Gas tank straps rusted & broke and need to replace. How do you get to the mounting brackets?

Lawn Mower or a Car ?

Remove the tank straps & drop the tank

If you have a pick-up,l tipping up the box, may be
easier,especially if it is old & the bolts are nothing
but rust

Usually the straps are bolted up at one end, and the other end is a kind of hinge bracket that the strap fits in. The bolts may be somewhat large, requiring a 9/16 or a 5/8 socket, possibly metric of about 15millimeter in that case. Use a 1/2 inch drive ratchet wrench, and plenty of lubricant or penetrating oil-you may encounter rusted bolts, so let the penetrant soak in a few minutes. Do one strap at a time-unbolt it and it will swing down. Then you can remove it from its front hinge piece, usually by twisting it sideways and slipping it out. Pretty easy job, although rusted bolts can be a challenge. And you will need the car raised a bit on jack stands, actually as high as you can get it to be comfortable under it, so be very safety conscious. Make sure it is stable before you get under it. Good luck.

Overtime, Jeep Grand Cherokee fuel tanks develop rust and accumulate sediment. This is especially true if the tank sits empty for a period of time. Rust and sediment can break loose and cause clogged filters. When the filter is clogged, the engine does not receive the amount of fuel required to operate. The fuel tank can be cleaned out; however, replacing the tank is easier.

2 Remove the gas cap.

3 Remove the fuel pump relay from the power distribution center under the hood. Look at the underside of the power distribution cover, and locate the fuel pump relay.

I know it can be a bear if the bolts and pins are rusted. Unless the new straps are OEM, some after market straps don't fit quite as well and you need Godzilla strength to manover them into place to get them pinned and bolted back up.
You shouldn't have to drop the tank as long as you do the straps one at a time. Get a floor jack, transmission jack or even a motorcycle jack and place wood under the gas tank and do one strap at a time. I used a second jack to help push the strap in place so I could push it into place on a 97 Dakota. Good luck and sometimes it goes smooth but, some times it makes a preacher say things they wouldn't say in church. :)

Very common problem with the muffler strap(clamp) breaking. It can be bought at any auto parts store & is easily replaced. It wraps around muffler & slides into a rubber mount bracket.

Depending on how rusted your Blazer is. You either remove the bolts from the straps or cut the straps off and replace both. Get a 2x4 and place of lift jack. The tanks should be about empty or a pain to lift. Lift the jack up to take some of the weight off the tank. Try to unbolt straps. If no luck. Get out a hand power grinder. Start cutting. That's about the only way I know. We removed my son's fuel tank off a 1988 GMC pickup last Sunday. Everything was rusted BAD The straps had to be cut. We didn't have any replacements. So we used 3 ATV orange racket straps. Worked fine so far.

Raise the car.

Loosen the fuel filler neck rubber hose clamp. Remove hose from tank. Insert tubing into tank and siphon out all fuel.

Undo the brake line bracket blots and move brake lines out of the way.

Undo the exhaust to muffler flange bolts. Exercise extra care if they appear rusted as they will shear off.

Remove rear seat and undo fuel pump cover. Undo fuel pump bolts.

Disconnect the fuel and return lines.

Support tank with a jack. Undo tank strap bolts. Remove straps.

Lower tank and remove fuel pump.

Drop tank and slide out over exhaust.

Underneath the truck,just in front the gas tank, there is a hose coming from the tank.
Mounted to the frame with a "strap" type bracket,
is your fuel filter. When replacing this you must be certain to orient the new filter with the arrow pointing toward the front of the truck or away from the tank.

replace mount these are common failure item let me know if you need details as to how to replace it

Normally it's just a matter of removing filler tubes from side, disconnect fuel lines & electrical connections at fuel pump/sender, undo the 2 straps, & lower it down.
