If you have the Meyer E47 E57 E60 and you have problems with it many places will push you to buy a New E58H or the E61H. These have been upgraded with a new angling block and valves but we still recommend sticking with the older pumps cause it is not that nice of a conversion on the Classic or Custom mount because they only make these pumps in the H version. The H is 2" taller if you bolt it in place of the pump you are removing you will hit the tank on the frame when in the up position to fix this you need a lift arm with a mounting hole further front to prevent this.  You also need the wiring harness adapter that takes it from the bullet connectors to the weather proof Deutsch connectors. You also need couplers that plug into the pump so you need to change the ones on your hoses and the ones they offer are a SAE thread instead of pipe so you also need the Adapter 22652 that change the thread for that.  Below is a picture of the kit we offer.  The kit # that gives you the harness 15912 and couplers 22443 and 22444 is kit  08128.  Below are also pictures of the E58H and the E61H. You can see the E58H looks just like a E57H but has a different block on it they moved the a/down valve out of the base and changed to better valved the E61H is the same pattern as an E60H with the new block.
