hi guys I have two problems that may be related

the first problem is that the fuel gauge is saying that the car is always full even with the fuel sender not connected we have tested sender and appears to be working.

the second problem is that the blinker lights one the dash are staying on all the time when I put the left hand indicator on the right hand light flashes on the dash but tis working right on the out side

thought I had the bulbs in the wrong side but there is not enough wire length to change them
thanks josh any info will be helpful
