Alternator, Speed Switch, MFI Fuel Pump

Post by knapmann »

55amp S.E.V. Motorola Alternator - Fits 69-73 - I had this tested and inspected by an alternator workshop, it came back with new bearings and a clean bill of health. Unfortunately for me, my car should have a Bosch unit and this puts out the incorrect voltage when wired up with my Bosch external regulator. Should work perfectly when installed in a car originally fitted with a SEV Motorola unit, i.e. with a SEV Motorola regulator etc £120obo

Original MFI fuel pump with the 3x inlet/outlets etc - this was running fine on my car, not sure if it matched the fuel delivery/flow "specs" but the car ran without issue and it never leaked. I changed it out for a new one for peace of mind and kept this original as a spare, I now no longer need it, probably useful as an emergency spare for someone else. £150obo

MFI fuel cut off speed switch / rpm transducer - this is the guts of a brand new transducer ready to easily install in your original housing, essentially its just a small circuit board. I bought a new switch as mine was dead, took the circuit board out of the modern tacky housing and fitted it into my original housing for the look of originality, this is a very simple 2 minute job, it fits right in place. I used it for ~6 months before converting my ignition system to electronic ignition with magnetic pickup (a 123 distributor), I didn't know that these switches only work with points based ignition, so by doing the conversion I inadvertently disabled the fuel cut off and made this switch redundant. I have since found a different way around the issue and no longer need this switch as I'm not going back to points. -SOLD
