Yeah, I understand the allure of staying mechanical. If your fuel system is in good shape otherwise, sure try to upgrade your pump. But if a car is like most of these when restorations start, with a tank or lines that need to be replaced anyway. There is just no good reason to not go in tank.


Though to be fair, my issues really only showed up on the track. That and slow starting after it sat for a week. Even with the electric I still get more drainback than I feel like I should. If it sits for a few days, I can hear the pump fill the lines when I turn the key on.

The swap overall went well for me. Converting the Robb regulator was a breeze, only had to run one line. I do need to bend my big 1/2 stainless feed line in one place. Currently because of its location I get a kink in the soft line on the way to the regulator. I got to eliminate about 8 feet of hose in the front of the car because the mechanical pump is on the opposite side of the fuel lines in a first gen Bird. Relay in the engine bay with only one big wire running back to the pump. If it wasn't so damned hot out it would have been even easier.

One place I got lazy was the power wire for the pump, I ran it under the car. In the future Ill probably run that inside. I did at least cover it in snakeskin for mechanical protection. I also may have to drop the tank and replace the seal. Im going to put it on a hill and let all the gas run to the front and see whats up.
