Sometimes the line that comes in those kits falls right in the area of one length is barely too short and the next one is two feet too long.
I like making my own hose from -4 Teflon lined hose and just put my own ends on. Then the hose is the length.
Of course, if you are one of those guys who can reach into a basket of buttholes and pull out a rose, you'll get lucky and find a prefabbed kit the correct length. I never get that lucky. I reach in and get a handful poo.
BTW, I've seen way to many electric gauges that have a plus/minus accuracy that you'd be just as accurate with just a light.
And, I prefer the -4 hose size over the -3 stuff out there. The gauge is more sensitive with the bigger diameter hose.
