I was wondering how someone is supposed to clean out their resin/plastic type gas tank off of an Earthquake tiller. I am doing some small repairs on it for a relative. The fuel lines completely deteriorated which seems to be a common problem people are having with Earthquake tillers. Old gas and the fuel line material is reall stuck and caked onto the bottom of the gas tank. I put 2 inches of premium gas in it and let it sit for 1.5 days but that didn’t really do anything. Does anyone having any ideas that would work for me to remove the gunk?

Use some white vinegar and a handful of gravel, or nuts and bolts and shake the tank vigorously ..probably going to take a few attempts...rinse out with HOT water ..then blow air into it to completely dry it out

I've used some of this carb. cleaner by removing the fuel tank and removing the fuel line fitting and plugging it and pouring some of the carb. cleaner in and doing exactly what Mark said and put in some nuts and bolts or gravel like what's used in fish tanks and going out daily and vigorously shaking and rolling the tank around for a few days and drain the tank and flush it out with hot water or maybe some fresh gas. https://www.autozone.com/fuel-and-e...VKxXUAR0n-wQrEAQYAiABEgLGxvD_BwE&gclsrc=aw.ds

My last barn find had nasty yellow/orange grunge in the tank. I took it off and sprayed it with purple degreaser and pressure washed it at the carwash.

Brake cleaner also works like a charm... but you have to do some scrubbing!

I think that brake and carb cleaners would break down the resin......same with acetone, which is great for getting that kind of stuff off of metal or glass surfaces....but can be nasty

Well, I’ve cleaned it a couple times with vinegar and some bolts/nuts. Now though a small amount of residue from the bolts as well as specks of the old sticky fuel lines cover the interior of the gas tank. I finished getting out the majority of the fuel line residue but now the tank looks like this. Soapy water didn’t get these specks out nor did gasoline. I did accomplish the goal of getting 90 percent of the large sticky sedimentation of fuel lines out of the bottom of the tank but now I have this new problem. What should I do?

Did you use rusty hardware?...Try using gravel and either vinegar or really hot water

Yeah it was a bit rusty, but that’s that darn sticky fuel line bits in there in addition to the rust. I’ll try the sand/gravel. thanks

No sand ...you need course stuff
