There certainly will be!
It's already been discussed on TM that some of the Plus 4 hose are tight and may rub on the hardware.
Here's one - tight against the alternator bracket. I've squeezed a rubber buffer in the gap for now but this needs a better hose for clearance:


This is where the T piece taps on the bukhead, easily fixed with a neoprene pad.


And here the heater hose passes over the bulkhead corner, again fixed with a neoprene pad.
