I would install a needle valve instead. Isolators don't attenuate the pulses enough to save your sending unit. Regardless both units go between your tapped banjo bolt and your sending unit. You want to be as close to the IP as possible.

Toss your truck details into your signature liine please.

Beat me to the punch... But the only information you left out is you can get that needle valve at NAPA for about $8 bucks... :thumbsup:

I think this is trick.



Then all you need is the hose, and then the other end.

i actually used fitting that had 1/2 pushlock on both sides and a 1/8 tap in the middle worked really nice

I went through two of those and decided never to use another one. Running the exact same setup as Mopar1973Man.
