Ok, I fitted the Separator / filter to the rib this afternoon.
I decided to use banjo type fittings as this makes a tidy installation IMO. I sized the engine fuel line length just longer than required when on full steering lock and engine tilted etc..
I have manufactured an aluminium “tube fitting” that both the banjo’s will screw into just in case there is a problem, this means I can bypass the CAV if necessary.
After reading recent threads on the subject I decide to relocate the primer bulb adjacent to the fuel tanks which are located in the main console, it seems to work much better than when it was at the transom.
