Plugging leaks in your avenger.
The hose that runs from the injector pump to the injector assembly and the bypass hose that runs from one injector to the other are often leakers. These hoses often crack from age and high temperature.
If either hose leaks on your Avenger, don't replace it with the hose listed for Items 31 and 35 in Fig 12 in TM 9-1440-433-24P (Sep 98). AMCOM has come up with a more durable hose that you can order with spec data SAE 30R7 3/16 inch and part number 2230-0187 from Abbott Rubber Co at (800) 852-1855. Or you can get the hose at your local auto supply. You will need an 18-in hose for Item 31 and a 6-in hose for Item 35. The new hose will be added to the TM 9-1440-433-24P.
The Avenger often leaks where the oil pan plug screws into the engine oil pan. That's usually because the plug gasket wasn't changed when the oil was changed. The gasket cracks or tears and the plug starts to leak. Whenever you change oil, change the gasket, NSN 5330-01-101-8076. It's also a good idea to change the oil filter when you change the oil to keep the oil clean longer. Changing the gasket and filter are being added to the steps on changing engine oil in Para 19-43 in TM 9-1440-433-24-2.
If a new gasket doesn't cure a leaking oil pan plug, the oil pan's threads have probably been stripped by the plug being cross-threaded.
