I think you will find that most folks step on the brakes and fix what leaksAce said:I see nowhere in the plans to test the brake and/or fuel lines for leaks. Is anybody doing this? If so, what method are you using? vacuum? pressure ? thanks ,

Before buttoning up the fuel and brake lines with covers, hoses and the forward fuselage , I wanted to check my entire system for leaks. I am less worried about the hoses as they were tested by the supplier, http://www.aircraftspecialty.com/
I am much more concerned about the fittings connecting them all together.
I have 2 electric fuel pumps, fuel filters and a duplex Andair fuel valve. Is it advisable to pressure test this as a system (not the tanks) from wing root to firewall. The working pressure will be 35 PSI.
If I do pressure test them, what is considered acceptable? An obvious leak is easily recognizable. What pressure should I test it to? How long should it be tested for and what, if any is an acceptable pressure loss over x hours.
Is the Andair fuel valve able to be pressure tested? I just sent them an email.
Thank you.

Hello,
Andair got back to me and stated the fuel vales are pressure tested to 80 PSI. They can perform higher pressure testing but they would do that at the factory.
Pressure testing is going well. I set the pressure yesterday afternoon at 30 PSI. As of 11:30 AM today the PSI has dropped to 15 PSI. No soup bubbles detected but I will apply again today. Not happy about the drop, but wondering if this is acceptable? Probably not. The volume is so little that even just the expansion of the lines due to the pressure may have an impact on the pressure.
I am going to run some 100LL fuel through it and check the pumps, pressure regulator, check for leaks and also do a preliminary fuel flow. This will also clean out the lines.
