Ford Transit Connet

Good afternoon I wanted if you could help me with a problem that I have had with a gas-oil filter of a Transit Connet changed it and after using several times in the afternoon in the morning following Arranqua and I stop and I have no longer been able to start it either with other filters or theirs that it carried. What can happen? .THANK YOU

First of all check all the joints that you have touched when you changed the filter (cracked toricas) and also the jasoil input and outlet sleeves of the filter for some air input.

It could be that there is air in the oil line.
