You ever feel like you should have let that sleeping dog lie?
Fuel gauge wasn't working so I decided to do some exploratory surgery.
Pulled the tank this morning. Popped the pump out along with sending unit (they are one assembly on the 91). Peeked inside & saw what looked like river mud inside the tank. Dumped out the gas & couldn't believe the crap inside. Pulled out at least a pound of rust. Looked like some kid had been dropping random pieces of metal down the filler pipe. Un frickin believable! Sending unit almost rusted away, fuel pump metal rusted. Cleaned everything as best I could & put it back together until I can maybe find a good complete tank. Installed a new see through fuel filter under the hood Dumped about 4 gals of gas back in & cycled the pump. Heard it running & shut off. Tried that several times, plus just left the key on for awhile, nothing. Fuel never pumped up to the TB. Crawled back under to start pulling hoses & see if pump was pumping back there when I saw a steady stream of gas dripping off the tank. Looked closer & found I now have a hole in the tank about 1/8 in dia. Put a bucket underneath & drained it all. Going to hunt up some Marine-Tex tomorrow & try to fix it, then try & figure out why no gas is getting to the front. They say Marine-Tex is the bomb for repairs like this. Never had much luck with JB Weld or tank repair putty. Update at 11

Here's what I found inside. YUK!!!!

I'm going to agree with Snowfish, I have never seen one that bad, and I live in rust central!! :shake
Do yourself a huge favor, and replace all of it.
WOW, that's bad!! :O

Wow, that is bad. Put that tank in the recycle bin and start from scratch. It ain't worth the trouble nor time to bring it back to life. Ask Stiffcheeze if he can find you one and ship it to ya. Heck, I've got a Gen 2 tank with all the goodies that I'll probably never need, but the shipping would kill the deal.

Yeah, I'd like to get a new or very good used everything. Can't locate a new sending unit. Car ran great. Only reason I pulled it was because the fuel gauge wasn't working. Can't find any Metros in the boneyards around here anymore. Anybody got a good working sender they want to get off of? Big Rhino posted a link for a new tank @ Rockauto & I could buy a new pump, just need the sending unit.

rockauto for the new tank, bowens on ebay for a new fuel filler hose, ebay e8023 fuel pump and strainer, and mythstae for a clean used fuel tank door/ sending unit assembly.

the tank is way beyond patching.

on a side note, those see through fuel filters usually won't take the fuel pressure for an injection system. they are more for low pressure carbureted systems. i recommend a steel canister type filter.

Your fuel system will love the filter located at the tank. Traps that rust and crap and keeps it out of your fuel lines as well.

Good point. What was I thinking? Heat must have fried my brain today.

Lemme dig and see if I can find it.

FYI
That filter is only rated to 10 PSI according to the manufacturer. :oshit
In fact they say
Quote:
 
NOT FOR USE WITH FUEL INJECTED SYSTEMS
OR FUEL SYSTEMS EXCEEDING 10 PSI FUEL PRESSURE.

Link--->Installation Instructions
Metro fuel pressure ranges from 13 to 31 PSI. Higher if there is a clog in the return line. :O
This is higher than 10 PSI. The glass filter is only sealed with pressure on two o-rings on the ends.
