01-17-2013 01:45 PM Willys - Fuel Pressure Regulator
Finishing up on the fuel system, the supply and return lines turn up along the firewall. More separator/standoffs are used, one on the toe-board and one on the firewall. Both lines terminate at the pressure regulator mounted on the firewall. The fuel supply line enters the side of the regulator, and the fuel bypass back to the tank exits the bottom. The fuel line from the regulator to the fuel rail is still the same Teflon lined hose, but with a Kevlar braid instead of the stainless.

The fuel lines are run along the inside frame rail using aluminum hose separators. The separators and hoses are kept off of the rails by rectangular aluminum tubing stand-offs with a through bolt to the frame. This keeps the hoses in line with the filter and allows routing past the rear brake proportioning valve and makes for a cleaner looking installation. The separators are also spaced close together to give the hoses plenty of support.

The fuel supply and return lines will be routed the same as the oil lines by following the curvature of the frame forward through the frame cross member. Hose separators bolted to support bracing between the frame rails will secure the hoses and keep them away from all of the moving suspension parts. The lower hose is the supply from the in-tank fuel pump to the fuel filter; the upper hose is the fuel return from the pressure regulator.

Holes were drilled through the floor and the bulkhead fittings were installed. The rear interior bulkhead will be installed in front of the fuel hoses, and just behind the roll bar braces. Third photo shows the finished in-vehicle hose routing. The bulkhead fittings will allow the hoses to make a 90 degree turn directly under the floor and also eliminate the need for grommets.

Since the body has been off of the frame in order to make plumbing work easier, the fuel tank was mocked-up on the frame so that the fuel lines could be routed. The plan was to have two short -8AN supply/return fuel lines go from the tank to bulkhead fittings in the floor. Separate hoses will then go forward to the filter and pressure regulator on the firewall. The bulkhead fittings were located on a wood strip simulating the body floor in order to measure the hose lengths needed. All of the fuel line used is Teflon lined. The third photo shows how the hoses go from the tank through the floor.
