Oops. The fusebox under the hood is for the LT1. I don't know about the TBI fuses.
JimR, if the level sensor is good, I would like it. I just pulled one off a junkyard car, and the system still doesn't work. It's frustrating, because I traced the intermittant fault to a bad wire where the harness enters the sensor. But I don't know if the JY switch I put in is any good.
