There Is A Difference

Second picture of the same problem if the coupling was not used.I have the tank loose and slid out but had to use the coupling to get the seditment bowl assembly to clear the support.

These couplings were on these tractors when I bought them.

Another problem: the fuel line from the bowl to the carb. isn't hard on our B. Instead, it's a regular rubber hose that's in bad shape. I was just going to replace it with another rubber one, but with my having to use this new, wider, bowl at a different angle (the one I took off was running perdindicular with the tank, with the petcock in the back), should I go with a hard line because of the 90 degree turn? What do I seal the threads with to prevent a leak on the tank/bowl? Thanks again!

According to the B/C parts book, there were three different tank supports used on the B. The latest one being for tractor ser B-58401 and up. That fuel bowl extension was apparently a standard part (219139) for all Bs ser B-51293 and up. There is also a reference that particular extension replaced an earlier one (912720) that was also used. My '42B (B-58812) has the original extension and there appears to be a little more room between the fuel bowl assembly and the tank support:

Thanks Rod, I didn"t know that. I did know that there was two different ones because I have one all painted up and started to use it and the tank was to low. The low ones didn"t have a hole for the wiring harness so I drilled one and then couldn"t use it.
