Hi there good afternoon to you and sorry for the delayed response

My name is***** would be happy to assist you Today

Ok basically the system has ran dry and is now full of air

The only way to resolve this is To prime the fuel system when fitting new fuel filters the fuel system needs to be primed using a one way hand primer (primer bulb) or vacuum assisted primer with hoses attached in each side

One end connects to the outlet port of the fuel filter housing and the other end into a container/ bottle

The hand primer must be pumped until the filter is completely full of diesel then the pipe can be reconnected and the engine started

In most cases the engine will start and run but in some cases the engine will again cut out

In these cases we leave the hand primer connected between the fuel filter and fuel supply pipe to the pump and continue to pump it until engine starts and leave the primer connected inline and leave idling for a minute or two then quickly dissconnect the hand primer and connect the fuel pipes to the fuel filter

These engines will not start with continued cranking as there is no lift /electric pump in the fuel tank to deliver fuel to the high pressure fuel pump /engine
