Filler neck '36 ford dr for fuel tank     40 Coupe 08-10-2011 @ 6:30 AM reply profile send p.m. Senior Posts: 1674 Joined: Oct 2009 I do not believe the armstrong or the foot pound method will work properly to stop a leak in this area. I agree the spanner wrench is necessary, I believe Craftsman and MSD both sell one. I removed two seals from the neck of my 35. I replaced one, making sure both the tank side and the neck are clean and flat. Used neversieze on both the male and female threads and under the nut on the neck. Make sure the neck will tighten to the tank without a washer before installing one washer, other wise the nut may not be threading into the tank far enought.I had to pick a lot of crud out of the tank threads. flatfoot 08-07-2011 @ 8:55 PM reply profile send p.m. Member Posts: 260 Joined: Mar 2011 When I removed the tank to refurbish it the 3 lead washers was already in it so I thought it would be wise to put 3 back in. That's how and why I did that. I just hope I have it tight enough. Thanks to you all for your ideas and procedures. Very helpful.

We were lucky and it compressed the lead washer, and no leaks. If I were doing it again, I would LIBERALLY apply grease to the threads of both pieces. You don't want the friction of the threads to prevent the neck from drawing down onto the seat. The kind of grease is not crucial, we used common chassis lube.

I added them one at a time over a period of time until the leak stopped. When you buy these lead washers they come 3 to the pack. Some people get away with using only one. flatheadfan 08-06-2011 @ 11:35 AM reply profile send p.m. Member Posts: 450 Joined: Oct 2009 Dale- I don't understand why the necessity of three lead washers. I have never heard of any situation that more than one was needed. In fact, the factory only put in one. It would seem that multiple lead washers would only increase the likelihood of the neck leaking or at the very minimum cause installation problems. I guess I need some enlightenment on this.

I tightened it (by hand & arm) until the leakage stopped over a period of time. I never found it necessary to use excessive muscle to tighten it.

So did you use your foot or feet to tighten it or was using your hands enough? MG 08-05-2011 @ 2:24 PM reply profile send p.m. Senior Posts: 1254 Joined: Nov 2009 I found that on my '37, hand tightening the filler pipe was never sufficent enough to prevent leakage. Using a spanner wrench to tighten the pipe was the only way I was able stop leakage. flatfoot 08-05-2011 @ 1:43 PM reply profile send p.m. Member Posts: 260 Joined: Mar 2011 I am trying to tighten the filler neck on my '36 ford fordor. I removed 3 lead washers out of it when I had the tank redone. So, I put the 3 washers back(new ones) in. I have been able to tighten with two hands laying on back and one push tighten with my foot. Is this tight enough or do I keep going 'til it won't tighten anymore. I am notorious for breaking things trying to tighten too much. All ideas will be appreciated. Thanks. Dale Smith
