657X oil injection pump (small line) brass/metal nipple broke

[ezgoin92]

I removed the rotary valve cover to get to and clean the carbs. While putting everything back together I broke off the brass/metal nipple that goes from the pump to the small feeder line on mag side leading to the Mag cylinder. Is there a way to fix this

There is a check valve I believe in that fitting,,so you may have to buy another one,
