Will this work? (or miserably fail)
I welded some 4 nuts (I said nuts ) to the inside frame rail and bolted the blazer conversion kit tank to the frame? Has this worked for anyone or is it destined to fail miserably ? Please resond without words like idiot and stupid (unless you feel its absolutely necessary).

Re: Will this work? (or miserably fail)
I'm sure it will hold but it would be my suggestion to run the straps with those bolts to help distribute the weight of the tank and fuel across a wider area.Seems to be alot of weight hanging on that seam otherwise. Just my .02 though.

Re: Will this work? (or miserably fail)
I dont see why it would not work, I would run straps too, the only thing i would think would be a problem is the bold tring to losing up since there is no lock washer

Re: Will this work? (or miserably fail)
Gasoline = 6 lbs / gal........not sure what the capacity is but probably not any more than 150lbs when full.
Looks fine to me......I would just check it occasionally. ..and if it does miserably fail, it will be far worse for the guy behind you than yourself!!!

Re: Will this work? (or miserably fail)
Maybe...or maybe not? The trucks going to be lowered 6" at the rear. Hey, at least I won't lose my gas. 20 gallons of unleaded is about as expensive as the tank itself here in California.

Re: Will this work? (or miserably fail)

Re: Will this work? (or miserably fail)
Where did you get the tank? I like the set-up. Mine was converted by the PO and the tank almost drags the ground. Needs a fix........

Re: Will this work? (or miserably fail)
Well I would use the straps. The lip on that tank is not designed to take the weight plus the vibration of the tank full of gas. Also add to the fact that your frame is flexible and is constantly moving (this is why your frame is rivetted together, not welded) I think it won't be long untill you either break the weld in the flange, or crack it bad enough for it to start leaking. The engineers designed the tanks to be strapped in for a reason. WES

Re: Will this work? (or miserably fail)
Wes, from classic heartbeat pickup parts, can more than likely get you a good deal on one too. You can find a link on post #15 of this thread.

Re: Will this work? (or miserably fail)
I agree with Wes... esp when you consider that today... 40 years later, they still do it the same way.
Your idea looks very clean and would be awsome on a show circuit truck, but if you ever put fuel in it, I would really consider straps, esp in a state where personal lawyers are more common than personal responsibility. |

Re: Will this work? (or miserably fail)
The aluminum tanks are a little different than the steel tanks. Most aluminum tanks are designed to bolt directly to the frame. The reason is they do not use the flange as a seam too. Most have thick angle stock welded to them that can take a little more flex. I would not want to be in an accedent with one though, because all it would take is one frame rail to be pushed back a 1/4" or so to tear the tank out. WES

Re: Will this work? (or miserably fail)
in your state, I would too. if it doesn't have a DOT certification number for that model number vehicle, the laywers would have fun batting you around like a cat with a ball of yarn.
Same thing if someone gets hurt from the fuel after rear ending you. |

Re: Will this work? (or miserably fail)
Exactly why I have my truck in an LLC. Among other things.
Privay and Asset Protection. The only remedy is the insurance pay out. Exactly where I want them to go. I can't stand being batted around like a toy. Tim

Re: Will this work? (or miserably fail)
71Tahoe: Is it just the camera angle, or isn't that tank low enough that a flat (especially a blowout) will put the tank bottom onto the pavement ???
I'm planning a rear tank, too, but it looks to me like it really HAS to be mounted higher up to the bottom of the tank than an imaginary string-line drawn bewteen the two rear wheel rims, or a flat on one (or Heaven forbid, both) of the rear tires would cause you to drag the bottom out of the tank, while you're also making lotsa sparks. A bad combination............... |

Re: Will this work? (or miserably fail)
I'll be installing my tank kit soon, so this thread is timely.
I think it'll work fine. I also think you've touched on most of the major issues, strength, safety, appearance. The thread does cause me to think though. Car makers have to build their tank supports to withstand all kinds of crashes. Though a little unsightly, straps and J-bolts will support the belly of the tank well, but offer the added benefit of releasing the energy of a rear end collision more slowly (lower G forces) without tank rupture. A "hard" mount like yours, in the very unlikely event an 18-wheeler rear-ends you, is more likely to rip the tank open and spew fuel. On the other hand though, under a lowered pickup bed I think a mount like yours is less hazardous than the same setup would be under a Blazer or a car (and a whole lot safer IMO than the truck's internal tank). Finally, because this thing isn't going to be a daily driver plus you'll be driving it more cautiously, statistically you're less likely to ever encounter such a situation. Overall I like your approach and just may use it myself. Thanks.

Re: Will this work? (or miserably fail)
Accedents can happen at any time. Driving the truck less and thinking that well I am on the road less is only playing russian rulet with your life and any other that may be involved in an accedent. Let's remember, accedents involve more than one vehicle, unless you run it off the road or something like that. Gas tanks are strapped for a reason. Even semi trucks strap their tanks to the truck. I believe that the bolted aluminum tanks can take a better hit, however it will rupture faster than if it was strapped in. Longhorn Man hit on another point also. Law... I am sure that there must be something in the law books covering this issue... Why else would manufacturers go through the added expence of strapping them in. WES

Re: Will this work? (or miserably fail)
This is what I wound up doing on my son's truck.
Got rid of tabs on the driver's side of the tank and rounded one end of the square hole with a dremel Drilled and tapped an aluminum plate 7/16-14. It doesn't show it but the final assembly got nuts on the back to lock the bolts 1 1/2" spacers Had to drill 1 extra hole in the side of the frame for the forward j-bolt. I used an old inner tube from a 26" 10speed bike between the frame/tank/straps I think next time I'll get rid of the tabs from both sides and insert a long bolt down through the frame on the passenger side, tighten the straps and lock with a bolt on top and bottom of the strap. The j-bolts were a real pain. Last edited by 71tahoe; 07-29-2007 at 02:09 PM. |
