Joey Mack Posted April 9, 2023 Share Posted April 9, 2023 on the front of the engine by the over board breather is a 1/4" pipe plug. use a 1/4'' ratchet to remove it.. you can put shop air in that port at around 70 PSI. with the oil pan down, you can look up at the center lobes on the cam to see if fuel is coming out..

IGV Posted April 9, 2023 Author Share Posted April 9, 2023 Is that the plug you where talking about? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 9, 2023 Share Posted April 9, 2023 yes. You can remove the fuel line that comes from the tank to the primary fuel filter, pull the fitting out of the filter pad and plug the port, so you can maintain pressure.. I suggest using a pressure regulator and start at 50 PSI and check it. it may take a minute or 2 to see a leak.. dont go higher than 70 PSI.. Be cautious..

IGV Posted April 10, 2023 Author Share Posted April 10, 2023 Fjh the lift pump ? What I have noticed is that in the secondary fuel filter like metal shavings or metal filings? I don't know if im writing it right? Quote Link to comment Share on other sites More sharing options...
IGV Posted April 10, 2023 Author Share Posted April 10, 2023 Could the lift pump be bad? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 10, 2023 Share Posted April 10, 2023 Yes the lift pump can fail.. (Your unit is updated from the E-Tech series. those had a few issues).. when the pan is down, get familiar with the space between the front timing cover and the fuel pump..( its barely an inch of space) put your eyes on the drive gear as best you can.. spray brake clean up there to wash the engine oil off the gear and block.. let it dry or use shop air to dry it.. when you do the pressure test, if you see fuel dripping from that spot, its highly likely the fuel pump seal has failed, and the pump will need to be replaced.. its tricky, but you can pull the fuel pump away from the block a bit to let it drip out side the engine to check for a leak, because above the fuel pump gear is another 1/4'' pipe plug that is in the fuel gallery.. it is below the one you posted a picture of.. If it leaks (and it can) it will go directly into the crank case. if you have the fuel pump pulled back, (all lines and filter still installed) and pressure test the fuel gallery, and fuel is NOT dripping from the fuel pump but is running down the front of the block from the fuel pump area, then that little bastard plug is leaking.. Are you following me so far?? I am not trying to build a mountain with a molehills worth of dirt, but I have been here many times, and with the cost of firing a parts cannon nowadays, I make sure I test as much as I can... even if the labor is a bit much.. jojo 1 Quote Link to comment Share on other sites More sharing options...
IGV Posted April 10, 2023 Author Share Posted April 10, 2023 Ok I will follow all the steps and procedures you guys tell me, so for both test I only put pressure on the plug that is in the top ? Quote Link to comment Share on other sites More sharing options...

Oil dilution can be caused by this pump as well that is why the dilution test is important! Quote Link to comment Share on other sites More sharing options...

You are the lead in this thread and are teaching the right troubleshooting path here! 1 Quote Link to comment Share on other sites More sharing options...
IGV Posted April 10, 2023 Author Share Posted April 10, 2023 Yes fjh I hope I can troubleshoot the issue as soon as possible will check it tomorrow and see what happens thanks Quote Link to comment Share on other sites More sharing options...
