Yes, the market is loaded with the Chicom knock off Ford valve. It is an exact copy. Uses the same electrical Ford Plug.
Plastic Fuel lines connect the exact same way.
E-bay sells them as well as Amazon and a whole slew of of Auto par sites. Price range is $50 on up.
The original Ford Valve with the Ford name has pollack on it also. Pollack makes their own version, but the electrical plug has round pins compared to what Ford used with the flat pins.
I installed one of the chicom valves, worked good at first, then would not switch tanks. Just ran it off the rear 38 gal tank for a long time, then a month back I got to fiddling with it, and the gauge showed the front tank, but would not switch back or either way.
So what ended up going on, is I was pulling fuel from the rear tank, and returning to the front tank.....and you know what eventually happens.....I now mark my territory where ever I go. It over flows.
When I originally installed the 38 gal rear tank and the new FSV, the original Ford plug had one of the clips broken off. I found one at PNP in better shape.
Cut the PNP plug with plenty of wire, and the old one, cut the wires at the plug, this way I had plenty of wire to deal with.
The 2 wires from the rear and front tank are wired to a Weather pack plug, and the 3 going for ward are in a separate weather pack plug.
I did it this way, if i ever install the pollack one with round pins, I can make another separate plug.
One thing I found out, the early FSV like on my 86 is a smaller plug, and the later trucks uses a larger 5 pin plug.
I pulled 2 FSV from PNP, one off a gasser F250 and one off a 90 or 91 F250 7.3. And took the plug along with 3ft of wire harness each way from the valve.
I took apart the chicom one along with my original 86 one, then noticed the recess the plugs live in are 2 different sizes, along with the plugs.
The picture of the white plug in post# 2, is the older style smaller plug. Use it in the later newer FSV`s and it will not fit tight.
Look at post#7 in this thread, this is what the later plug looks like.
