Hi: Can anyone tell me what the correct attachment hardware is for the fuel tank for a 1937 Model 78. My tank is 14 gallon with the thread-on filler neck. The tank flange has caged nuts attached to it. When I took the tank off, all three 3/8" attaching bolts had a coil spring with flat washers. One bolt had a drilled head. The bolt with the drilled head was 1-7/8" long which jives with the parts book (as far as length) but the other two bolts are 2" long which does not jive with the parts book...it says they should be 1-1/16" long...parts book also says only one bolt has the coil spring. The author of the The 37 Ford Book for the gas tank section also describes slightly different hardware than the parts book so I am a little confused as to what the correct hardware stack up should be. The service bulletin CD does not have any discussion about the tank attachment. Regards, BRL

I am pretty sure there was only one spring. There is the spring, same size as the one used to mount the radiator, two flat washers, a castle nut. The bolt has a hole in the threaded end for a cotter pin. This is used on one side of the gas tank. The other two bolts use lock washers and have a hole in the head of the bolt for the safety wire to be threaded through the bolt heads and then wrapped over the frame and the ends of the wire twisted together. They use the caged nuts that you mention. There are also rubber inpregated rectangle pieces that go between the top of the frame and the tank. This kit has been available from Ford Bolts, now available from Third Gen Automotive.

On the side of the tank which has one cage nut you use the long bolt with the spring and the washers. Safety wire goes through the head of the bolt and one end of the wire then passes through a raised bump on the inside frame rail and the two wire ends are twisted together. On the side with the two cage nuts you use the shorter bolts with washers and no springs. Safety wire passes through the heads of both bolts and then one end of the wire passes through the bump in the inner rail and the two ends are twisted together.

Hi Guys: Thanks for the info. Yes, my hardware has the anti-squeak pads on either side of the tank...which is correct. I also believe my tank is original and correct and all 3 nuts are cage nuts attached to the flange of the tank. Reviewing the parts book and 37 Ford book again after your comments, I think my hardware stack up should be: Passenger side attachment (single cage nut): 3/8" drilled head bolt, L=1-7/8"(p/n 350532-S2), coil spring, lock wired to frame Driver side attachment(2 cage nuts): 3/8" drilled head bolts, L=1-1/16"(p/n 350531-S2), lock wired to frame -I dont think there are any washers, nuts, or cotter pins specified in my configuration although I see there are for other configurations for 1937. All the bolts I have on my current installation are antique looking but the flat washers are stainless and look modern so I think they are incorrect. Thanks for the help and any more comments and discussion are welcome, BRL

As I recall there should be one flat washer under the head of the bolt that uses the spring and one flat washer under the head of each bolt on the opposite side of the tank. This message was edited by trjford8 on 4-28-22 @ 7:29 AM
