if your fuel gauge is going crazy then your sending unit is messed up and needs to be replaced get new new unit and drop the tank and put it in

 

The slosh module doesn't interfere with the alternator's regulation. If you have a problem with the fuel gauge, it's recommended to do a resistors test to figure out if it's a problem with the sender or the slosh module. GL

 

no, i already put a new sending unit. its got to be the regulator.

the sending unit helped a little bit by calming the needle down a bit.

 

The anti-slosh module is located behind the instrument panel module, it's either a bolt-on type like:




......or a plug-in type (sorry don't have a pic). You should also check that your problem is not caused by a bad body-to-engine ground strap or connection. The fuel indicator will move when a load (head lights, stop lights, wiper motor, A/C...) is present, if the ground is poor. GL

 

anyone know if the slosh module is any different from the 8 and 4 cyl? theres an 88 4 cyl notch in a junk yard with the cluster that i want. would like to know if all the cars had the same fuel mesurement system

 

You can use the module from the 4 cyl., instrument panel and fuel sending units are the same. GL
