Fuel Pressure Issue?

I do like the idea of the valve to shut off the supply. I think I will skip snubber all together. Now I need to just buy a 1/4 npt needle valve straight through. I completely forgot that the fittings on the isolator are 1/4 npt and I can just remove those and put them in the new needle valve.

 

This is basically what I need but there has to be a cheaper solution to this than $60!

NAPA - PN# WH6820 roughly $8.00 for a the needle valve in the picture. NAPA also sell all the 1/8" NPT brass fitting too for fair price.

 

I need a double female 1/4 NPT. My plan is to remove the isolator completely and remove the 1/4 NPT fittings that are attached to it that connect the fuel hose and the gauge. So one side I can screw on the needle valve and then I can take on the quick dissconnect compression fitting vulcan includes in their kit and screw it in the needle valve and then re connect the 1/8" tubing. Should be a quick fix. I will call Napa since they deliver to my work lol.

Well I installed a needle valve inline and removed the isolator. All I can say is the isolator I got must have been a piece of ****. I fired the truck up and instantly 18psi again! Thanks for the help guys. I am happy with that instead of 3.5-5psi I was showing...

Most isolators behave this way. Just really rare to see a working last for very long either.
