just purchased a fiero store fuel sending unit, it looks great. my question is this, i am using a fuel pump that does not match the plug on sending unit, my pump is marked on top, + and -, but which wire on the sending unit is positive and which is negative? one is grey, and one is black, the obvious would be that black is negative, but i just want to know if anyone else has done this? thanks!

i just did the same thing back n july , but i used an AC delco factory pump an i just pluged in , what kind of pump did you get? i know the fiero stores sending unit also came with adapters for non ac pump

it is Kemso high volume pump, my fiero store sending unit did not come with any other plugs, maybe they stopped supplying them, i just bought it. the new pump came with a plug. https://www.ebay.com/itm/Ne...p2057872.m2749.l2649

I doubled checked the plug conections before i hooked it up, it king straight forward just take your old sending unit an find the hot wire, look at ur old ac pump , it should have a
+ marked on it. aleast mine did so i was happy then . I hope yours is the same way. if all else call the fiero store an ask for a tech helper, ther really great at that

Low temp switch that turns the radiator fan on when engine gets hot
Did not have a wire going to it or the connector I would Purchase a new wire connector
That looks like it has about a 12 inch White wire lead but I have no idea where that would go
Or what color wire it would connect to
I have been using the A/C switch on the dash to force the fan on when needed
And this is getting to be a pain

You should probably start a NEW thread regarding Fan Switch problem
since this one is about the Fuel Gauge sending unit.
