The parts diagram says different. I’ve worked a quite a few of thes, only tractor dealer anywhere near me was a Branson. Now TYM and LS.The feed pump is mechanical not electric on this engine.
I did replace fuel line between the filter and and pump and also pulled line from feed pump to main pump to check flow. It seemed to pump decent volume and covering end of hose with thumb it would spray some so could be 3 - 5 PSI. Had air is system so started hard but will let sit and cool off to try it again later.
