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
Is the line supplied with the isolator for the gauge connection? Do you supply a line for the fuel feed side into the isolator? About 2-3 ft long with 1/8 or 1/4 AN filling? Thank you for your inquiry. The isolator comes as shown with the 4 foot braided line to go between isolator and gauge. The correct 3 foot line for the fuel side is 3227: https://www.autometer.com/4an-braided-stainless-line-kit-3ft.htmlDate published: 2019-12-31
What is the recommended autometer 100 psi fuel gauge that will connect with your isolator # 5282. I'am installing a Holley Sniper fuel injection system and want an in cabin fuel pressure gauge. Do you sell a kit? Thank you for your question. You can use any of our mechanical fuel pressure gauges. They will all be compatible with this unit.Date published: 2019-12-24

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
Can I purchase the isolator without the ss line and rest of kit?Thank you so much for contacting us. Unfortunately, we only offer the high pressure isolators with the line included. Sorry for the bad news.Date published: 2018-08-01
