Defender seems to carry fuel fittings for everyone. You do need to use a pair from the same OEM, unfortunately there is no standard for conformity. They have fittings from most OEMs as well as those produced by third parties like Attwood and Tempo. Defender generally does a good job of indicating which fittings goes on the tank and which attaches to the engine, as opposed to simply stating the gender. There are aftermarket fittings which thread in to an engine and fitings with hose barbs. There are also fittings with hose barbs which will thread into an engine. Of course the hose barbs need a hose clamp to secure the hose. Gas rated hose and clamps should be available at your local hardware, big box discount store or DIY center. If you study the offerings for a while you should be able to hook up any tank, even an inexpensive aftermarket tank, to any engine. steve Steve R.

The Honda fitting wont work and an OMC fitting either. Al my sources just shrug their shoulders and say ..."those things for a Nissan a hard to find". Any suggestions?
