I'm trying to replace my fuel pump, but the lock ring is rusted through and through. I'm trying the hammer and screwdriver trick, but I seem to be chipping off the tabs without making any progress. I hit it with some WD-40 yesterday, but that doesn't seem to have worked. Any ideas?

I do have a new one to use after getting this one off, so if there's a way to break the lock ring without damaging the tank, I'm open to that idea as well.

That is a mess and no reason why it would be like that. Water had to have gotten in and sat for a long tome. A dremmel and cut thru the ring just enough to break it open or a cold chisel . With a chisel you would need ot be careful not to damage the threads.

Alright, I've finally got it off with a hammer and a nail punch. It's strange that it is so rusty, because the underbelly is relatively fine for a car with 190k on it. I'll be sure to tread carefully.

Congrats on getting it off. I was going to suggest spraying it real good with Deep Creep and tap with a chisel occasionally and let it sit overnight if need be. That's what I had to do with mine and it didn't look nearly as bad as yours. Good luck with the rest of the job.

Maybe someone spilled liquid and it made its way under the seat. Does the driver side look the same?
I'd believe it. I'll have to check the other side tomorrow. Last owner had kids, and man was the underneath of the seat messy. Found some legos back there haha.

Toss the wd40 ang get some real penetrating oil.
Fair enough ¯\(ツ)

That part of the tank is:
A: On top of the tank.
B: Is outside and not inside the body

If there was a leak there, it would drip down and be under the car.
The access panel has foam for a reason. Seals off from the outside to inside of the car.

Sure there is- rust belt.

It only takes a few winters for salt to get everywhere, and then, even though
the car might be in California now, every time it gets damp it rusts some more.
Brackets like this are where it shows up.
And a well- shaped cavity like the top of the fuel tank's NEVER going to rinse
clean, even if you get the 'undercarcare' car wash.

Also, Hawaii, or on any coast- the water spray does pretty much the same thing.
But it has a different, top- down pattern, whereas the slush is thrown upwards
from the road.

Here's me, driving a rental Kia up to Ra-cha-cha
on a sunny morning in February. The white stuff on the
road is salt dust. It's like a dust storm when you pass a truck.
You can taste it in the air. It gets everywhere.

(It had warmed up for a day or 2, and the sun dried the lanes of 390)

Now imagine that as a semi- solid slush, being thrown up by your wheels,
the truck you're trying to pass, and everyone else around you.

That'll totally eat your gas tank's pump locking ring...
