Running fuel lines in tunnel.
I put this in the engine section because it can be used with carb's, or fuel injection for any motor transplant (as long as the motor stays in the back) For my motor I needed to run two lines (feed and return for EFI)
This is 3/8" 304 SS .023 wall tubing with -6 AN SS fittings welded to the ends (not for the novice welder to attempt please) Each line was argon purged during welding and then pressure tested @90 psi. for 20 minutes each. This test was done after welding fittings on tube, and then again after welding fittings to frame. Some of the bends had to made AFTER the tube was installed in the tunnel. Mainly the ones at the bulk head as I fed mine in from the frame horn end. Also, important to secure the lines somewhere in the middle of the run (I used the old tab from the clutch tube I cut out) You will have to cut two holes big enough to work with in the passenger side of the tunnel to help with this modification.

Very nice, don't suppose you have ideas for alternative fittings that don't require the use of TIG? Otherwise my plan is to just put swages on the ends of the lines with tight fitting rubber glands where they come out at each end and a welded/bolted in bracket through the shifter hole to the side of the tunnel to hold them in place.

Ever heard of a company called SWAGELOK or PARKER HARRIFIN ??? They do loads of fittings right up to 30,000psi

I've used swagelock and Parker before at work, that fitting still looks like you need access inside the tunnel to tighten it up, ie a regular bulkhead fitting... Or are you suggesting I cut out the section to fit it and then weld it back in?
Pan should be rolling again today!

Ricola if using "bolt on" fittings you can have the line come out as much as you need for fittings. Then, just use rubber grommets where the line goes through the pan.
To use the bulkhead fitting's you would need to cut access panels that could be removed (bolt in, not welded) later if needed. Also, you would need access to put the nut on the backside of the bulkhead fitting. IMO wouldn't trust a mechanical connection sealed inside the tunnel. I would like the option to "check" the connections from time to time. (maybe I'm just paranoid )

I'm with you there, don't like the idea (strengthwise) of having a removable section so will probably just go with grommets.. I'm paranoid about stuff like that too!

I use them offshore in the oil and gas industry at pressures up to 10,000 Psi and if done right ( finger tight then 1 1/4 turns) you wont get any leaks for another 20 years
