Chirco carries two different brands of the oil pressure switch that fits that dune buggy and sandrail. We carry the EMPI oil pressure switch and the Hella pressure switch. The Hella oil pressure switch is the top of the line switch. It is the highest quality that is out on the market. The EMPI oil pressure switch for the dune buggy and sandrail is still a great part, just at a lower price point. The standard Dune Buggy oil pressure switch fits all upright VW Air Cooled engines for both the vw sand rails and the vw dune buggys. If there are any questions, our VW technical support can take care of you.
