I am having some difficulty with my John Deere 5020. It starts up fine and runs very well under a certain number of RPMS however whenever i get over 1k-2k RPMs after a while. It begins to rev down almost like it is choking down and then it eventually quits. It doesn't get started very often and i am thinking it could be algae in the fuel filter or fuel lines/injectors due to the old diesel. My question is should i clean replace the fuel filter and try to flush out the main fuel lines/injectors or could this be a bigger issue?
P.S. It has Roosa Master 687 fuel pump i believe so do i not have to prime/bleed the fuel system because have seen post of it being an auto bleeding system.
Really hope i get a response from someone, i am a college kid who inherited the 5020 from my grandfather and im trying to figure out everything i can about it to keep his legacy alive so someday i hope to restore. it.
