Offroad-Express

have a leak coming from the cast steel back casing on my 1kz injector pump, it looks like i may be able to remove that specific part while pump is on the truck, was hoping someone on here has done something similar to tell me the do's and dont's before i go ahead and break something... thanks in advance

It sounds like the leak is in the distribution head thingy.
Don't think you can do it on the truck...
Before you start have a read thru this web page and look closely at the photo's.
It says Estima but its a 1KZTE pump tear down....
May help..
