1956 Jeep CJ-5: Project Ground-Up Part 4

Posted in Project Vehicles on July 1, 2012

Most magazines do their project build-ups at custom off-road shops with a lift, brand new high-zoot parts, and a herd of fabricators rushing this way and that. Well we here at Jp magazine realize that that’s not a luxury that all can afford. And we want you to know that you can still build a Jeep in your garage by yourself. We have been building project Ground-Up with our own two hands (and a little help from our friends) in our garage while dealing with everyday life and while tinkering with other Jeep projects. The end result is that we occasionally toss parts at this thing that don’t seem to make too much sense when in print. That’s the way it goes in real life—you bolt on what you can when you have it.

Last time in project Ground-Up land we tossed in a set of retro seats, a simple, yet effective rollcage, 33-inch BFG tires, stamped-steel wheels with some hot baby-moon centercaps, and modded and installed our XJ’s hacked-up wiring harness. This time, the crazy build continues as we get a bit closer to turning the key. First we attack the fuel system with a vengeance by modding a brand-new YJ tank we found on Craigslist, building a fuel tank skidplate, and adding a fuel pump, filters, and pressure regulator. Finally we plumb the system with a coil of 5⁄16-inch steel line and fittings from Quadratec. We then get a touch further with the wiring by adding an Optima Red Top battery and CJ battery bracket, also from Quadratec. Next we toss together a totally tubular transmission crossmember duderino. Finally we plumb the brakes with some 3⁄16-inch steel line and fittings, again from Quadratec. Follow along as the build of our vintage yet modern ’56 CJ-5 continues.

Yea, so this fuel tank skidplate is sturdy enough to deflect small arms fire (we are thinking .22-caliber from a few hundred yards) and it ain’t light. That’s perfect for this project since the early YJ tank we are using hangs down a little lower than ideal. It sits low in order to fit between the framerails and tuck behind the rear axle. We made it out of 3⁄16-inch plate steel strategically strengthened with some 3⁄16-inch strap pieces. It mounts to the rear crossmember and to the framerails just behind the axle. The rear crossmember pinches the rear of the tank and the front is secured with a couple of bolts and some tabs that we welded on the new tank. Weld on an old tank and you will create a huge hand grenade. Don’t do it.

We finally decided on using a stock 4.2L(’87-’90) YJ sending unit, a Fram G3850 filter, a PN E2000 fuel pump, and a Corvette filter/fuel pressure regulator (PN Wix 3737/ NAPA PN 3737). We were told about the Vette part by a Jeep shop-owner-buddy who swears it’s the cheapest way (under $50) to regulate the pressure of the E2000 down to a level perfect for a 4.0L HO or 2.5L MPI engines. Plus it has a return line (orange arrows). You will also need Dorman PN 800-155 for the 3⁄8-inch fitting exiting the regulator, a double flare tube, some 3⁄8-inch fittings, and adapters to get the Dorman part fitted to the 5⁄16-inch metal fuel line.
