try a vise grip after using kroil oil and a heating torch several times......if it snaps off flush then drill and tap.btw' easy outs just never seem to work for me and they are a royal bitch to get out once you break them off !..HTH

another option John if you cannot get vice grips on it is to weld a hex nut to it and extract it that way......beats overhead drilling; but if you have to; go carbide.HTH,

I think the tank should be tight against the body of the vehicle. If it isn't it will rub the wrong way against something causing abrasion and finally a hole. Most fluids is about 8 pounds per gallon and all that weight in a full tank will eventually bounce around causing metal fatigue somewhere along the lines. I did mine (62 series) and dropping the tank is something I would not want to do twice.

I'm with "archie", you're going to have nothing but problems if the tank is not secure.

If you can't do the overhead welding trick, grind flush & use a right angle drill. The back of the bolt is inside an enclosed channel so you can't get to it from there. I remember breaking off many bolts back under there, then I cut all that low hanging rusty junk outta there & fabbed mounts where I could get to all the bolts & no hidden areas anymore

Lil'John, I feel your pain and don't have any different advice. I'm hesitant to drop mine after reading this but have a leak that appears to be on the left side top of the tank, probably not the filler hose as I originally thought nor the suspect vent hose that I fixed. Since you have the tank out would you post a pic so I can refer to it in chasing my leak?

One man's misfortune is another man's opportunity.

TIA!

On mine, my tank had a crease in the top that was leaking, I guess resulting from iron pigs flying....

Front range, I'll take the lazy route and put a bunch of fullsize pictures here:

Currently having an issue with the above. Hope to have it resolved in the next day or socensor: website junk)

If you need any other specific pictures, I can retake them.

You can try:

also there is 27-31,33 and 34

Be warned, these are like 1-2Meg each.

Size isn't a problem but I can't access the first link - Forbidden!

Wow! That's a lot of connections, thanks. Looks like I have a lot more checking than I would have guessed.

ran into the problem that all 4 vents were capped on mine along with the line to the charcoal canister........this created a major problem 'cause when the air inside the tank expanded it pushed the gas which was below the air pocket OUT through the unvented gas cap and from there to the exhaust; there are some pix on "Rookie Intro of my new pig" post #177 of Ryan/Scott/Goebels pig gas tank cut open showing how those 4 small vent tubes that go to the air fuel separator are very well thought out and very interconnected............the question in my mind is..........how many vents do we need am also enclosing pix of what happens after the vents are ALL capped off and after driving a good 40 miles and letting the pig sit for a couple of hours...the air expands above the fuel and pushes it OUT..problem solved temporarily by connecting the 4 vent hoses to the fuel air separator and this to a junk yard 2 inlet charcoal canister venting the outlet into the DS "D" pillar about midway up the pillar..HTH

Lou

Lou, you need all 4 vents. One to each corner of the tank. That way, regardless of which way the truck is leaning when parked, one of the vents will be at or above the level of the gasoline unless the tank is right full in which case the vent won't help anyways.
