[Fot] TR6 race car re-build - Fuel line questions

[Mike Harmuth]

Mark, here's a link to a chart that specs out what size fuel line to run
based on things like HP and fuel type.

I run metal braided lines (AN) fitting type in the trunk and under the
bonnet (with bulkhead fittings) and metal lines in the cockpit, Fuel reg
with gauge in the engine bay where I can see what's getting delivered at
the engine.
