Vulcan sells donaldson filters that are used on Cat equipment... especially being 3 micron, it's not something you want on the suck-side of your raptor. I'd move it forward and get rid of the stock can or ditch the vulcan, I personally see no need for 2 fuel filters.

 

I'd keep it unless its a problem. I currently have 3 filters, and prefer that over less. More filtration is better then not enough.

 

Yea Ra that's what I've been told is it's better to over filter then under filter so just gonna keep the vulcan 3 micron on it and put a draw straw on with all half inch lines and see if that frees it up anymore
