Hi I am new here. I have a 70s Ford 4500 3 cyl diseal hoe. This machine has run great since I had it. This winter after some extreme cold I found Ice in the fuel filter even though I had run fuel conditioner thru the machine. I brought the machine inside emptied the fuel tank, changed the filter, blew out the lines, drained the pump by the bleeders. I installed fresh fuel,new filter, bled lines, and pump. I can not get the pump to work. I have disconnected the lines going to the injectors at the pump, but I get no fuel coming out. Also can someone tell me how to check the position of the timing gears which drive the fuel pump. I have looked around and can not seem to find a CAV pumpfor this machine, or anyone in the Maine area that repairs them. Thanks one and all for any help.
