G'day,

I intend to install low pressure in-tank pumps (7 psi) to feed a surge tank up front which can feed the mechanical fuel pump or a
high pressure FI pump. The surge tank will have a return plumbed into the 1/2 inch vent tube for the fuel filler.

1) cut off the tubes off a defective tank sender
2) drill a hole in the center of the tank sender
3) put a screw with a sharpened end through the hole and install in the tank(s)
4) raise the tank(s) into position
5) the screw will put a mark on the aluminum sheet that covers the Styrofoam insulation
6) drill a 1/8 inch hole up through the aluminum sheet, Styrofoam, and plywood floor
7) using the 1/8 inch hole as a guide cut a 6 inch hole using a fly cutter
8) using a router along the edge of the 6 inch hole create a step for a 1 inch thick plug with a stepped edge
9) cover the floor with high grade vinyl
10) carefully cut out the 6 inch hole in the vinyl and glue it to the plug
10) make a custom fit carpet to cover the area and bind the edges

This will provide access to the pumps should they require replacement.

Regards,
Rob M.

i agree in-tank pumps are both harder to install, and harder to change. But when you talk to those that went that route it seems
vapor lock is gone.

There are trade off's to all systems. A person has to make up there own mind and live with it.
