356 racor
Hi John,the pump is really useful when you need to reprime after changing the filter. that said, I'm not sure if anyone has a better solution. We have 2 of the racors in parallel with a 2-way valve so we can switch quickly if one becomes clogged. you can buy the clear bowl separately, around $20, so you can see water/crud. to change the filter, put an absorbant mat in the bottom of the compartment and a plastic bag around the filter-remove it and replace with a filter that you've mostly filled with diesel. use the pump and bleeder to get the filter primed.
