is this the correct oil sender for a 3800 into a swapped 1986 fiero ? the "stock 3800 sender" that was on the engine "Pegs" the fiero gauge. thanks

Use an 88 Fiero sending unit.

According to the info on the page you linked, that sender just turns on the OIL light, it will not run the fiero gage.
You need a sender with 0 - 90 Ω resistance slope.
