John,
If you feel like driving down, I will show you. I have plenty of brazing rod with flux on it.  thumpup)-

Thanks Bob! I'll see if i can make it this weekend if you have time on saturday morning.

Sounds like a good club how to, like we used to have years ago.  whistleegi whistleegi

If you dont clean it out properly and fill it with water the fuel will FLOAT on top of water ClOSER to where you will be brazing......

I emptied the tank on sunday. It will air dry outside of the car till saturday. I figure it should be good.

[Baha (Shawn)]

Its the vapors that are explosive.
I've brazed tanks before. after rinsing & drying the tank, I run air into the tank as I braze it.
Constant airflow dilutes any vapors that might be present.




I just read what I wrote... I don't mean pressurizing it...
Just run an air hose in the tank. The air vents through all openings

so Bob, you busy saturday morning?

[Bob(Herbie)]

 I will be here. What time do you want to come over? It should be an easy fix. It will seem familiar to me as I haven't had any students for a few years!  %$oldcit

[Bob(Herbie)]

I agree.. Reguardless how much you think you cleaned or cleared the tank of fuel, it will never be completely vapor free. Fuel Tanks actually absorb the vapors..

 It is very hard to find a shop that will accept a fuel tank to be welded and many will not touch them.

 I have welded several tanks over the years, car, bikes, boats, etc. The bottom line is that if you don't prep them correctly things could go boom.

 This works for me. Rinse the tank well with hot water and a decent dish soap, actually Hot water and a little hand degreaser works great. Shake and rinse several times. Then rinse with hot water, followed up with some vinagar.

 Brazzing is good and bad. The good is that brazzing will flow into cracks and crevis, but the bad is that to do so the sheetmetal stretches and weakens from the heating and cooling causing stress cracks to sometimes open at the outer edges of the brazed repair at a later time.

 The best way to do a controlled heat weld is TIG welding, but that is almost a art.

Be safe, flare ups are to be expected just be sure that the tanks has openings so that the flare up will have an escape

One other method that works is carbon monoxide will neutralize flareups and extinguish fires. I have heard of welders welding tanks with fuel in them using this method, although doubt that I'd like to be within a 1\2 block watching?

 If you get stuck and need a hand let me know..

Felt like doing some work on the bus... yes I do get those feelings on occasion. Decided it is time to put the missing Transporter Trim on that Yucel gave me... probably almost two years ago.  ?/banghea?/ The problem was that the screws were stripped, and I thought that I needed to get a left handed drill bit to get them out. So I went to Harbor Freight thinking that "I'm going to go in, get the drill bits and leave" didn't happen. I got drill bits, channel locks, and a pop rivet gun (for my Coleman Grill rebuild project). So I started with the channel locks, and was mostly successful, I got both of the corners on.  :jump4jo": Going to have to drill out the old screws to get the missing side piece on.



Gotta wait till Matt comes home to let me know where the power drill is. I think he hides in on purpose.

Went over to Shawns garage this morning. Bob came over to show me how to braze metal. I had been losing my mind trying to find a gas drip under the gas tank. I tried replacing a cracked nut, replacing the fuel valve but still a drip. I narrowed it down to a hole in the tank valve outlet. After bringing it to Shawns garage, Bob had me brush down the bottom of the tank at the outlet and this brought to light the 2 small holes in the tank itself. Shawn made the entire procedure into a video and I'm sure the link will be up soon. Went home, installed it and what do you know? No leak. Thanks Bob and Shawn.

on a side note- Shawn was digging through his parts stash and found a horn. Wasnt sure if it was 6 or 12 volt but it is worth a try. Installed the horn and guess what? BEEP!
It's kind of a weenie sounding beep (high pitch and not very loud) but at least I know it's not the wiring. Thanks again Guys!

Lots of caviats when repairing a gas tank. John washed the tank with hot soapy water 3 times. Then he hooked the shop-vac hose to the output and blew warm air in the tank till it was dry.

When John brought the tank over I smelled the inside and almost no smell was present. Still, I ran compressed air into the bung while we brazed.

Little blurry...Sorry




All done, it looked great. Ill put the video together and get it up on youtube ASAP

Tried starting the Cabriolet with the jumper box, battery might be too low to start with a jumper box. Not in an easy position to start with cables. Might just run the battery to Pep Boys and have them test it and charge it up.

[vwtrike (Rich)]

I charged the battery. Next time we have a warm day I'll try to find why I'm not getting fuel to the filter. :confused04:;
