PanzerAce Posted June 3, 2008 Share Posted June 3, 2008 I've got a small leak somewhere on my fuel tank that lets fuel spill out if I fill my tank to within say a 5th of a gallon of the top, and I don't feel like waiting for an empty tank to fix the problem, so there's the question: How easy is it to drop the tank out of the car for one person? And what fuel lines/tank fittings/etc do I have to be careful of while I do it? Quote Link to comment Share on other sites More sharing options...
Vintage Posted June 3, 2008 Share Posted June 3, 2008 Well, its a cakewalk if its empty, not quite as easy if its got a decent amount of gas in it. Dropping it should be pretty easy with gas in it, putting it back up without help is the problem. I would recommend siphoning most of the gas out before you start. Oh yeah, its also a good idea to support it with a jack if you drop it with gas in it. Quote Link to comment Share on other sites More sharing options...
PanzerAce Posted June 3, 2008 Author Share Posted June 3, 2008 Don't worry, I'm crazy, not stupid I was going to support it with the jack for both the lowering and raising, since I have no desire to waste 4.50/gallon premium. Good to know it's easy though, since my roomates are all gone for the next two weeks, and I need SOMETHING to do to keep from going stir-crazy Quote Link to comment Share on other sites More sharing options...
naviathan Posted June 3, 2008 Share Posted June 3, 2008 Yep, just make sure you pull all the lines from the top of the tank and the filler neck first...it makes things easier to pull down...No I've never had any experience doing a tank by myself and thought the lines would be easier once it was loose...nope not at all.

Austin240Z Posted June 3, 2008 Share Posted June 3, 2008 Does yours have the drain plug? My 72 did, made it reeeeal easy once the tank was empty. Put a jack under it, undo all the lines you see. Drop it a little ways, and then get the lines on top of the tank. Then let her down. Should be as easy as that. Quote Link to comment Share on other sites More sharing options...
zedman240 Posted June 3, 2008 Share Posted June 3, 2008 Don't forget that breather line that's right at the top of the tank. I did my tank myself pretty easily. Worst part was installing it; when putting on the filler hose. While you're lying underneath it wrestling, you have to balance it on one knee with the other hand trying to get the rubber filler neck hose on! Just don't forget to install the top breather hose when it's time to install! Quote Link to comment Share on other sites More sharing options...
ktm Posted June 8, 2008 Share Posted June 8, 2008 Drain the gas. If you are so worried about wasting the gas, sell the car. You are going to spill the gas out of the driver side breather when you disconnect that vent line if you have over roughly 1/2 tank. Also, you will need to drain the tank if you using a jack to lower it, as the tank will bend very easily. The metal is quite thin and the gas will make the tank rather heavy.

Driving hard != wasting I'm going to be waiting to do this untill the tank is just about empty anyways. Quote Link to comment Share on other sites More sharing options...
Guest mr. datsun Posted June 15, 2008 Share Posted June 15, 2008 I've got a small leak somewhere on my fuel tank that lets fuel spill out if I fill my tank to within say a 5th of a gallon of the top, and I don't feel like waiting for an empty tank to fix the problem, so there's the question: How easy is it to drop the tank out of the car for one person? And what fuel lines/tank fittings/etc do I have to be careful of while I do it? I've found it's easier and a whole lot simpler to use a transmission scissor jack with a small 2X8 block of wood (so you won't dent or damage the tank). You can rent a tranny jack at any rental place (if they have one), and use a 1/2" rachet to lower and raise the tank slowly which is a god-send if you're working by yourself and can't get anyone to volunteer (we've all been there, right?). There is also a mixture you can coat the inside of the tank with to seal up any pin hole leaks. The stuff is sold at motorcycle shops (I don't know what it's called). However, it goes in as a liquid and you roll it around the inside of the tank and it sets-up (cures) as a semi-flexible coating. Many use this stuff if they custom build their gas tanks and it works. Check it out. Also, look at your connections at the filler tube and the filler neck itself for any splits in the hose. Once you've done all of this, coat the outside of your tank with bed-liner spray to protect the outside of it before you re-install the tank back into your 'Z".

jerryb Posted June 15, 2008 Share Posted June 15, 2008 I remove it myself ..and put it back. I support the tank with my knees while laying on my back....it a bit tricky but do-able. Just make sure its empty.....lol Quote Link to comment Share on other sites More sharing options...
JMortensen Posted June 15, 2008 Share Posted June 15, 2008 I can't see renting a tranny jack to pull a gas tank. Drain it and the thing will weigh 10 lbs or so. I take off all the hoses you can get at with it installed, then lower it down a bit and take the rest of them off. Not a very difficult job.

jeromio Posted June 16, 2008 Share Posted June 16, 2008 Hardest part of this job is the filler hose. I would cut and replace the various vent lines. They tend to be really dry and brittle anyway. Shall we bet on where the leak is? My guess is that it's right where the spare tire well touches the tank at the 3 o'clock position. It's a quick fix if you have a welder.

happynukes Posted June 19, 2008 Share Posted June 19, 2008 had a buddy with a 260 and was driving behind him as we were taking a turn and watched his fuel spill all over the road due to brittle or dried filler hose which wasn't hard to replace but you should have a drain plug as stated earlier by austin 240z just remove the straps and vent lines do you know where the gas is coming from?

Unfortunately, right now I need my car to often to have the time to drop the tank and JB weld the hole/replace whatever line is leaking. (I think it is a hole though, since it ONLY drips when I fill it up.) Quote Link to comment Share on other sites More sharing options...
Ga_Z Posted June 24, 2008 Share Posted June 24, 2008 Dropping it is now too bad. Draining your gas out will make it easy to do by yourself. The hard part for me was getting the filler hose off and put back on, other than that it was fairly easy. I had the car on jack stands and used a jack to hold the tank. Should be a few hours to fix it. Quote Link to comment Share on other sites More sharing options...

It's why I'm looking for a new job though that will give me more hours. I really don't have a choice about DDing it either, as it's my only means of transportation Quote Link to comment Share on other sites More sharing options...
blue72 Posted June 25, 2008 Share Posted June 25, 2008 I've dropped the tank by myself with only a cheapo floor jack and chunk of wood to distribute the weight. The only difficult part of the ordeal was getting the straps back up far enough while trying to balance/shove the tank back in place (I did it with perhaps half a tank in there). Now I've learned my lesson and know how to align them better, and try to run it pretty dry before playing in the little black room that spews fumes. No weight = easy 1 man job with some wiggling.
