Well tonight i was driving home and it was 1am and i was going around a roundabout, and i might just add my r32 gtst has a mini spool, and there was noone around so i dropped second and it went BANG, and nothing... so i drove about 20m and realised car is pullin to one side. So i pulled over and as i came to a stop i saw a sheared bolt with a nut on the end roll past me... And i looked behind me and i had already lost alot of fuel, so i shut off the car instantly! Then look under car and found my rear right axle loose, i dont know if its snapped at this stage as it was dark, but i hoping its just the bolts. But anyhow the axle cut through my fuel tank..

Has anyone ever welded there fuel tank befor? Is it necassary to pressure test etc.. What kind of process did u go through.

Any input welcome, apart from the your an idiot deserve it.

Car has been running minispool for well over 4 years that i know of.. and this is first problem

cheers

Sad to hear that mate, but i thought Skylines fuel tank were made from plasticish materials? Or maybe that was introduced on R33's.

on another note, NEVER EVER try to weld a fuel tank or barrel or perhaps even a little can as it maybe explode in your face. There are still traces of fuel on the metal even if its dried. My father was a welder and has worked in the field when he was young, hearing him tell me stories of oil/fuel barrels exploding when welding freaks me out, some of his co-workers lost parts of their bodies.

yeah thats what im worried about. I have read on it befor there is ways around it... maybe will tank with water while welding... but u would have to make sure u cant get ur welds wet etc.. i dont know. there has to be a way. I am a fitter and turner but i have never had experience in welding tanks. Might need alot of ventilation too!!

Just buy one from the wreckers, it will work out cheaper.

A friend welded fuel tanks, all sizes from cars up to petrol tankers.

He works out the volume then floods the tank with Argon. Hearing his stories about welding inside petrol tankers, walking around with fuel up to his ankles, wearing all the breathing gear, frightens me to death...........

haha go the spool! i wouldnt recomend them in skylines though, i love mine but im driving a VL. anyway, but a new tank, and find out what else has let go (dont forget something has put the big gash in the tank)

if u realy want 2 weld the tank ive being told 2 have the tank in a steam cleaner 4 at least half hour 2 get rid of the fuel vapours. but i still wouldnt try it. with the amount of skylines out there it would b cheaper 2 get a second handy and get it cleaned 2 get rid of the crap inside it.

If you don't have the capability to purge the tank (some inert gas or another, though argon is the common one) don't even consider it. Explosions are bad.

The tank isn't under pressure, but you do need to test for leaks if you do weld it up obviously.

didn't even know you could get a minispool for 32's. I know a guy with a 31 who swears by the $100 ebay ones. if you go through 10 it's still cheaper than a 2 way.

haha yeah i got one in the 32. There is nothing wrong with the spool haha its just breaking other things. I got the fuel problem sorted out now. cheers guys

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
