So, the gas tank on my 2003 FWD Base Vibe with 190K miles is leaking gas (for the third time). The first two leaks were a small hose fitting comes of the back of the tank - first, it rusted the whole way around the fitting, and I patched it with the 2-part gas tolerant epoxy. Then, it started rusting and leaking around that patch, and I extended the patch size. Now, it seems to be leaking somewhere off the top of the tank (but not visible from the access hole under the back seat. To retain my title as the cheapest person on earth, I'd like to change the tank myself. There are new metal Ebay tanks for $180, and pull it yourself tanks at a junkyard near me for $50. This leads to a bunch of questions:

1) How hard is changing the tank - rusty bolts? humanly impossible plastic hose clips which refuse to release the hose from the tank/fuel pump/evap canister?

2) Would you even consider a junkyard metal tank from the same rustbelt towns in western Pennsylvania?

3) Can you swap in a 2005-2008 plastic tank? Is it the same fuel pump with the same gaskets as the metal tanks? If I pulled a plastic tank AND its fuel pump does is save me a little work or lotta work?

4) Should I just take it to local mechanic (not dealer) and eat the $750 he wants to change the tank?

I have 190K miles on original fuel pump and no signs of trouble, and unlike some of my other cars, I don't have to drop the tank if/when the fuel pump finally dies - just pull the back seat, so I'm not feeling the need to swap fuel pump just because I'm dropping the tank.

Any input appreciated. State inspection is by the end of September, and the leak/smell is bad enough that the station is likely gonna fail me (plus that little check engine light.

Thanks,

My 2004 has a factory plastic tank. I'd go that way, for sure. Try it yourself, if you are capable.

Did you replace your tank? My son's 03 gas tank started leaking as well. I wasn't sure if i should go with the 04 plastic tank or the steel tank? Where did you get yours? Any issues?

Sorry for the slow feedback - I did go with the steel tank from RockAuto. It wasn't too bad of a job - it's posted ever here:

Hi I just acquired an 07 vibe plastic tank for my 03 Vibe. Any and all advice is most welcome

As far as I can tell, the bottom line aside from the physical differences like the hole location is I will need a matching cluster if i want he gas gauge to function properly?

I'm assuming the fuel pump from the 03 will not fit?

Thanks in advance

The only thread I can remember about putting in a newer plastic tank to replace an older metal tank is

Sorry I went with the RockAuto metal tank and it got me a bunch more years, plus my kid a bunch more years. Greatest car ever, but Pennsylvania rust finally got it where the State Inspection people said go away and don't ever come back. Good luck fitting the plastic tank to the earlier year Vibe.
