Hello, recently my gas tank in my 97 civic coupe rusted out. I purchased a gas tank from a 2000 civic sedan. I thought everything would be the same.

I only have a nipple that comes off the tank and to the exhaust pressure bypass and pressure sensor. On the 2000 civic tank there is an actual tube that goes into the tank and 4 hoses that come off that. My question is can i block some of those off or what do these hoses go too.

Any suggestions would be appreciated.
