Chuckd84,
The push lock fitting at your tank control module converting to PTFE -an6 should have a hose clamp.
The rubber fuel lines there should be Gates Barricade, rated to 300 PSI. Gates Hose has green writing on it and it is reinforced for TPI/TBI pressures.
You are pushing 42-65 psi with modern fuel injection. Use the correct hose, valves and clamps.
Stay away from push lock, especially without clamps.
Push lock is basically rated for 7 psi carburator use.
Anyone who chimes in and says push lock is rated for TPI is wrong.
Most of the older carburated small blocks with dual tanks have cross over plumbing and control valves rated for 7 psi fuel systems.
You should not mix and match old school fuel systems when upgrading to the FiTech system.
The Holley EFI TPI/TBI tank sending units with the -an fittings are expensive because they work safely.
Converting from push lock to high pressure -an hose is sketchy.
If that hose gets warm near the exhaust, that push lock will fall right off and cause a problem.
Are you positive that tank valve in your video is rated for TPI pressures?
What happens if you kick up a rock and that tank transfer valve breaks one of those plastic ports?
Fire is what happens.
My thought would be to build a manual valve out of aluminum manifold, for tank swapping.
Get the elctronics and that plastic valve assembly out of the system entirely.
You can thread for the -an fittings and avoid the rubber lines.
It only takes a minute to crawl under and turn a valve between tanks, if you need to.
The Earl's ball valves are $70 for a reason.
I use pex style stainless ring crimp clamps for fuel Gates Barricade TBI/TPI fuel lines, with a pex crimper. The stainless steel screw style fuel line clamps in your video work ok, so long as you keep up on them and do not allow them to rust out. My issue with the screw clamps you are using, is the quality has gone way down on them. The blue steel pot metal they are using is crap. I cannot find any made in the USA amymore, anywhere.
You would think such an important thing such as fuel line screw clamps would still be made in USA?
I'm not criticizing to be rude. Use the correct hose and design the system with safety in mind.
Click on my sig and research my posts for fuel line system threads.
Your frame is very clean. Nice rig!
Do not cut corners and accidentally burn it up.
