Hi everyone! I'm Juan from Argentina so I'm sorry if my english is not so good.
I have bought a Isuzu Pick Up 3.1 TD a few months ago and i have been repairing thing and changing filters, etc. My problem now is that after changed the gas oil filter i discovered that the hand pump, which is up the filter, doesn't work (or i believe so) because when i pump it nothing happens. After a while trying the gas oil never came up, neither the pump got hard, nothing.
So my question is, is there an another way to purge the filter and gas oil system? or any way to repair the hand pump?
