    I bought the V-band clamp from DMCH which has a part number that does not seem to be a standard part. I did some research on stock clamps and there are a lot of variables you can choose from.

    I was ready to try the Breeze VT10469 but decided that DMCH must have done a lot of testing for the proper clamp. But after finding out your not going to get a clamp that will compress the pump down since the ridge on the tank is so little I think it's not that critical. So if your a gambling man, try that VT10469

    The pump plate and tank opening are 4.5" dia. But like I said I don't think the band size is that critical.

    What are your plans for wiring in the gauge? I know the DMCH pumps come with their own logic box or whatever and I'm not sure if this is just to prevent sudden swings on the gauge due to inclines or what. With all the threads about these newer style pumps, I wouldn't mind transitioning over eventually, especially since I don't need to worry about high pressure pumps for K-jet.

    Fiberglass closing plate

    I got my new Dremal and finished the cutting for clearance onto the closing plate. Then I put some thin foam over the pump and a layer of Saran wrap. Bolted the plate down and wet 3 layers of 6 oz. glass. To wet the glass you lay Saran wrap on your table, lay the first layer, pour some epoxy on the glass and spread it over the glass. Then lay the next layer over the first, epoxy, next layer. Then you can lift that built up glass and lay it over where you want it. Leave the Saran warp on it an you can just use your fingers to press the build into place. Keep pressing every hour or so until your epoxy hardens. My T88 epoxy takes 24 hours to get real hard but starts setting 2 to 3 hours after the mix. The Saran warp will pull off after the epoxy sets.
