Well let's just say, I have treated the inside of my gas tank for rust and have it looking pretty good so i ordered new OEM standard carb and was wondering if I could replace S-shaped fuel line with a straight one from local auto parts store so I could use in-line filter to catch any rust b4 getting into NEW CARB and causing problems??

Hello,
Unfortunately you can't do that... Running the straight line will cause it to kink after a bit.... I have no idea why Honda made the petcock so that you had to buy the S line(MONEY) ..... That sounds very smart to run a fuel filter in that line...... You may be able to "rig it up" I was able to use a lot of zip ties and kinda make it work IT WILL NOT BE A LONG TERM FIX...The line will eventually kink up and you are going to end up buying the S fuel line anyways.... I like your idea of running a fuel filter though... Best of luck

I have a 2000 honda 350. When mine stopped working I disconnected the fuel line and saw the gas flow was slow. So I removed the tank and the tank selector valve.The tank valve has a strainer inside the tank. My strainer was broken and crumbling. Also the tank had dirt gunk in the bottom. So my tank valve had gotten clogged. The crumbling strainer bits could also clog the float valve, or stick it open.I found that the tank valve flowed OK on the RES setting. So after cleaning it up I put it back on (without the strainer) and added an in-line strainer. Then I made the mistake of replacing the fuel line with one I ordered from amazon.

Turns out the SAE30R6 fuel line is not ethanol resistant, and turns the gas orange, and eventually starts breaking down. This sends little bits of rubber into the float valve which clogs it open (again!).

So I went to autozone and got some more fuel line, and guess what? It also turned the gas orange. So I found the original fuel line and put it back on, even though it was a little stiff, and now the fuel looks normal.

I am still in shock that they are selling fuel line to this day that is not ethanol resistant.

It's crazy the crap some people get away with... Why wouldn't you make it Ethanol resistant????!!! It makes no sense!!

You can try... I'm not going to guarantee anything though... Why are you so worried about the rust??? Have you cleaned it out??? You should be fine....

I done the vinegar/baking soda treatment..got 99.9% the rust out and used pre-mix to coat it and then filled with non-ethanol gas..but I want to keep as much leftover rust that may b floating around inside from getting into brand new carb and clogging it up..carb work down this way runs around 85$, and im no good with carb rebuilds.lol..so I bought new one for 90$..don't want to b in same boat as was with old carb..lol

Ethanol breaks down non-coated rubber. SAE30R6 specs say it should be resistant to 10% ethanol, but it is not always compliant.
Premium fuel line can be rated to handle pure ethanol, but it is VERY expensive. Nylon fuel line may be resistant, but it requires a special tool ($100) to attach connectors.

In the picture:
regular gas on the left (hard to see), fuel hose soaked gas on the right (orange with black particles)
top hose from autozone, bottom hose from amazon

i guess i have to check what i put on last. it was from auto zone, local store. the special tool for nylon line, is it anything like a pex pipe tool? they squeeze a band tight, but pex line is stronger than most gas line, and bigger round., not so flexible as gas line. also, if both lines, turn gas orange, AZ and amazon, AZ not as much, can i only get fuel line from japan? not just for my atv, but for any gas line, that is ethanol resistant.

Bambreeze: If you want rot resistant line, if you can get a line that has a (teflon) lining in it. that will not break down, or call around and see if you can find a company like Earls Performance Plumbing for instance that will make you a line based on your original one. :D

Found this one at local parts store..gonna put in-line filter in and give it a shot for a couple of tank fulls then go back with OEM s-line
If you want to you can put a clear inline fuel filter like this on your machine to make it easier to adjust valves.

The video below is what I'm talking about.

Gates Safety Stripe II fuel line is supposed to handle up to 15% ethanol, and some local parts stores carry this. It has PVC added to the rubber, but I would like to see someone soak test it.

Gates Barricade fuel line has a thermoplastic liner, is SAEJ30R14 compliant, can handle pure ethanol, and is available on ebay. I believe this should work well, but soak testing is only valid if not done on the outside of the hose (gas inside of hose only).

I do not have a nylon line tool. I tried to improvise my own when I was repairing an old pickup fuel line, and it did not work. I ended up using Gates Safety Stripe II, but it was before the fuel filter, so that should block any rubber bits.

If anyone knows a fuel line is resistant to ethanol, please let me know.

If you have a filter like I do after the petcock replace it every 4 months or so to be safe but at a minimum replace it (before winter) at least.

I have a small engine repair shop. I use a part straight from mu shelf. It is an in line fuel filter that has the nipples @90 degrees not straight thru like most. This allows the use of 2 short pieces of fuel hose instead of the special hose you mentioned. The part number is 10423 from "Rotary" Look it up on line and buy 2! LOL

Thanks Team..got new line/filter applied and let it run out half
tank idling b4 removing tank and sloshing gas vigorously around inside of all areas and then running other half tank letting it filter through and to my surprise. ..it was clean looking..so I ordered new petcock and s-line..figured that would do the trick now without fear of carb stopping up..Thanks again fellows for 1 more save.. :)
