Alright here is the deal. First its a 91.5, shaved fuel pin, fuel screw in around a turn and a half, stock lift pump, stock injectors, truck has 275k miles.
My IP has developed a couple leaks at the same time. One at the feed line on top of the injector pump and one looks like its on the side against the block at the plate opposite of the ksb. Ive seen some discussions about IP case pressure with stock injectors and the fuel turned up but cant find any good info.
My question is, could it just be luck of the draw that I developed both leaks at the same time or could pressure have something to do with it? I just dont want to pull the pump and seal it and put it back on to have the problem again.
IP developed a few leaks, a few questions

It's not the pressure... turning up the pump doesn't change the case pressure.
The stock seals aren't rated for today's diesel.. and eventually they fail.
