It’s highly likely I didn’t search enough I’m sure but I have 2 hoses to go including the PHH…of which I can’t even locate. Must I remove the throttle body or intake?

Any advice would be appreciated!

Thank you in advance.

EDIT: so it may jot be the PHH I still need to change but the two in the photo with the blue arrows bellow.

The two you have pointed out are by pass hoses. The longer, curved hose can be replaced with the TB in place but the short, straight one was such an SOB to access that I ended up removing the TB.

The PHH is off the head, above the starter back near the firewall. It’s the short green one in this screen shot from the pic you posted. Remove the front left tire to access the PHH. You might consider removing the the steel pipe that the PHH joins with the head and run a continuous length of gates 5/8” heater hose from the head up to the heater valve. It can be routed nicely along the passenger side of the brake booster. This eliminates something like 4 hose clamp connections. Many have done this. I did mine as describes above 5 or 6 years ago.

Did you do the same for the hoses on the other side of the heater valve, cutting the hose to size? I tried to order the rear heater bypass kit but it was on backorder.

I'm trying to decide if I should make my own bypass or just replace all the OEM heater hoses with the trident thing.

I chose not to delete mine and picked up the remaing 5/8” hoses from the dealer. It’s a Cali truck so there isn’t too much corrosion present.

Achievement unlocked!

I was able to replace the short one with the insulation by removing all the engine harness plugs, large vacuum breather hose, small 1/4” vacuum hose while sitting on top of the air filter.

On to the last one…
