In another thread, John Pol asked for some tips on building an electric fuel pump similar to the style used in 60's and 70's drag cars. The first thing that came to mind was Stewart Warner. I've built a few electric pumps, but they were generic cylinders with fuel line fittings on each end. Here's an example on the chassis of a Revell 32 Sedan (in front of rear axle). I'm sure this in not what he had in mind, so I decided to try building one a little more like the old SW pumps. The pump consists of a main body, with some slightly larger diameter bands, and a sediment bowl on the bottom. Essentially, this breaks down to various diameter cylinders. Rather than glue a bunch of cylindrical slices together, I went a different route. 1/8" tube was used for the main body. To duplicate the protruding bands, I wrapped some styrene strap around the 1/8' body. The strap in this case is .015" X .040". For starters, the strap was laid perpendicular across the body. A small amount of liquid cement holds it in place. After a short waiting period, the glue was set enough to finish wrapping the straps around the 1/8" rod. More drying time, and then the excess strap was cut off with enough left to completely circle the body. Now it's time for yet another application of glue. This represents the main body casting for the pump. Now for the sediment bowl. I found a scrap of 3/32" rod which is slightly smaller in diameter than the body. Another scrap, in this case 1/16" hex styrene rod, was glued onto the 3/32" rod to serve as a mounting pin. It will slip into the end of the pump body. Why make it separate? This piece and the body will be different colors. To get the best color separation line, the pieces can be painted separately and then assembled. Here's the sediment bowl.
