Licensed to kill Posted September 21, 2021 Share Posted September 21, 2021 I'm going g with dual stacks on my B-61 but I see that the last fuel tank is bigger than the right, presumably the right is smaller to allow room for the stack. Had anyone added a left stack while still issuing the bigger 50 gallon tank and if so, got any pics??. I could use another right side 40 gallon tank the left but then would have to relocate the saddles but would rather not if I don;t have to. Suggestions?

Freightrain Posted September 22, 2021 Share Posted September 22, 2021 I've seen a few variations of putting a left stack on a B model. I went with using another 40 gal tank and just duplicate/mirror the right hand top and bottom brackets. I didn't have to move the fuel tank brackets, as the tank is just longer on the one end(the end that would cover the left stack area) and using the right tank will just slide right in with no fuss and clear the stack. 1 Quote Larry 1959 B61 Liv'n Large......................

Popular Post AZB755V8 Posted September 22, 2021 Popular Post Share Posted September 22, 2021 The tank saddle brackets do not need moved at lease with the Mack round tanks. The steps would be in the wrong place to use a round right tank on the left side. A shorter Left tank is needed. Mack produces short aluminum and steel B-Model tanks for both sides. Maybe a steel right side tank could be used, fuel cap would be reversed though. In this installation a reverse frame bracket was fab'ed up to match the right side. The tank is a 55 gallon left hand Mack tank that matches the right tank. Stacks are straight pipe 5". 5 Quote Link to comment https://www.bigmacktrucks.com/topic/68219-left-hand-stack/#findComment-480307 Share on other sites More sharing options...
Popular Post Freightrain Posted September 22, 2021 Popular Post Share Posted September 22, 2021 (edited) I assumed square tanks. Here is an old shot of the steel tanks.
