venting question

My first post here, so i will do my best to explain myself since i have no pictures to post. I have a bathroom that was roughed in downstairs when the house was built about 10 years ago. I am moving where they placed the tub rough-in because it wont work where it is. My drain work starts with a sink rough-in drain on one wall where it is vented with a 1 and 1/2" vent. Then then about 9 feet down the wall is where the new tub will be placed. My question is will the one vent be sufficient for the tub as well or will i need to vent the tub sepparately? It would be a huge problem to vent the tub if i did'nt have to. All of this runs to a sewage ejection pit in the basement which is then pumped out to the septic system. Thanks for any help you can give

I believe 9 feet is too far for wet venting.

In my code book, wet vent length is not restricted, trap arms are. The drain pipe acting as the wet vent portion should be 2", though. The dry portion above the sink tee can be 1 1/2".
