That title got your attention didn't it?
Dammit! Last week I finished the install on my Aux Tank and got the transfer pump all wired up. So I filled it with gas and flipped the switch to make sure everything worked alright, still leaving some in just because - fast forward one week, I get home from a business trip and smell gas
it's a slow leak, probably just a pinhole, behind the mounting bracket - I can see a few slow bubbles of gas from where the bracket meets the tank. Before I installed it I took a good look inside and everything looked clean and rust free - the only rust at all was where the bracket welds were (heat cooked off galvanizing/coating). Since I can't afford closing on the property we just got and buying a new NWMP tank ($630 + shipping), I'm thinking I should be able to weld all the way around the mounting bracket - effectively sealing the leak . . . hold on now, I'm not talking about just running a bead straight to the tank and blowing myself up. The way I've heard to go about this is: drain the tank, rinse with ammonia, let it air out a bit (blow air into it with a shop vac), completely fill with water and then go to town and run a fat bead of weld to it.
-or- I could try to undercut the area between the gap in the welds, clean it and JBWeld it. My only issue with this is that I'm unsure of how long that will hold since gas tanks usually build a bit of pressure in the hot sun.
Any other suggestions or am I just being cheap? Honestly, if I can't fix it, it'll probably end up scrap metal
