Really hard to burst Air Brake Line rated for 600-800 PSI... I seriously doubt anything will happen.

 

Where did you tap in with the banjo bolt.

 

Right here at the fuel filter... No longer using nylon so disregard the nylon tubing.


I want to re-do this hook up and get back under the stock filter housing again. Because the stock filter acts like a water hammer suppressor.

 

Doesn't look familiar. Must be different setup. I'm 2001.5.

 

OK but is it rated for fuel ? Don't actually have to burst it, somthing could rub through it.
I think I don't want a pressurized fuel line in my cab, but thats just me.

 

I realize that the banjo bolt is cummins specific, but are the fittings and needle valve, etc. automotive specific or more like Home Depot/lowes variety? I see Geno's has a banjo bolt that fits into the schrader valve so that the schrader valve is still viable for pressure testing. Looks like a good place to tap in.

Not ready to scrap the isolator yet, but the gauge is now not reading any pressure at all. Runs fine, so I doubt it's accurate.

 

Everything in the picture plumbing wise is a NAPA part store thing.

The banjo bolt is from...

Late,but may help someone as I just did this myself.

You can use a funnel with different sizes hoses to fit the 1/8 plastic line. Loosen the bottom where the line goes into the isolator and pour the anti-freeze into the funnel from the top. The line will fill with anti-freeze top to bottom, and no air. Close line to isolator (bottom) when finished. A second person as a helper will keep you from spilling anti freeze.

If you still have an inch or so of air in the top of the tubing's line, use the syringe. Fill the syringe maybe 1/3 anti freeze(push out air) and use the syringe as a suction device. Get a tight seal on the tubing and use the suction to move the fluid from the tubing into the body of the syringe. Once you have all anti freeze fluid in the tubing, push anti freeze fluid back into the tubing with the syringe. Works like a charm.
