2000 Elantra fuel pump issues

**Hi everyone.

A co-worker of mine has a 2000 Elantra that's on its 3rd fuel pump.
It's died twice in the driveway and once in the middle of NoWhere,
Ohio. The dealership told her that it's possible the gas tank cover is
corroding and somehow causing a problem with the fuel pump. I don't
know if they mean that corroded bits are getting sucked into the pump
or what. Apparently, the pump was getting current but just not moving
the gas.

Does this sound plausible? She didn't have to pay but her peace of
mind is shot. Is there a TSB out on fuel pumps and/or is this a known
problem?

Thanks

There's no TSB about this, but I've seen vehicles where some part of the
fuel tank or filler neck was rusting, causing fuel pump failure. I got
nailed on this a couple times myself. Replace the fuel pump. Failure
again a couple weeks later. Eventually, I figured out that the
characteristic fuel pump whine was definitely a higher pitch if there was
a rusting issue. The dealer's assessment is plausible.

 

**Thanks, hyundaitech. Is there anything that she or the dealership
can do to prevent this from happening again?

Thoroughly clean or replace the tank and replace whatever components are
rusting. This won't be cheap.

 

**Thanks for your help!

My sister's 99 Elantra has a similar problem. The only thing I did was clear out
the contacts to the fuel pump and that took car of the problem.
