Default So, you think ya got em all?

I was in the shop today and decided to set fuel pressure at the regulator and test the fuel system for the first time, made up transfer lines and a ground wire for the 5 gallon gas can, (wings off) and discovered port plumbing was reversed at the duplex valve, so I crawl under to switch the lines and discover one of the fuel line was loose! After years of hearing of this and told myself over and over to check every B nut during the build, and I did over and over, I still had a loose fuel line! I guess I am human and will make mistakes, still cant believe this........could have been real bad.......

That's why it is so important to have as many experienced sets of eyes look at your Procter as it finishes up. I never dependend on myself or the inspector alone!

Others always find errors I miss.

also check the plug on the top of the gascolator. I found mine leaking after a couple of early flights. It wasn't tightened.

Every experienced builder that walks through your hangar should have access to a wrench and a roll of blue tape. Check anything you want and tape anything you don't like. I once left a buddy's engine compartment looking like a blue tape confetti bomb went off in it....you can't have too many eyes on.

Default Nice Catch

I performed the initial flight on an RV a long time ago (not mine) that had the left tank plumbed to OFF, meaning when the pointer was in the LEFT position, the fuel was actually OFF. Only my 30 second full power runup prior to takeoff prevented me from having some unplanned excitement, or worse, as the engine quit on the ground.

It is true that we're all human. We just need to know it. I feel so fortunate to have an "experienced builder" built in. She always knows when I've messed with the airplane and I leave things open so she can check my work when I'm not around.

Other things that we do when working together (often) is each person does different "phases" of the job with a final cross check.

It isn't just construction, it is maintenance as well. I completed the FWF portion of my condition inspection yesterday and managed to bungle the timing process on the PMag once, and when I corrected it and buttoned up everything, I realized I had to de-cowl again to reattach the MP line. It was like a Three Stooges episode...

And hot.

Same here! Ann will not allow me to "re-cowl" the airplane even after an oil change until she has inspected and OK'ed.

Default Highly recommend an air leak test before using any fuel.

Having inspections is good, but realize you can test the system for leaks alone and it will tell you if it leaks. I blocked the system at the fuel pump exit, and at one wing root. Then added 30 psi to the other wing. Locked the valve and the gage dropped. I found the leak, repaired, and left it overnight. NO drop overnight.

Both my 10-friend and I found leaks like this. It is easy and will always find a leak.

That's a good idea, but I have a slightly more complex fuel system, supply and return both tanks, but that's a good idea! got a steady stream of return fuel @ 35 PSI both tanks.....@ tank supply and return. All high pressure is on firewall side.
