Leaking gas

[Aphonechanh]

Hello all. I have a 93 skyline gtst. Gas leaks from the left of the white nipple that you see in the picture. It goes from full tank and leaves me with a quarter tank and does this within a matter of hours.  When it leaks its a small steady stream until my tank is down to a quarter. I plan on putting the car on a ramp this weekend but wanted opinions on where it may be coming from? A leaky hose,  seal? I'm mechanically inclined but is this an easy job or should I leave it to a garage to fix? Any help is appreciated. Thank you!

Looks like the front of the tank is wet. If so, your leak is not where you think it is. It's just running down there and dripping.

As to whether you can fix it or not......how are we to know what the hole looks like?

When my tank leaked it only leaked until about 3/4 tank. Turns out an evaporation hose on top of the tank, a breather hose attached to the filler hose, and the fuel pump o-ring had all gone bad. Replaced them all and it has been perfect. Not sure how different a GTS tank is from a GTR. If your tank is leaking all the way down to 1/4 tank then it's probably a hole somewhere down low, you might be able to see it without dropping the tank. 

Dropping the tank itself isn't too hard to do in your garage if you have a buddy and can be done in an afternoon. There's a post on here that gives pretty good directions with pics. Of course a garage with a fuel tank lift would be able to do it much faster. At least since so much is leaking out you don't have to worry about draining/siphoning out (as much) fuel first, but keep in mind that even at 1/4 tank, gas is heavy.

Have seen some leak from the seal between the filler neck & the tank which would probably leave it with around 1/4 of a tank

jesus why are you trying to run your car on gas instead of petrol? Our mate Mark converted his GTR to gas but you can't expect to just put gas in the tank and not have it waft back out????

It's NOS bro'.

Update: well it seems that it is leaking from the weld seams. it wasn't from rusting out but just came apart from a bad hit. Ive tried to look for gas tanks specific to that model but should I expand my search to other models? If so,  anyone know what other tank will fit in there? I can have the shop weld the seams back together. If I get it welded, will it hold better or just the same shit?

It can no doubt be welded back up. But make sure you take it to someone who knows what they're doing. Often radiator shops will know what to do. You have to drain and clean and fill it with inert gas to avoid the risk of denting your skull.
