Removing mixing seal from Mitsubishi 4D32 Canter feed pump. 

They know what they do in short term they r expert

it's mix diesel to oil right? so oil level goes higher? I have canter 4D31 engine and oil level is getting higher. It's not coolant s it's have to be diesel. engine works great no smoke and start up easy.

What substitute can I use for the prime pump seal
