1845 Skid Loader

I was operating my 1845 skid loader yesterday when it started stalling out and quit. Let it sit and it would start but then stall back out. 188 diesel motor. I took the fuel line loose and blew back through it, Little hard at first then I heard it blowing back in the fuel tank. put it back together and it ran fine but I noticed after a bit it started sounding like it was getting plugged again so I suspect ive got some objects in my fuel tank. I can see where the fitting apparently screws...
