I recently changed my fuel pump and installed a Bosch (OE supplier) complete hanger assembly, pump, strainer, fuel sender.
Now my gas gauge will 'float' about a 1/4 - 1/2 tank or more when I drive. It will drift down towards empty, hang out there a little bit, and drift back. It does it slowly (say over the course of 10-15 minutes or so). The needle doesn't rapidly move back and forth. It will move from say 1/2 tank to 1/4 tank in 10 seconds or so and then hang out at 1/4 tank for 6-10 minutes and then take 10 seconds or so to come back to 1/2 tank. That's representative of the behavior I am seeing.
I tested the Bosch unit before I installed it and the sender read perfectly. It's awfully coincidental that a week after installing the new sender, the gauge started acting flaky but I don't believe it's the sender.
I started reading about the anti slosh module (didn't know they even had one) and my gut tells me that's the problem. Anyone know if they're available anywhere anymore or do you have to get one from a junkyard?
I plan on filling up with gas (so I know the level) and monitoring miles driven, checking the ohms reading at the pump connector and comparing that to the gas gauge.
Any other troubleshooting tips? Does it sound like the anti-slosh module?
