So I'm installing my ReNu'd fuel tanks,
and I kinda wish I didn't look into the
fuel filler pipe.
Ignorance is bliss after all... (yea, I know)
It looks like a old iron drain pipe.
I don't want all that rust breaking loose and filling
my fuel filters every 3 hours or so, sooo.
Are there replacements available,
alternatives?

First, I'd try yanking a pot scrubbing pad back and forth through it. Once the rust n scale is gone, if there aren't any holes, coat the inside with one of the fuel tank coatings. If it isn't salvageable the options are get one off one of the parts coaches listed in the swap meet or online; or any competent welding shop should be able to duplicate it using the old one as a model. If I were having a new one made, I'd try to source the pipes in stainless.

Johnny,

Save yourself work, plug both ends and fill it with molasses.

I just cleaned out rust scale in my VW Thing gas tank with plain Vinegar, and it was cheap. I figured it was also easier to clean up then the molassas method others swear by. Menard's near me, had gallon Vinegar for like $1.50.

It was amazing how well it worked. I filled up the tank, and let it sit overnight. turned it, flushed it, and dried it out. Pretty much everywhere the vinegar got to soak into, the rust came off our converted, or disappeared.

I did also do the por-15 gas tank coating on it, but that was mainly because the gas tank is still sitting out of the car for the past 6 month's, and i did not want it to rust up again. the por-15 gas tank coating is awesome stuff, but it is a process to get it to work right for you, and plenty of turning and twisting to get the coating to cover everything.

My experience with molasses as a rust remover is that it works, but is slow as molasses. :). It will take several weeks to get the results you want.

If you need a quick and very effective rust remover, try some muriatic acid. It is dangerous and messy, but will strip out the rust in a few minutes. If you are left with a few pin holes in the tube, they can easily be sealed by using copper plumbing soldering techniques. I just used this method last weekend to clean/repair a small engine gas tank on my dads old garden roto-tiller. Good as new now.

I certainly do not recommend the use of acid for the inexperienced or those not equipped to handle it. The risk of injury or accident is just too high. It is a messy process and requires a safe method of disposal.

my favorite rust removal page:

http://www.hotrod.com/how-to/paint-body/hrdp-0901-rust-removal-guide/

I have used "evaporust", and it works, but not as well as they claim. It takes a bunch of rust off, but does not leave the pieces I tried soaking/cleaning completely rust free. I feel the vinegar worked twice as well as the evapo-rust. I know I have at least $50 in wasted rust remover product. I did not go the muratic acid route, because as stated above, the safety, clean up, and disposal of that stuff was too much of an issue.

Unfortunately I have been giving myself an education in rust lately with my Vw Thing project.

I love using vinegar for rust removal, it works really well and is slow enough that it won't hurt the base metal.
Also, like Jon says, it's dirt cheap.
I'll just dump my parts in a 5 gallon bucket and soak them for a few days, a light brushing and they look like new.
Remember to neutralize in water / baking soda.

Then if you want to be really awesome you can do you own zinc plating at home with a battery charger :D

I've used a home grown Electrolysis process with great success. It might be a little difficult with larger pieces but with a little ingenuity could be done. Basically all you do is submerge whatever you're trying to clean in a solution of water and Arm and Hammer Soda Washing Powder and introduce a 12 volt dc voltage between the part and an anode. There are numerous vidios online that explain the process much better than I can here.
I'd think the fuel pipe could be inserted into a piece of pvc pipe and be made to work with a little thought.
Just another method that really works for cheap.

I'm looking into this electrolysis thing.
That's just a lot of rust...

Two thoughts:

1 - If some of that crud is dead fuel varnish it will interfere with rust removal. I would start out with some mechanical removal to get out as much loose stuff as possible. Then use lacquer thinner. Plug the tube and fill it up with thinner and see what you get out.

2 - to use electrolytic rust removal on that tube the electrode will have to be inside the tube as electrolytic rust removal is "line of sight" between the object and the electrode.

I have used electrolytic, Evaporust, POR products, white vinegar and muriatic acid for rust removal. If I was doing my tubes again I would use white vinegar. A challenge will be to get all the rust sludge out of the tubes after the rust removal. No product or process will give you clean metal. All will require post treatment cleaning. After I got mine cleaned out I did the POR coating and would recommend it. Nothing rusts easier than formerly rusty metal.

You can do all that, but the new fuel additives will do well, just put a
Large filter to catch the crud and gum and after 3 tankfulls, it will be
clean enough and leave the large filter in place and replace the element.
Place the filter by the Pump to avoid vapor lock.

Wow...Until the picture I thought you just had some scale and 3 dimensional rust, and removing/cleaning/recoating was the way to go. But now, unless that pic is an optical delusion, it looks like that stuff is on the verge of becoming a life form, like coral Laughing

! If I already had it out of the vehicle (looks like you do),I would use it as a template for making a new one if it wasn't available from one of the vendors or a fellow GMC'er with a parts coach.

I've used the electrolysis method on seat tracks and had great success-it'll clean inside and out of male/female sliding parts. I just threw the tracks complete in a bath of solution along with a scrape piece of steel for the anode. BUT, I've never tried it on something looking like your piece. Finding another tube might be the easiest way.
Good luck,
Hal
