The front one is straight forward. The rear one is harder to access. You'll also need to clamp off the hose in the rear to prevent diesel fuel from flowing.
Kinda like a surgeon clamping off a bleeder.![]()
What sort of valve did you use?I install a valve in mine on the first change so it easy thereafter.
I use 2 hose clamps purchased at Sears for $15 a piece. No leaks at all during the filter swap.
