I have a 2012 DF70 with a bad fuel pump. I have removed all bolts and nuts on the outside face of the manifold but it is still connected somewhere, maybe a bolt or nut on the inside face.... I haven't located any instructions or videos indicating any additional bolts to be removed other than the outside facing portion. It is still tight to the engine at the front of the engine but is free at the back portion. Has anyone run into this issue removing the manifold or have a resource or instruction for this specific engine? I was going to have the shop replace the fuel pump but the quote was $1,300.00 so here I am. Any assistance would be appreciated. TY
