The Pace Car, which hasn't been running right since I got it last summer, is dieing when you get on it. Idles find and goes slow find. Had it in a garage and the guy rebuilt the carb, checked the pump, lines, filter and stuff. Also checked out all the elect stuff. He said only thing left is drop the tank and check that sock thing. I'm going to try that myself, so just wondering how easy it is and what to look out for. Car did sit for a long time before I got it so maybe things are gummed up. He did say the carb was a mess from old bad gas. I have a scissor lift so I can get under the back end pretty easy.
thanks for any ideas.

Not sure if you have to drop it?
Someone one will know for sure.

If you are referring to the strainer (sock thing) i replaced mine without removing the tank. I removed all the fuel from the tank, I got my 13 year old son to stick his small hand into the tank
he reached down to the strainer removed the old one and put the new one on. If the car was in storage for a long period of time, you should remove all the old fuel.

You should be able to remove the fuel sending unit and pick-up from the top of the tank. Make sure you have good connections when you put it back together.

If you "Chromie' guys can remove the sending unit without dropping the tank, then you're very lucky. Somewhere along the line GM made the fuel door opening too small to pull the sender through on the late models 
. Before you drop the tank, remove the rubber boot surrounding the filler hole and inspect the 2 short hoses to the right (if not already done), they are famous for sucking air if they've never been changed yet. You can tell by looking.

Have you had the advance, timing checked out? Bad gas will give you problems at all speeds, but low volume will show up on acceleration. One thing at a time, good luck with it.

The earlier cars, from '68-'75(or so) had the sending unit on the bottom of the tank. The later cars have it on the top of the tank. The '82 cars I think you can get the unit out without pulling the tank, but the other ones require tank removal...
If you have an air compressor, you can pull the fuel line off of the fuel pump, and blow back into the tank(take the gas cap off first!). If the sock is really stopped up, it will blow it off of the end of the sender. If it has some crap on it, it may blow enough of that off to see if the performance improves any. If it does, then I would pull the tank and replace the sock. If you hear a loud "pop" when blowing back thru the line, then the sock was stopped up, and blew off of the end of the sender. In that case, you would still need to remove the tank to install a new one, and prolly clean the tank while it's off.

Looks like some good advise. I'll be right on this Saturday morning. That is, right after my weekend coffee run in the SA if it ain't raining or snowing 
as they say it might do.
