I need a boost guage for the Escos.

It needs to match the diameter of the Stack ST700 guage, ie 80mm Black face & rim - white numbers & red needle.

Would be ideal if the needle sat in the same position as the stack clock when idle.

Guess it needs to be a min of 30 psi & a manual (ie pipe on back type)


an pics or links would be appreciated
thx
