Im looking at this gauge for my 01 3500. Just wondering if anyone else may have it or have any knowledge about this setup. Also is there any reason I couldnt remove the isolator if I have problems with it and just install a needle valve?
Seller recommends a "snubber" currently @ $15 + shipping and "oversize Banjo bolt" currently @ $13 + shipping. Do I need all of this??

Thanks!

I paid $50 for a new Isspro EV 0-30 psi gauge & isolator to a members' classified ad here, and sold the isolator on the classifieds for $25.
My fuel pressure with the FASSII is about 18.5 at idle, so a 0-15psi gauge would not work.
My gauge is plumbed directly into the fuel line with a needle valve as an emergency shutoff / pulse dampner. I have no needle vibrations, and I use 300psi rated hydraulic hose from NAPA for the line.
