Hi Colin, I have a '78 Spider (which I've owned for 26 years) and mine most definitely has an in-tank pump. I have also seen contradictory information from vendor application guides. I converted to Webers years ago and that little in-tank pump is all I need to keep the carbs happy. As rust in the tank worsened a few years ago I had to frequently pull the pump and free the brushes. A few times the car would die, I wouldn't hear the pump groaning so a few taps on the fuel tank sender flange is all it took to get it going again. When I got home I pulled the pump to clean out very small particles that would inhibit the spring loaded brushes from making contact with the commutator. I cut the crimp at the top of the pump and added 3 screw around the outside of the can so I could easily take it apart and clean it when needed. I finally gave in and bought a new fuel tank - problem-free ever since.
It is not a big job to pull back your trunk carpet and look to see if the fuel tank sender (flange with 6 small screws) has 3 or 4 wires going to it: 1 - Black ground 2 - small gauge wires for the sender 1 - red larger gauge wire for the pump (if you have one) So just for fun I looked at the 1978 electrical diagram and it doesn't show an in-tank pump for a '78. Hmmm.

Is there a secondary pump in the tank or not? I keep getting contradictory information.
