What is this? A 3 part question

[zbane]

(1) I've looked through the FSM and can't find this panel, nor whatever lays beneath.

(2) Is this the original fuel pump?

(3) I see another opening, is something missing? (if so, what)

I've got a constant whine, once the oil pressure starts to raise, coming from the back. I saw at AtlanticZ a tip about using felt as vibration insulation, so I tried it, thinking that was the problem-no help.

Hence the voyage under the tank and these discoveries.

1) first picture is an access to the fastener in the hole that the foam is stuck to-I believe the piece is a weight for dampening the rear suspension.

2) that is an aftermarket fuel pump-probably a generic walbro.

3) What is missing is the mounting and insulation(vibration) for the original pump.

The noise you hear is probably from junk in the fuel line being brought to the fuel pump. Drain the suction line and remove and clean(use carb cleaner) the sender(at the top of the tank(under the round plate in the middle of the rear deck-you do not need to drop the tank to do this).

In looking at your pictures-is the fuel pump supported by its hoses, or clamped around its body?

Many thanks! About how long, assuming basic mechanical skills and enough tools to get myself in trouble, should dropping the tank take? Rough guess is fine.

I was planning on cleaning the tank soon, your suggestion/thought about the noise will just move the cleaning up a few notches on the to do list...

The first time I did it, it took about an hour and a half-with most of that going to draining, cleaning, and getting off hoses with no damage. But the sender has a large filter element on it-unless the tank is chock full of junk, you probably don't need to pull it. When you take out the sending unit, you will be able to look into the tank and see what is necessary-again, you do not need to drop the tank to pull the sender!!!

Assuming fair weather, I'll give it a shot on Monday. I am going to have to replace all the hoses that connect to the tank, I do believe they are original, they are looking a little ratty. While I was under the car, a faint smell of gas was noticed, so I think it is about time to change them out.

Thanks for the suggestions and advice.

The pump is clamped down, I had just gotten it loose.

Upon removing the sending unit plate, this is what I found.

Would anyone consider this to be a very rusted tank? Regardless, the tank will be getting pulled and cleaned soon.

Judging from the cheap hose clamp on the filter, I would assume this car has had previous tank issues.

I would consider this to be in relatively good condition. At least compared to when I bought mine. Looking at your shot down into the tank, it looks to be relatively light on the rust. Go ahead and clean and seal, there is obviously some rust down there, but not worth replacing. After seeing my tank, I'll try to keep mine full when it sits from now on.

Your sender has been modified-there should have been a plastic caniser type filter about 2"x2" on the end-it clips into the two slots on the disk in your second picture-I have one somewhere, and will try to post a pic when the young one hits the hay. You would be ahead of the game to replace the original filter.

The tank could use draining and rinsing with a mix of gas/carbcleaner, but I wouldn't say it would be worth dropping it. Pour the cleaner mix through a filter, and run it back in the tank with several more gallons of gas. The sender will clean up well with a can of carb cleaner and a tooth brush/shop rag.

No dice finding the filter this evening-I will try again tomorrow morning-gotta look in the outer building.

I figured it had been messed with before. I had looked at my FSM and noticed the difference in filter design. I'll hit the parts stores tomorrow to see if I can "find" a replacement.

Here you go!

hell I can't get the picks to post...
