Silverado gas tank strap failure!!

[budnate]

not just the Chev's, Dodge guys have been having the same problem for awhile now..... [img]<<GRAEMLIN_URL>>/thumbsdown.gif[/img] for some reason it likes to hit the area behind the fuel tank first, it hangs tight to the frame rail, guess it gets wet and stays wet back there longer.

I just did front and rear gas tanks/filler necks/lower straps/rear frame shackles/all brake lines/Calipers/backing plates/rotors/rear wheel cylinders/ball joints/front inner/outer u joints/front fenders/rear quarter patches...all rusted from the really cool little white lines in the streets that they put down in the winter on my 96 F250.

I hate that stuff that they put down! [img]<<GRAEMLIN_URL>>/thumbsdown.gif[/img]

I'd say you got things covered Dave!

At work we just had an old Hino GC ( heavy duty toyota) loose a tank strap due to rust. I don't think our environment discriminates. The moral I'm picking up here is really for younger vehicles we all plan to own for a long time. I need to look intp rudtcheck and other PM steps.

An addendum to the prior posts: If your fuel lines and brake lines are rusty and you replace them, make sure you drop the tank and replace the sending unit as well. The factory fuel lines have a rubber section that is crimped onto an additional length of steel line that connects to the sending unit outlets. The other day after filling the truck up with diesel I saw a puddle under the front of the tank where it was running down from the topside. Looking through the fenderwell with a flashlight we could see that the outlets were corroded so I ordered a new sending unit for $70 from rockauto.com. We dropped the tank and this is what the sending unit looked like. We were also not happy with how the tank looked so I ordered a new one from rockauto which should be here next week. Lots of crud was in the bottom and after checking with a mirror inside we saw corrosion on the inside ceiling of the tank.

Here's the old sending unit:

Just went through the same thing on my `95 7.4 Suburban a couple of years ago. I'd really like to replace all the hard lines on the chassis, but no one reproduces them.

The aftermarket makes the full set of stainless steel brake lines. The fuel lines were relatively easy to do with just the lengths of modern steel lines. Not a lot of bends in the suburban, and the factory frame brackets keep them clipped into location.

I've only found lines for 4WD, and mine's 2WD.

I need to crawl under there and take a good look, see if I can fab them myself (joy).

When I bought my C2500 98 Burb from the original, senior owners out of Texas, when it was shipped to me I was astounded that the underbody looked like it just came off the assembly line. Still look pretty damn good today. That was 6 years ago with 74k on it.

Lucky man!

I bought mine in Florida in 1995 but we moved up north in '97 and then the salt took its toll. The body is still beautiful in its original Atlantic Blue and silver paint but the frame is crusty and the salt devoured the mild steel fuel and brake lines. Luckily the &quot;self rust-proofing&quot; option (leaking rear pinion seal) has rust proofed the underside.
