Great video, this answered a BUNCH of the questions i had about how to do this. The big picture finally snapped into focus

WOW! 3126 with Mechanical fueling system, finding any info on this engine is like finding a herd of Unicorns! I have a friend that just lost one in his boat and I'm just looking to learn about it. Not much out there that even admits to this engine ever existing!

[@BOPotstill]

pretty much the same fuel system as a 3116 MUI fuel system, some of the 3126 were MUI, most were HEUI

Thank you! This is a great help in understanding the 3126. It's what I'm driving on the new job.

[@garykay7418]

should the engine be cold or hot/warm when the rack adjustment is performed? does it matter? thank you.

[@johnpaulregalado1049]

Thank you for this video! When will you post a video for maximum fuel setting adjustment?

[@gordon3126]

Yes make a video of that setting please and thx 👍

Can simply get 6 gauge blocks and the fuel position on all 6 injectors that way ? I’m trying to save time and eliminate errors. Just a thought

[@markhussey3135]

I was gonna ask that same question

[@slowpoke96Z28]

I thought 3126s were HEUI engines?

[@zache4563]

slowpoke96z28 3126b’s and c7’s are heui. The older 3126 and 3116s have mui
