If it goes bad it will cause the problem your describing. I had the same problem on a Plymouth Horizon. The check valve is mounted on the passengers side of the motor toward the front, under neath the exhaust and intake manifold.

Remember that the gauge and the solenoid are on separate circuits that are connected to the same switch. That is. When you switch tanks the gauge circuit and the solenoid circuit are switched but one or the other could be inoperable. In my case the gauge worked but the solenoid wasn't activating. I bought a solenoid / valve from Ford and it was easy to install and as I recall quite cheap. BTW remember to drain the fuel tanks or crimp the lines to the valve before changing it. The gas comes out of those lines in a hurry. I'll let you guess why I know that.

I understand the leaf arrangement you talk about. This is not what I have now on my truck. I think there were originally 5 leaves in the stack on the stock setup. The new leaf was installed in the number 4 position (no. 1 being closest to the axle, 5 furthest from the axle).

I fixed the same sort of problem on my '83 by getting some 3" spread square U-bolts with plate from the hardware store.

Yeop. done it on my '83 F150. Its a pretty straightforward job ... the release rod connectors unfasten at the handle, then just unbolt the brackets at the outside edge of the tailgate, and slide the whole assembly out. The handle itself attaches with 3 bolts which are found on the exterior surface of the bed-facing side of the tailgate. Go to the auto parts store and buy some extra clips (you will find the originals installed on the ends of the release rods where they attach to the handle), because invariably, one will break. The bolts that hold the tailgate handle/latch hardware in my '83 are metric ... either 8mm or 10mm, or maybe some of both (its been a while since I fixed it) ... I suspect that yours is metric too. == FTE: Uns*bscribe and posting info http://www.ford-trucks.com/faq.html ------------------------------ Date: Wed, 13 Oct 1999 16:47:15 -0400 From: Dave Heverin Subject: RE: FTE 80-96 - Re: REAR LEAF SPRINGS Thanks for the suggestion.

You will find two lines from each tank and then from the switch forward there are two more lines, one feeding a high pressure pump and the other a return. The lines between the tanks and the switch are also supply and return lines for each tank. The way the switch works is, when the pump in the tank is switch on the pressure from it switches the pneumatic switch over to that particular tank. You likely have one of two problem. 1.) The front tank pump is bad. I had this happen recently and I replaced the pump along with the sender with aftermarket parts. This led me to have problem 2.) The rear tank has had its pump replaced with an aftermarket pump. The pump I replaced mine with, when switched away from, did not allow pressure to bleed off. So, when I fixed my front tank, then the rear tank would no longer work. When I tried to switch from the front to the rear tank, even when full and even when I could hear the pump in the rear tank running, the truck would run out of gas. So, what did I do. The only thing I could. I replaced the other assembly with aftermarket parts and this is where my problems really began. Once I had both replaced, when I tried to switch tanks, neither would work because the switch was held in a middle position that wouldn't pass fuel from either tank because both inlets were pressurized. The only fixes were to crawl under the truck and bleed one of the inlet lines to the switch or to wait several hours until the pressure eventually bled off on its own. You wouldn't believe what I went through to find all of this out. The parts I used were made by Carter/Federal-Mogul. Do not use them. If you do try an aftermarket part, if you can find one, there is an easy check to make to see if it has this problem. On the OEM part you can blow air freely back through the outlet of the pump. Not so on the Federal-Mogul part. I have contacted them about the problem numerous times but they ignore me. So, for my part, don't buy Federal-Mogul parts.
