Frank Y Posted August 19, 2022 Share Posted August 19, 2022 I'm looking to put the 2nd tank back on the passenger side of my B. The tank that is on the driver side would belong on the passenger side, but I'd like to match the tank I have to a larger tank for the driver side. Can anyone tell me what series Mack used a 2MB 4814R P2 tank. Thanks everyone!

Freightrain Posted August 21, 2022 Share Posted August 21, 2022 The passenger side was 40 gal, the drivers was 50 gal. since there was no stack bracket in the way. This was square tanks, not sure about round tanks. Quote Larry 1959 B61 Liv'n Large......................

I would like to find out what model trucks used this tank so I know what model I need to get the larger tank from.

Freightrain Posted August 22, 2022 Share Posted August 22, 2022 1985 build date, so likely just a replacement B model tank. I'm not familiar with any other model that used that style of tank. Sorry. Hope someone else has some input. 1 Quote Larry 1959 B61 Liv'n Large......................

B tanks are about maybe 2 inches shorter height wise. It looks very similar to an older R or DM tank but the larger DS tanks on the DM had the double step.
