Reply To: Pressure rating for OMC 1950’s tanks

[George Emmanuel]

Crosbyman,

As stated at the beginning, my goal is to put to rest rumors that pressure tanks can explode in an article I’m writing. The OMC tanks all  have a built in pressure relief valve that vents at 7-9 psi per conversation with 2 retired OMC techs. But to more fully explain the safeness, I need to determine the maximum rated pressure for the tank, so I can show the margin of safety. So, for example, if the tank were rated at 36psi, there would be a 4 to 1 margin. I’m confident there is a rated pressure, but I’ve got to find the person who knows, and now that OMC has been long gone, I may not.

I’ve been trying to track down a friend of mine who was V. P. of OMC’s Performance Group which manufactured the racing engines and were doing the testing of the prototype V-8’s in hopes he might know. I’ll keep my fingers crossed!
