Following consecutive draws against Buriram United and Chonburi, the Twin Qilins got their title bid back on track last weekend with a hard-fought 2-1 victory over Bangkok Glass.
And after watching second-placed Chonburi close the gap on them a day earlier after beating Buriram 4-2, Muangthong produced the perfect response by re-establishing their ten-point lead at the top of the table.
Brazilian striker Paulo Rangel opened the scoring for Slavisa Jokanovic's charges in the 14th minute but Wuachon posed plenty of resistance until 19 minutes from time, when Piyaphon Bantao finally got a second to wrap up the points for his side.
Relegation-threatened BBCU's problems worsened as they fell to a 2-0 defeat at Chiangrai United, who took the lead in the 25th minute courtesy of a Antonio Claudio strike.
Claudio's compatriot Leandro Assumpcao then doubled his side's tally in the 64th minute to condemn BBCU to their 12th defeat of the season.
Samut Songkhram moved six points clear of the relegation zone into 13th place after a convincing 4-0 rout of TOT.
Napat Thamrongsupakorn, who has been included in the Thailand squad to face Laos on Tuesday, gave his chances of earning a first cap no harm by scoring twice in the opening 15 minutes to give Songkhram a comfortable lead.
South Korean striker Park Jae-hyun then added a third in the 24th minute to all but kill off the game even before the break, but it took the hosts until the 88th minute to add a fourth when Bireme Diouf found the back of the net.
Finally, bottom side TTM Chiangmai played out a 0-0 draw with Esan United.
