My 78 spider has been subject to what I think is vapor lock on an occasional basis. Sometimes, when I drive from my house 4500 ft elevation to Bakersfield or LA, the low fuel pressure light comes on, always on the return trip. I understand that Alfa put an in tank auxillary pump on some cars because of this problem. I checked the tank, and I don't have one. If I install one, how will I wire it up? I have seen the pump on the centerline web site.
