: Hope I got it all for you. If not, let me know.
Couple of things. I have the rear axle lines and long line for dual exhaust. This in effect moves the flexible hose away from the exhaust pipe so it may look different then yours.
If you're considering replacing your tank to pump fuel line, now would be a good time since they share the same brackets in the tunnel.
First 3 pics are of the firewall. 4th & 5th pic are the tunnel and the brackets. 6th pic is where the lines make the turn near the front of the tunnel. I added those brackets. I wanted to snug the lines up closer to the floor pan. 7th pic is where the flexible line from the rear axle meets the long line. Ignore the hokey bracket I made. I did that before I realized that you can buy a ready made one for $5.
Pics 8-10 are different views of the rear axle and how the connections are made to the junction block. Good Luck.
Let us know how you make out.
