Another option appears to be available
	
	
		Hello all
Just joined up yesterday as I am researching buying a Discovery 4 (hopefully a 2015 SDV6) and have found so much of the info here incredibly useful.
One thing I have come across in my other research is a Spanish company that makes another emergency air up kit called Fastkit Faskit Info - Partsrover
To my newbie eyes it appears to meet the needs of this discussion and of interest appears to be working well with a 150psi portable compressor.
Interested to hear what more experienced heads think?
