I wouldn't run nylon as a permanent gauge tube. Should the line ever split, there'd be high pressure diesel everywhere in no time. I run a gauge with hydraulic type of hose however I'm thinking of taking it off. Gauges are great when there's problems and you need to diagnose.
Over the years of running alternative diesel any problems have almost always come down to the same thing. Trying to run diesel that is too heavy and can't pass through the filter. Otherwise earlier on, I was trying to run diesel that was plugging the filter. Either way the problem was not enough diesel flow to the IP.
You'll see the effect of fuel starvation on the gauge, gyrating the needle with the IP desperately trying to get its' full quota of fuel.
The point is to keep the diesel thin so it will pass through the filter and clean so it doesn't plug the filter. Why it took so long for me to learn is a mystery. Sometimes you have to try stuff I suppose.!
A vacuum gauge measuring the effective restrictiveness of the filter element is equally handy for diagnosis.
Hope this helps.
