Everything for now is key on no start/wait ten minutes. Do not start the truck with the return blocked.

They do make that Echlin injector spider for your truck if it gets that far:

we already know the leak is in the intake Plenum so he’s almost certainly going in there anyhow. The question is is that the Regulator or the spider
