I finished installing the Holley combination sending unit/fuel injection (model # 12-319) which is for 63-76 A bodies to ny reproduction gas tank. The install was fairly straightforward - Holley uses a porous mat called a HydraMat which provides fuel to the pump in low fuel situations (the yellowish thing on the far right). It is installed to the inlet fitting at the bottom of the fuel pump. Then per the instructions the sending unit/float assembly is removed from its bracket on the fuel line tube to facilitate installation. The mat is installed first followed by the pump. Then the sending unit is re-attached to it’s mounting bracket and fed into the opening. After installing the gasket to seal the unit, then the lock ring gets installed. The wiring is straightforward with the pump ground to the battery, another ground for the sending unit, a wire to the gas gauge, and a power wire to a Bosch-style relay which is (user supplied). Holley Tech Support recommends using the Sniper’s built in relay to trigger the fuel pump relay.

Today was tank install day so got my buddy to stop by since he’d volunteered to assist in the installation.

Tank was almost ready to hoist in place after the new tank seal installed. I nearly forgot to install some tank to floor cushioning.

With the tar paper cushion glued on, the tank is now ready to install

The new floor seal from DMT needs to be slid on the filler pipe prior to installing the filler pipe into the tank. With a little WD40at the tank seal, the pipe sort of slid on in (it was definitely a 2 person job working with the filler pipe and jockeying the tank around at the same time! I need the proper size stainless steel screws to secure the floor seal.

Not shown is the filler pipe to quarter panel seal - also from DMT. Until i can get the right size stainless steel screws, i used a couple of regular screws to secure the filler pipe flange to the quarter panel

With the filler tube installed, it appears there’s some kind of plate or seal that is mounted on the inside. there are screw holes so something must go there! I don’t recall removing one. Anyone following this build who has a wagon (@65dartcharger ) have any pics of what I’m missing? There is a wagon in a junkyard about 40 mikes from here that hopefully has this missing part!
