using it as a hanger with zip ties in addition to fastening it to the frame with the rubber insulated clamps every foot or two.
