It is worth consideration. however, I think the idea of redundancy for the relay is unnecessary. Seriously, how often do relays go bad? I think just keeping a spare relay and hand tools on hand (standard fare for ANY fiero owner) is the way to go. For the time being, I just put in the used sensor which seems to be working fine.

But as these parts become less popular over time we are inevitably going to end up with cheaper auto parts manufacturers taking up the role of filling the demand for the dwindling market. The results are inevitable.

hopefully someone like the Fiero store or other, will pick up the gauntlet.



Good point. You really don't need two electrical paths to the fuel pump although I use relay redundancy but only to get more current to the pump for a modified 3800SC with greater fuel needs.
Replace sensor with one just having the gauge output. Then use the single circuit to drive the fuel pump through the one relay and just carry a spare relay. From the sound of things the new 88 sensors are imported crap and don't work right. The older style "can" sensors" fail if they get wet so the simple solution seems to be the one relay approach.
