You will need to install a pressure gauge between the supply pipe from the tank and the filter inlet pipe.Pressure should be between 2-3 Bar .In real money from around 30-45 psi.hth

Thanks for that,I was wondering if anyone knew a quick check eg fuel from filter housing just flows or hoses out.Will the HP pump need a minimum inlet pressure to work,?
