sorry for the commenting on the old thread, but does this mean that I really don’t need the in tank pump if this is installed on the right side where the original spica electric pump was?" For best results, mount the pump close to the fuel tank and below the fuel level. The pump is self-priming to 24 inches vertical fuel lift. Vertical mounting is preferred to assure maintenance of rated pressures."
With my old-style gas tank which has the fuel line outlet at the bottom of the tank priming the pump is not an issue. It is pretty much a level shot from the tank outlet to pump input. No worries about 'vertical lift' for priming. Frankly, I would think that even using a later style tank which pulls out the top of the tank should be OK as the drop from top of the tank to pump intake would (eyeballing things) be less than the 24 inch max self-prime height.
