JD 1520 Fuel Leak

[Lakeside57]

Have a JD 1520 diesel that has an early style(obsolete)Roosa Master injection pump. It has a steady leak when engine running at supply banjo fitting on bottom of pump. Have replaced the hollow screw and two washers. Still leaks. Not spewing, but a steady drip. Banjo fitting does not appear to be cracked. Have tightened down as much as possible with no luck. Anyone have a suggestion or is it just a trashed inj pump. Thanks

Replace the 2 steel washers with copper washers , the copper being softer conforms to the irregularitys better than steel.

Thanks Partspring. I just happen to work for a Ford dealer and we are also a Cummins dealer. We had copper washers in Cummins just the right size. I'm gonna try the out this weekend. Thanks for the tip. Great support and good people here.

Also spray line and mounting area on pump clean with brake/carb cleaner
