Found the smell source
« on: May 01, 2019, 10:18:50 am »
Those of you who were at the March meeting may recall that I mentioned a gas small coming from my yellow car after driving it some. Here's the tank from that car. It appears to have been leaking at the fuel pump hole. I have a new O-ring on order from the Fiero Store.

Have you ever replaced it or did it just fail from age?

I think it failed from age. It  looks slightly flattened, which I'm sure it's not supposed to be.

May as well clean up the tank and seal it, while it's out.

Probably doesn't need much of anything, other than the new O-ring. We live south of the Manson-Nixon line.

There's a joke in there, Michael.  You've got to know Steve and his play on words.

The tank is mostly back in the car. One hose clamp is bad -- I kept turning and turning it, and it wouldn't tighten. I have more somewhere, but it was time to quit. I need to get that car back together soon, because the AC has decided to quit working on the silver car, and it's getting warm out there.

Nah. I might scrub it with a brush and some soap 'n' water, to remove the gas stains/residue.
I'm quite sure it's otherwise intact.

I finished putting the car back together, filled the tank, and drove it to work. No smell -- operation a success. I also replaced the filler hose set with a new set from the Fiero Store. I don't know who said the Fiero Store set was thinner, but it wasn't. And here's a tip. The set consists of the two hoses required stuck together. If  you take a sharp knife and separate them, you will find them MUCH easier to install. Even so, the small hose is a bear to get on, and I had to bevel the ends of the hose with an Exacto knife.
BTW, the old O-ring was just that -- a rubber O-ring. I don't think it was original. The new one from the Fiero Store had little tabs to make sure it was centered in the hole.

Well done TN, looks like a job worth doing that before it became a bigger problem. 

It might have been me mentioning a post on PFF about the Fiero store hoses being thinner.  Good to know they are not... Just need Sir Rodney or someone with affordable postage to offer them.

I was wondering whether to do the tank whilst cleaning underneath.  The straps look like they could do with a paint and, from your recent experience, can the straps be removed without tank removal? Looks they can be undone but not unhinged?

I've never taken the straps off, and I'm pretty sure it couldn't be done with the tank in place. And they are galvanized -- paint doesn't stick well to galvanized steel. I don't have any experience with a Fiero driven where road salt is used. Every one I have seen had clean straps that didn't need painting.

I don't know if the straps can be removed if you only intend to remove them and leave the tank in place, but I know they will come out about the time you get the tank back in place after replacing a pump or sending unit.   :(

They are only T bolts on the end of the strap that when the strap is pushed upward, will access a slot in the mounting bracket that allows for removal.

I think if you take the straps off the tank will fall down and go boom.  The only thing that would be holding it up would be the gas neck hoses and the gas lines.
