I agree with Rick, an isolator is a big no-no! Just get a nylon tubing kit for an oil pressure gauge and use permatex #2... Mine has been like that for a year and I have had ZERO leaks!

 

I don't really like running a fuel line into my cab but I've heard of way more problems with the isolator's so I just have a nylon line running to my guage with a ball valve on the filter housing so I can turn it off if it ever starts to leak. I made my own gauge mount molded into my ash tray mount and I really like it but I need to take it back apart to paint it the right color.

 

Seems to me that if a person was handy with a fuel line cover tube, some rubber, and glue he could make a nice leak-proof return line for any leaks that could occur at the fitting. If it leaks, the outer tube returns the leak back outside the firewall....maybe even to a clear container you could check to see if you do have leaks.

 

Sorry to be the bearer off bad news to the "fuel in cab crew", but it is illegal to run a fuel line into your cab in most, if not all states. Not a huge issue on the law alone, but good luck trying to explain it to your insurance company should you have a fire!

 

Just put a shut off valve in the engine compartment. If you have a leak...shut it off. And yes, it is illegal to run a fuel line in the cab, but so is boosting to 20 psi and smokin the tires at a stoplight...drag racing rice burners on the streets...annoying the neighbors with straight pipes...jaywalking..............

 

Hink - You are missing the point..........oh well, survival of the fittest!

 

While I would never consider running a GASOLINE fuel line into the cab, diesel fuel is MUCH harder to light off.
I use high quality stainless braided teflon line, grommets where lines pass though bulkheads, and quality AN and NPT fittings.
I have no problem whatsoever with hauling my wife and grandkids in my truck.


Different Strokes..........

 

I agree with Shovelhead 100%.

 

Nylon tubing will crack and leak eventually. It gets brittle. It happened to me.

Nay on the isolator. Just plumb it direct with good lines and you'll be fine.

I really good option of FP guage plumbing is 1/4" push-lok type hose.

Thanks for the opinions. Where is the best place to tie the fuel line in under the hood? Directly at the VP, the fuel filter housing, in between the filter and the VP or what? Pics or description would be great. I plan to install a Glacier or similar system in the near future, does the location of the fuel pressure line tap need to be in a certain spot for it to read after the Glacier Pump? I am new to this and the VP thing bothers me, so I want to make sure I am monitoring everything correctly.

Thanks Again,

 

I get my pressure reading at the outlet of the fuel filter. That way I can tell if a dirty filter is bringing the fuel pressure down, and it'll tell me the actual pressure going to the VP44. On a stock system, the easiest way is to get a tapped banjo bolt and run the gauge line from there. Glacier's big line kit has a "T" to attach the line to. Vulcan also makes a nice kit that uses the stock LP, but moves it to the frame by the tank. It also uses larger fuel lines all the way to the VP44. This is the kit I'll go with when my LP dies. It's a good bit cheaper than Glacier too.

I found a copper tube kit at NAPA, very small diameter, so no needle valave was needed. Seems like lots of complaints about the isolators, few if any issues running into the cab.

 

Sure am glad our trucks dont run on skunk juice

 

Agreed here

my gf (if i have one at the time), mom, dad, grandparents, and passengers dont have a problem riding in my cab, and they know that my fuel pressure is direct... I also run high dollar lines, i dont skimp on that...

for gods sake do the plastic tubing if you run a braided line the rattle will drive you insanevery very annoying on a long drive...but i just used braided line into the cab works lika a charm alot less plumbing then with a isolater...............and if you get in a wreak every good fire fighter should check the pillar under the plastic b-4 he cuts
