Pump Installation
To address the noise and vibration, the pumps were mounted using rubber washers, 1 inch diameter and eighth inch thick, with matching steel washers, on both sides. Fittings compatible with the black fabric covered fuel line and vintage style clamps were used to match the carburetor plumbing. Where possible aluminum tubing was used to span longer or less accessible locations.
The aluminum tubing ends were treated with a bead tool to assure the hose and clamps would stay in place. This tool is available from several sources including Pegasus.
The fuel line goes directly from the tank to the input of the pump. No separate filter is needed, since it is integral with the pump. This eliminates another pair of connections on both sides.
An aluminum fuel line was used to carry the fuel from the right fuel pump, along the base of the firewall opening, to the regulator on the left side. It was covered with insulating material. This line was connected to the pump on the right and the regulator on the left side with lengths of 3/8” I.D. fuel line.
Clearance issues required a bit of trimming. Small sections of fiberglass had to be cut away on the inside of the rear clip to clear the top of the right pump.
