Ok guys i need to change out the clear cheap hose that came with the boost gauge for something more reliable. any suggestion? What is this polyon?

ive never had a real provlem with the clear line for a boost gauge although ive had it leak at the fittings on oil pressure, the only real alternative i know of is braided steel line 1/8in. but youll have to swap out all the fittings on the manifold and gauge with a/n fittings like earls or aeroquip and this is not cheap!!! maybe somebody else has a more economical solution

Get a chunk of 1/8 Air Line (Polyon) from NAPA for cheap... It rated to 200 PSI typically extremely flexible... I bought 10 feet and 2 ferules for $6 bucks...

Thats the same stuff I am running for boost. I need to get my DP switched over one of these days.

I didn't know Napa sold that line, but now I do if I ever need it!!
