I did the old fashion way, I remove the tank then wash & rinse with gasoline for many times until the suspected suspended materials were removed.
Lastly, spray it with pressurized air with the tank upside-down.

Pero kailangan mo ng marunong mag-dismantle ng tangke at alalay. Or punta ka na lang sa kakilala mong shop at let them do the task.

Effective naman yung ginawa ko dun sa lumang Nissan ko, kalahating basong foreign materials yung naalis, buhangin, parang durog na shell...etc

ah ok... siguro ganun na lng din gagawin ko.. kala ko kasi may mga special compound pa na nilalagay don sa loob para maging malinis ulet... sabi kasi ng iba lagyan daw ng mga barya para magsilbing liha yun sa loob at alugin ng matagal .... di ba nag sspark yung barya kakaalog at haluan pa ng gas konte.. baka magliyab?

pwede rin muriatic acid mas effective bumakbak ng mga kalawang at dumi sa loob ng gas tank, then banlawan mo lang ng maige ng water tapos bugahan mo ng pressurized air (using an air compressor), tapos patuyuin mo for days (yun nga lang mga 2 days mong hindi muna magagamit kotse mo)

Pag obvious na nonsense,wag na naniniwala sa sabi-sabi.

Meron kasing speacial paint/coating ang loob ng tangke para hindi mag-corrode, kaya kung ano-anong chemicals o compound ang panglilinis mo baka masira yun.

Kung nababakbak na yung coating na masisilip mo nman pag natanggal na yung tangke, I suggest pilitin mo lang alisin through rinsing o konting sundot. Hindi naman kailangang crystal clear ang pagkakalinis, importante yung mga buha-buhangin lang.

Last option na yung bubutasan yung tangke para malinis na mabuti o matanggal kung may malaking materials na hindi maalis. Problema pa rin dito ang corrosion later on plus risky na rin yung solidity ng tanke kahit na mahinang pa ng maayos.

Lastly, pag back online na ang tangke, 1/4 pa lang e refuel na agad. Huwag ng pababain pa dun para hindi na pumasok sa linya kung sakali mang hindi natangal lahat yung dumi.

ah ok mga masters, maraming salamat sa mga bright ideas nyo po... linisin ko na lng na parang naglinis ng balde.. tanggalin ko na lng yung parang putik2x don sa loob.. meju nabaha ata to nabili ko eh.. inabot yung tangke...

anyways.. maraming salamat... ride safe

Are you using a fuel filter? If so, any dirt should not be able to go through. It will clog up the filter but no dirt should be able to make it to the carb.

thank you

if a brand new tank (or surplus and in very good condition) is available and affordable, then i would recommend tank replacement.
a problem with your old tank, is that it may spring a leak in the foreseeable future, partly because the rust you removed has thinned out the remaining metal...
i am told, filling up your tank with nitrogen gas, you can sort of sandblast the inner surface by putting in metal bearings and shaking it ..
