FUEL PRESSURE ISOLATOR KIT, FOR 100 PSI GAUGES, BRASS, INCL. 4FT. #4 BRAIDED STAINLESS LINE is rated out of 5 by 2.Rated 5 out of 5 by Chad H from Tough setup Getting the system to work properly was a little tricky at first. I had to completely start from scratch with the fluid to get all of the air out of the system, but once that is done, it's great. It's nice to have a fuel pressure gauge in the cab of my off-road vehicleDate published: 2018-12-08Rated 4 out of 5 by Mort from Works well in most applications Line is too short for some applications so I wish there were options for longer lines. Adding antifreeze to the longer line and getting the air out was a pain. However, in the end it works great.Date published: 2018-03-07

Can this kit be used to isolate a mechanical oil pressure gauge, such as the type found in classic Chevrolet trucks?Hi Mike, thank you for the question. This isolator is designed specifically for fuel and we have no official experience with how it would function with oil. In theory it seems like it should, but not something we can recommend.Date published: 2019-03-26
