i'll get a new filter as it was on my list to be replaced next anyway then i know it will not be blocked and if she starts i know i can leave her instead of disturbing the fuel system again to put the filter back in place. is there any particular way of ensuring i have no blockages in any of the pipework. my mate spoke to his neighbour who used to deal with plant diesels and he said about using an airline to blow down the fuel line to the tank and if we can hear bubbling in the tank then the line is unblocked but again i have the problem of the banjo connections to do this.
