Been making up an air pump to pressurize a fuel tank and was wondering if Ulsters fitted with such a fuel system incorporate a pressure relief valve or does the driver just rely on watching the pressure gauge while pumping, my engineering instincts say I should fit a blow off.
This prompts the second question - what pressure to set it at, something low, 2 or 3 Lbs/Sq inch?
