Any inward opening injector will have little return fuel when working right. Rotary pumps have more return to help cool and lube the pump internal cam ring and rollers. There's one more thing that should be checked. If NAPA/WIX filters are used MAKE SURE the filter top outer groove DOES NOT have an O ring in it. That's the filter inlet, I've seen several times where filters have been changed and an extra O ring has been put in that groove by mistake, either shutting off completely or severely restricting fuel flow. Top of filter is sealed by the base groove O ring. Had a Ford TW 35 on the dyno just this spring, owner drove it five miles. Pulled OK on the dyno about ten seconds, then lost power, and died.

We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
