How To Clean A Rusty Gas Tank W/ Acid and Baking Soda From Home Depot - Sealing After is Recommended

[@darthbeenis3100]

I have an older Subaru Forester and removing the fuel tank was probably as difficult as removing the engine itself. The fuel pump diaper (strainer) kept getting clogged because of all of the rust. I managed to follow your advice without removing the tank by using a paint mixer drill attachment to agitate the acid/water mix. The tank was super clean and it was followed up by a soap and water cleaning after. It flash rusted the next day because I did not let it dry and used ethanol gas for the first refill. To any other viewers that want to try his method, follow it 100%! Thanks for posting this!

[@BroncosandPartsGarage]

Very cool. Glad it helped

[@thomasd9237]

Personally, I would have stuck with the Marvel Mystery Oil. It's been around 100 years for a reason ☺️ Thanks for posting this, I'm restoring some vintage gas cans that have been sitting. Gave me some good ideas 👍👍

Thanks!! Be careful. Use protective gear.

[@JohntheStriper]

Thanks for this. I'm going to do my 67 Dart tank tomorrow. It's been sitting for 16 years.

[@BroncosandPartsGarage]

Glad I could help. Be sure to line the tank too. Keep adding baking soda until it stops fizzing to neutralize the solution. Also- Costco sells huge bags for $7

[@danielploy9143]

@@BroncosandPartsGaragewhat does line the tank mean please?

[@3rdcoastobs467]

right on time. i need to clean both my tanks on my 93 Lightning I'm restoring. Fairly certain the gas is from 2016 as the previous owner stopped using the rear tank after the fuel pump supposedly went out. I'm still fairly certain is was his ECU though, it was corroded to hell and when they gave up on the truck it wouldnt start so i replaced it along with a few other things and got her fired up after years of rotting. Sorry went off topic, thanks for the video, ill be hitting up your amazon links for sure!

Be carful. Use safety gear

Great video. Debating on buying a new tank or cleaning the one I have. This video was extremely helpful. Thanks!

[@BroncosandPartsGarage]

Glad it was helpful! If it’s a rare tank, clean yours. If it’s a common reproduction, and shipping is cheap, buy one.

[@hugopoirier7746]

Thanks Chris. I'm not a mechanic for 5 cents, but I'm having problems starting up my 1990 EB, so your video is just right. I can't hear the pump anymore when I start it. I'm afraid I have to do the big tank job. First of all I have to check all my relays and kill switch. No gas pressure. Here in Canada, Quebec, it's very difficult to find parts like the unit in the tank (pumps and sendind unit. Nice work and thank you for your videos and your help.

[@BroncosandPartsGarage]

No problem.

[@brunothehumble]

its kind of funny. my original tank was completely fine when i replaced it a couple years ago. it only got swapped out because of the dent that was costing me around 2 gallons of capacity. it was amazing that it was completely clean inside and it was around 30 years old when i swapped it. gotta keep em moving and a good cap on it.

[@BroncosandPartsGarage]

That’s awesome. Keep em full. Less rust!!

[@timtaylor6068]

Need advice. 90 bronco eddie bauer fully original. suspension for city driving mostly, steering wheel moves a bit up and down, piece between the headliner and the top like molding, new rear bumper system that hold spare...old tire rack bent the quarter panels. Thanks for any advice to solve these last few issues.

[@BroncosandPartsGarage]

Steering wheel sounds like bushings. If your tire carrier has damaged your rear quarter, I’d simple remove it as the metal has been compromised. I sell the topper trim as well

[@WadeRuledge]

I am working on removing rust from a fuel tank right now using evaporust. I drained the evaporust and rinsed out the tank but noticed flash rust very quickly. How did the seafoam spray work afterall? Any flash rusting happen?

[@BroncosandPartsGarage]

Seafoam, did stop the flash rust. We installed the tank then topped off the tank with gas. The Acid removes some of the galvanized coating. We pulled the tank 8 months later. Still no rust. That said, I would still coat the tank after cleaning or just make sure I didn’t leave it empty for long periods of time. The seafoam obviously is washed away with first tank of of gas. Bronco tanks are $100 new. So easy to swap. Older classic cars and trucks, this video is a lifeline.

[@rjensen4896]

Thanks for the video man. I have a 79 rx7 with a clog in the fuel pick up line thats brazed into the tank (car uses an external fuel pump), so I'm hoping this will work. Do you know if I should use POR15 to seal the tank?

[@BroncosandPartsGarage]

Por15 or other sealing chemicals. I’ve used some off brand years ago

[@icannevergetthistowork]

I have a 13 gallon tank off of my 1941 tractor. It has rust in the entire tank. Would one gallon on each work with rolling it all around so that the entire surface of the tank is hit, or do I need to add more. Thanks!

[@BroncosandPartsGarage]

I think one would do it. Maybe try 30% vinegar. Mixed with some water. Less acidic. Add some nuts n bolts and shake it. Wear protective gear.

[@SGCXD]

Do you have any tips on cutting an access door to reach the fuel pump from the inside so you don’t need to drop the tank to fix or replace the pump?

[@BroncosandPartsGarage]

I’m not a big fan of that. It’s a great time to drop the tank clean out your skid plate and prevent any type of corrosion. I would post it in the Facebook group broncos and parts Garage if you’re not already a member, and I’m sure someone has the dimensions if you go that route

[@SpeedyWings2323]

“If you were ever a kid” 😂

[@BroncosandPartsGarage]

Lol

[@josephglaser9276]

To clean more of the tank, could you add 3 gallons of water in 3 gallons of that acid?

[@BroncosandPartsGarage]

…. You could. Usually the entire tank won’t rust, just the bottom. I’d slosh it around. Safely. It will chew into the galvanized finish eventually. When your done, pout in the baking soda until ALL the fizzing stops to ensure you neutralize the acid. We did not reseal our tank but we had no issues. I still recommend drying and fogging it asap.

[@danielploy9143]

Damnit man that was a good video on getting the rust out. I want to do this on a generator fuel tank holds 5 to 7 gallons. Do you have a go on how I could get all the water out, cannot get hands in there. Maybe let the sun dry a few hours pretty hot out right now. I plan on using the marvel oil should the inside of tank be completely dry first?

[@BroncosandPartsGarage]

Yes, used dry compressed air to avoid flash rust. then coat with a light oil like you have planned. something that can be added to a gas tank normally.

[@kornmdb]

I have a 94 Bronco. Any idea what size the fuel lines are. They need replaced.

[@BroncosandPartsGarage]

Check with Jeff sprinkle Graveyard in Michigan. I know they sell the rear fuel Lines.

[@LordKenjii]

Great work. I’ve heard dropping the tank is a pita. If I’m dropping the tank without a lift does this make it infinitely harder?

[@BroncosandPartsGarage]

No. Just make sure tank is as empty as possible. Use a floor Jack to lower tank. Get a buddy to help.

[@slider2894]

Oiling inside the tank won't hurt any of the injectors or anything?

[@BroncosandPartsGarage]

The compound we used was actually designed for cleaning internal combustion engines. Including fogging engines. Link in description. Sea Foam makes some good stuff.

[@Trevor_Hall]

Hey Chris, love the videos!!!! I have a stock 92 bronco and I was curious if 33s would fit without much rubbing. Thanks.

[@BroncosandPartsGarage]

They will rub your front spoiler lip and they will rub the edge of your front bumper. Depending on your offset they could rub your radius arm. Lots of people either space there bumper out forward or they trim the actual corner of the bumper

[@Trevor_Hall]

Thanks for the info! I really appreciate it.

[@dwaynekalloch1732]

Is the Bronco maf, or SD? I have a 95 5.0 with sd,and am curious about performance upgrades

Being a 351 and a 95, sadly it’s speed density. Your 95 should be an MAF!?

Great video! Can I ask how sealing the tank with the Seafoam has held up? I noticed in the description you said to use a product like Por15. Like you I have a brand new can of the the same aerosol Seafoam I'll use if it worked for you.

[@BroncosandPartsGarage]

Thank you. We used the seafoam spray JUST to prevent the tank from flash rusting. Had we had the por-15, we’d of coated tank right away.

[@BPattB]

@@BroncosandPartsGarage so what I did was immediately after vinegar washing the tank and blow drying it I used a bottle of Lucas safeguard ethanol fuel conditioner swirl it around the tank and then used a bit of the seafoam. But honestly I don't think I needed to see foam after the Lucas ethanol treatment. After swirling the Lucas ethanol treatment I drained as much of it as I could and put the tank in and then put 12 gallons into the tank. No issues I'll update you if the tank rustest out on me.

[@customcutter100]

Really not any rust in that tank. All the acid did is eat the coating off of the inside of the tank, so now it will definitely rust as you didn't coat the tank. I would have used acetone or alcohol to remove the gelled gas.

[@BroncosandPartsGarage]

What coating are you referring too? We’ve used the technique on much worse tanks- usually in instances where replacements are not available.
