guage air line question

Im running 1/4in air line to my 3 guages that I have, but I'm relocating them and I have the fittings for 1/8 plus I have like 200 feet of DOT 1/8 air line. What is the difference in using the 1/8 to using 1/4 if there is any? Thanks in advance

no difference, 1/8th is actually easier to plumb since its more flexible.

1/4" is a pain in the butt to route, especially if you're going to the a-pillar! 1/8" line is perfect- you won't notice any real difference in gauge response, so go with what you've already got!

yeah see my guages were mounted on the A pillar with 1/4, well im mounting them in the dash and I already have the line and fittings, so I guess ill run 1/8. Thanks guys
