I've accomplished a few things since my last post. I installed sound deadening material on the back wall of the cab in the Brat. I already had done the floor a few years ago when I put in new carpet, but decided now was the time for the back wall since I had the panel removed to access the fuel lines.
I decided to run a new fuel return line to replace the small and maybe inadequate stock one. So I used a tubing bender and made a new hard line in 5/16 to match the supply. It is quite crowded under the dash, but I was able to work it all under and around the pedals without too much trouble. Should have just done it when I had the dash out.
The new return line emerges into the engine bay.
Rather than pull the tank and braze a new 5/16 nipple on, I got one of those "retrofit" return line bungs where you drill a hole, and then by tightening a bolt, it smashes flat the inside to clamp it to the tank (think rivet) with an o ring to hopefully have a no drip seal. My thought was if it leaks, I have to pull the tank anyway and I could patch it if it was no good.
The new location for my filter/surge tank is just ahead of the passenger rear wheel.
The new location for my high pressure pump is right behind the stock "lift" pump that feeds my surge tank now.
I'm waiting for a few more feet of high pressure fuel line now to complete the runs under the hood, and then I'll be ready for a test drive!
