I have a Mallory 140 pump.their web site says I must run a return at least 3/8 back to the tank.iused to have it dead headed and it worked ok as long as the engine was runnin.Anyhoo, now with it hooked up like their instr. when im going down the road and push on the gas my pressure goes down.if I keep accelerating it will go to zero.will it hurt anything just to keep dead headed.when it was deadheaded it was a little noisy but with the return its very quite
