Customer bought this truck not running with seized/bent valves. I did the cylinder head and now it is hard starting.
There was some tests that I didn’t film, one of which I should have, I put a barbed fitting on the suction line of the pump with a hose going into a jerry can of diesel and ran it off that (eliminates the fuel suction lines) it seemed to run well with that, hence putting in new suction lines.
