Carburetor issues and today's fuel
« on: February 20, 2021, 02:27:45 pm »
I've been noticing a surge in carburetor issues with truckers out there and wanted to touch on an important matter that many truckers overlook and that is: today's fuels. Today's fuels contain alcohol (E10 and E85 and so on) which attract water and is corrosive to aluminum and plastic parts inside the carburetor especially if it's been sitting for a bit. Fuel quality and the ingredients in it have changed and can cause damage to our old trucks. It's something to be aware of. I posted an article that talks about it in more detail. Keep your trucks alive!

    Good article. I wish it would also cover how to mitigate the corrosive effects on the aluminum. I have heard of people painting the inside of the bowls, with lacquer. but that does not help the passages.

    Luckily I can still find non-ethanol gas. It cost 40% more but is less headache.

    Same here, the champagne gas here has no ethanol in it but that could change like the wind in a day.
    Ya George it would be nice to protect the guts of our carburetors but as you mentioned, how do you protect the jets and tiny orifices and rubber accelerator pump and brass/copper floats inside? Paint would eventually flake off and cause problems years down the road. Ceramic coating would be good but not in the orifices.
    For all of you who have carburetors, it would be in your best interest to buy the premium fuel which usually has no alcohol in it. If you have a carburetor, avoid all fuels containing E10 and E86 or any ethanol or methanol in it. Read the labels on the pumps, they will tell you if they contain any ethanol or not. Higher octane fuel doesn't really cost all that much more plus it increases your fuel millage. My truck consumes less high octane fuel vs the cheap stuff. You get better power with high octane fuel also.

    Here, most states do not require E10 to be labeled as containing ethanol. Now they are trying to drop the mandatory labeling of E15.

    I read once about a method of anodizing a carb body, to help protect it, but cannot find it now.

    You'd have to coat the floats some how as well as they turn green when sitting for a while with any ethanol blended fuels. If anyone is running ethanol blended Fuel, you can run a bottle of water remover in your fuel with every other fill up to help mitigate driveability problems.

    I was under the impression that HEET and them like are predominantly alcohol, so adding it to ethanol fuel would be adding more of the problem to the problem.   Ethanol fuels already have water-absorbing properties.  Am I believing urban legend here?

    two different kinds of "treatments" heet and such are for water in fuel ice problems , the other is to keep the ethanol from damaging your new carbs like eddy's "carter" carbs . Lucas makes a green colored additive that seems to work .

    HEET and those products are typically iso-propyl alcohol and really only good for line freezing problems. They're a tiny bit more like gas (one extra carbon) than alcohol and probably combusts with water better than ethanol with water. Really only useful if you have excess water.

    I use Startron Star-brite. So far so good, hoping to get the cruddy gas burned up soon.

    Fuel additives fall under at least 2 categories. (A) Those that are for keeping gas "potent" for long period of time (storage). (B)Those that are for cleaning the fuel system. These should be driven somewhat promptly & the gas burned up.

    The convenience store (Sunoco) where I get my "recreational fuel" good gas also sells racing gasoline in 5 gallon buckets. I don't know the cost.

    These funnels are good at removing water in fuel. I would like to try one and love to try to use it at the gas station. Somehow stick it in the vehicle and pump the gas through the funnel as you fill your tank. I doubt it would work by you never know until you try! It would probably take forever to fill up. Lol

    Here's another video testing water removers. Apparently nothing actually works. I've heard you can add water to gasoline in a separate container and shake it up to mix the two and then let it sit for a bit to separate the ethanol from the gasoline as ethanol binds to water and then draining it out as water sits at the bottom but I've also heard that that technique lowers the octane levels in the fuel. I'm sure someone will find a way to line the inside of a carburetor and fuel pumps, cause it will eat an aluminum pump also - diaphragm and all.

    This is an interesting video, he talks about fuel storage and the damaging effects of today's fuels. Have a look.

    P.S  - I remember on a different thread someone mentioned race gas in a can (not that 93 octane is race gas, lol) but I didn't realize it came in the same style can as actual race gas does and available at any old gas station. That's cool! We don't have that here in Chinada. I wish we did. If i want race gas in a can like that i have to go to the speed shop parts store to get it.

    I found another valuable video for anyone who is experiencing carburetor driveability issues with their truck. This guy goes by the name ThunderHead289 and he is pretty sharp when it comes to carburetors. This is the guy that encouraged me to put a fuel regulator on my engine. In this video he explains fuel return back to the tank. Check it out, it's valuable information!

    I wonder about hard coat anodizing, such as AR15 receivers.  Problem is the aluminum isnt the only metal getting ruined.  Brass emulsion tubes seem especially vulnerable to corrosion based on my limited experience.

    That's a fact. Today's fuel not only affects the aluminum but as you said the brass floats are affected and so are rubber parts.

    From the flow of gasoline?  I'm talking the milspec treatment, not BMX bicycle stuff, which makes colors but not hardness.

    I'm not sure typical carb metals can even be anodized.

    Ya, I'm not sure also. It would have to be thin and durable. So many tiny orifices in a carb and brass jets etc....

    This is something I was super concerned about several years ago when E10 first hit the pumps.  All in all this is what I have to say based on my experience with several carb engines. 

    It will kill rubber lines, there are now rubber lines that can handle ethanol.  You should change over to them.  the rubber breaks down on the inside and fills the carb with a black ooze.

    It makes the steel lines rust inside if the fuel drains back to the tank.  This takes out fuel pumps and in a return system fills the tank with rust.  The OEM lines seem to handle it okayish, replacement steel lines are lower quality steel and don't.  I put a filter on the return line to keep from pumping rust back into the tank after a long sit and try to run a filter between the last steel line and the carb.  Unless you want to go to stainless lines (nice and hard to work with)  there's not much of a fix here.

    Dodges are blessed with a plastic tank so that hasn't been an issue yet.  The sending unit will be eventually though. 

    As for the Carb itself.   It seems like there's more concern but I'm not really seeing issues like were expected.  I recently did a carb that ethanol stabil in it for a year and it was an absolute disaster inside.  That is the first carb I've seen major issues with and based on the fact that I've seen numerous carbs without any treatment without issues I will not be running any stabilizing treatment in any of my vehicles.  In the ones with nothing it seems as though the fuel evaporates out before it does any real damage.  I'm more concerned with the fuel delivery system.  In small engines (sleds and quads) the needle and seat need a little massaging for just a touch more clearance than they used to.  The surface layer of corrosion will happen and it needs a little room for that.  Again it seems to stop after that initial surface layer forms.

    That's all I can think of at the moment and I'll likely get a little crap for saying it's not that big of a deal.

    Plastic tanks didn't appear until mid 70's. Us folk with older Dodge trucks (and cars) & in cab tanks have that area to worry about too.
