Yeah mate, see page 2 of this thread. Unfortunately the line is connected to the hard line of the vehicle not the fuel tank. Tank is already off. If the fitting wasn't damaged I could just do what I need to do and put the tank back on, but my luck is not that great.

Okay so I've pretty much given up trying to take that damaged pressure fitting to the line off, which means I'm now left with 2 options: 1. Replace the whole metal fuel line 2. Cut the damaged end off and put a new fitting on I'm inclined to replace the whole fuel line, however if someone here can tell me if there is an easy way to repair the end, then I would consider doing that. So far my research shows that I would need special tools to crimp the end and apply a pressure fitting, etc etc. Tools I don't have. But I have seen some repair kits...just not sure what to look for exactly. Any help/advice would be much appreciated.

Dude that is awesome. I'd very much like to give that a go. It looks like I can order directly from that website, but as you say it's not very cheap. However a new tank would probably be more than that. I'll hunt around though...thanks heaps Edit: This looks like the same thing and is available from Autobarn: http://www.kbs-coatings.com.au/product/auto-fuel-tank-sealer-kit/ https://www.autobarn.com.au/kbs-workgear-repair-kit-fuel-tank-di07156-5140

Haha wouldn't that be great...pop in and get whatever part you need. No it isn't, but I got the fuel tank out last night with a friend. That pesky fuel hose is still attached to the fuel line, but we got the other end off attached to the tank. I have to replace the fuel hose because I busted the other end. A quick inspection of the tank shows there's a little rust inside, that is why my friend said I should look at maybe getting a new one, but I don't think he knows how hard that is. I don't really see the point of getting another 29 year-old tank that has been sitting outside in a wrecking yard. I think it would make more sense to try and restore mine...or maybe I just leave it! I'm not sure how bad it has to be before it's replaced. I can take photos...

That sounds like you need 3 hands, but I'm sure I'm misunderstanding what you said Anyway, just a short update. Had a mechanic mate come over tonight and we tried and tried, but that bolt just wouldn't budge. He said he's never seen that before. He even used an ice spray to break the rust, locking grips as you suggested, you name it. Turns out he was able to get everything else off and slide the tank out, then that gave him access to the other end of the fucked line, and he un-did that bolt with no problems. Now that the tank is out, I have much more room to try and get the other bolt off. I'll just keep trying until eventually it either comes off or it breaks off. Either way I have to replace that line now and hopefully the metal fuel line it attaches to isn't stuffed. The other thing he suggested was to replace the whole fuel tank. Does anyone know where I can get a new fuel tank from that will fit the Corolla? And out of interest an approximate price?

I have proper spanners now and still no luck. I guess I keep trying until they crack

Thanks for the info. I had already emptied the tank, so this was my next challenge. It’s a tough nut to crack (pun intended) I only had a shift spanner so when I was trying to loosen the nut it slipped and I think I twisted the whole thing. Pretty sure I damaged the pipe inside as now the body of the nut spins somewhat freely and a little bit of fuel dripped out. Both nuts are like they’re welded together, so tough! Tried lots of WD40. Just so I’m sure, which way should I be turning the smaller nut? Looking at it from the left in the pic I’ve been turning it anti-clockwise. Is that correct? I'm going to buy some open end spanners at the end of the week and try again.

Okay so after a bit of digging around, I discovered I do in fact have to drop the tank. After looking at some youtube videos, it doesn't seem too hard. There are 3 fuel lines to disconnect, then the fuel intake hose and then the straps that hold the tank to the car. There is one fuel line I can't disconnect because I'm not sure which nut to unscrew. In my pic there is the nut with the blue arrow and the other larger nut with the red arrow. Which is the one I should be unscrewing? What are these fittings called so maybe I can search online? They are high pressure fittings as far as I can tell. I've attempted to undo both, but without knowing which way to unscrew them or which nut, I'll just damage the line, so I stopped.

So I attempted it, but I can't actually find where the pump is! It wasn't where I thought it was, which was under the back seat where the access port is and where the wires are going to. What I pulled out was the fuel gauge sending unit, but no pump inside :( Does anyone know where it's located on an AE92 Corolla? Do I have to drop the fuel tank (please say no)?

Fair enough. Do you have any guides on how to remove and replace the fuel pump, and is this even something I should attempt myself? I've done a bit of a search online and on this forum and couldn't find a step by step guide anywhere.

Haha true, I like to keep a bit of mystery ;) Idk, just to see if it will work and that is the problem before I spend any real money on it. I actually have the OEM pump somewhere in a box, so maybe I can swap it out just to test it!

Who said anything about it being standard? It's making around 310HP at the crank. A 500HP pump might be overkill, but that's what was put in by the performance shop.

It's not a standard pump. It's a Walbro 500HP. That might set me back $150-$200. I've seen a few youtube clips where mechanics have been able to revive a seized pump...I wonder if it's worth trying.

Okay so turns out stupid me wasn't grounding the negative properly when testing. Retested simply by disconnecting the grey clip to the fuel pump with the 2 wires, then checking 12V at the terminal. The pump is getting power when the Ignition is ON. So now it looks like it's definetly the pump itself that is not working. So what are my options now? Any way I can revive the pump?

Okay so this is what I have done so far after following the guides you posted (thanks!): 1. Shorted the terminals Fp and B+. Pump didn't turn on. I checked power going through the B+ terminal and all good. 2. Checked fuses EFI 15A, and AM7.5A and EFI main relay. All good. Relay closes as expected when powered on. I was unable to check Fusible link 1.25B as per the guide, because I don't know where that is? 3. Checked full operation of the Circuit Opening Relay as per the guide and it works. 4. Lastly I checked whether power was going through to the pump itself when Ignition was ON and I didn't get a reading? As can be seen from the pic below, I was getting no power to the blue/black stripe terminal, or the white/black stripe terminal (located underneath the back seat where the pump is). Should I be getting power come through on one of these terminals when Ignition is ON? I checked the white connector terminal too and no power to that one either. Indicates there's a break somewhere doesn't it? How can I test the fuel pump itself on a battery? Do I leave it in the tank and just hook up power to the blue/black stripe and white/black stripe wires?

So I found the diagnostic plug and it looks like this I’ll try and clean it up and hopefully it will still work for me

Mate you are a legend. This is exactly the kind of thing I was after. I did read elsewhere that I could short the Fp and B+ terminals (somewhere) to run the pump without actually pulling it out, so I will definitely try that and report back. Car has been sitting there idle for too long so it wouldn't suprise me either. Thankfully the actual engine hasn't seized. Yep should easily be able to test the Circuit Opening Relay as well while it's off the car, at least to see if the switch inside works. I've already found that one under the dash and it's easy to get to. I've heard replacement can be ~$100?? Not sure how true that is, but I'll cross that bridge if I have to. Thanks again for the info. I'll report back with my findings.

I'm pretty confident it's the pump, but thought it would be easier to check fuses first before pulling the pump out and possibly causing more damage. After writing my post I did find a few wiring diagrams that showed a Circuit Opening Relay under the dash where the ECM is. Carbon can build up on the contacts which then stops it from making a proper connection. After cleaning that with a bit of sand paper I thought I would have solved my problem, but alas still the same issue :( If there are no other fuses to check, I'll find a tutorial on how to pull out and test the pump. Thanks

Hey everyone, Thank god forums like these are still around. This is my first post on this particular forum, but I have been a member of older ones for over a decade. Have also been a long time Corolla owner (have had a AE82, still have the 92, and had a Sportivo). Anyway enough of the history lesson. My modified 92 has been sitting in my garage for 7 years. I have turned the motor over at various times and it’s always ran perfectly. In the last year I’ve had trouble starting the car and I really want to bring it back to life. The motor turns over, spark plugs spark, but the motor doesn’t start. My best guess is that it’s the fuel pump, as I can’t hear it turn on (it’s a Wahlbro 400hp pump). I’ve tried to find the fuse for the pump but no luck. My online research says it’s part of the EFI module, but maybe someone here can tell me for sure?
