Pipes that have high-pressure combustible fluids inside them are at risk of hydrolock due to the linear pressure exerted by the inside pressure cause by combustion. Oppressive fuel-pressures (less than 25 psi) exist in diesel fuel systems because of their internal pressure. Diesel fuels with carbon levels below 10% pose less risk of hydrolock than fuels with carbon levels above 10% that have pressures of greater than 1.3 psi.

Frequently Asked Question
Can you use Teflon tape on diesel fuel lines?
No, Teflon tape is not recommended for use on diesel fuel lines.
Is silicone sealant resistant to diesel?
Yes, it is.
Can you use regular Teflon tape on gas lines?
No. Regular Teflon tape is not rated for gas lines.
Is permatex diesel fuel resistant?
Yes, it is.
What kind of Teflon tape do you use for a gas line?
I use the blue tape that is used for plumbing. It is a little thicker than the yellow tape that is used for electrical work.
Conclusion
Quick Stop Service Valves
Gas compressors tend to leak at screw tops and threads. A practical solution is to install quick stop service valves on top of the compressor tank before and after sealing the opening. QSP valves are designed with a release head that disengages automatically when a pressure of 250 psi lbs is released. The valve opens with pressure release and closes automatically when the pressure on the other side increases.
