Gulf Coast Fuel Filter Warning
The filter itself (the factory version and not papertowels since they are difficult to find in correct size without colour all over Europe) was clean indicating it has not been doing it´s job and from Randal I learned that these factory filters have to have one gasket on each end or the fuel will by pass the filter having no effect. Reading the instructions from the company for factory made filter devices there´s nothing about these gaskets.
If you buy the expensive factory filters (actually made for oil filtering) and follow the manual for installing the fuel polish filter the whole setup will not clean your fuel !!
I have now setup the filter device according to Randals instructions with gaskets on both ends, something he found out after contacting the company having earlier fuel polish problems as well.
Being such a confusing and complicated setup I will change over to Racors fuel polish system while wintering in Spain
