Fuel Gauge Reading Problems

Post by Tx_Cat on Thu Dec 27, 2012 1:19 am

So I am having that issue in my '07. I will fill up the car and needle will go to 3/4 (never full). This started happening last month. Read on other sti forums and sounds like a common thing but yet no def solution. It is really started to tick me off. Anybodyelse encounter the issue? How can I fix it..

Thanks and hope that everyone had a great Christmas

Typically speaking, issues like that are mechanical. Can be caused by either a bent floater of the sensor itself is is out of whack. Usually, the only way to fix that is to remove the floater assembly and check to make sure it isn't bent, or physically damaged or obstructed. Otherwise, you'll just have to replace that part.

May or may not be worth it to you.

Here is what you're looking for.

You'll need to remove the fuel pump assembly located under the rear passenger seat.


Once removed, this is what you will see


Here's the back. This is the area you need to be focusing on.


I honestly can't remember if this part is able to be ordered separately or not. On older cars of various makes, it is. However, on a few cars, it comes only with a complete new housing unit (which is stupid in my book). \I'd pick at Abel's (at Garcia Subaru of El Paso) brain as to whether or not that can be purchased separately.
If it can, as you can see in teh pic below, it's just a single plug and a couple of screws should you have to replace it.


If it's just a matter of an obstruction of some sort, you'll still want to remove it to clean it.

Hope this helps.

No problem. I just found the service manual, and the part is replaceable. The only other possibility you have is a bad gauge, which the manual states that you'd have to replace if it's not the sensor.
