Default Need Advice Please

I posted in general discussion..maybe I'll get advice here. I just bought a 1998 C5 w 32K miles. West Coast Corvettes said they did a complete inspection. First fill up, gas gauge needle dropped to just above half full and stayed there. Filled up again, same thing and stayed there after 120 miles of freeway driving. Called Chevy dealer..they said fuel sender in gas tank must be bad. Quoted $500 to $900 to fix! How can this happen in such a low mileage vette? What if I put in a can of fuel additive/cleaner..could that help? Could it be fuel pressue gauge,fuel feed pipe, or check valve? Should I ask Chevy to check all that first?

I'm running 245/45/17 tires...came that way..psi read 22, so I pumped up to 32. Got warning display overinflated to 47 psi! Never had low profile tires before...pulled off frwy and let out air...counted to 40 and tire pressure read 31-37 psi...how do you properly check tire pressures?

Thanks

Like the guys said over in the G.D. section, get a 22 oz. bottle of Techron ($7.00) its a hell of a lot cheaper than removing the fuel sending unit. The false readings on the tires, could be bad sensors.

245 45 17 is the stock size for front 275 40 18 should be on the rear. You need to purchase a good tire pressure gauge and set tire pressure to 30lb.If sensors read something else they are probably bad.
Try running some Chevron gas + add some Techron fuel additive. This will sometimes solve the gauge problems. If this fails to solve your problems contact WCC they should make it right.

I'll guess that you pumped up your tyres in a service station and used the reading from the air pump. In case you didn't know, those things are totally unreliable. As to the question of how do you properly check the pressure; um, with a tyre pressure gauge.

Default sync-sensors?

I had a tire pressure reading that drove me nuts. That was before I realized that the sensors were reading from the wrong wheels. The rear tires are reversed. Right is left and left is right. At some time ,maybe during a tire change the rims got switched and were never re-syncd . Since then I've been able to keep the tire pressure right and stop the DIC from driving me nuts!
