Hi Finn
 
    Glad you found the crack in the fuel line when you did.  Sure wish you would install proper fuel hose thought.  My aircraft would miss your aircraft {:>)

You just want me to spend more money that I don’t have :). All my fuel filters and fuel pumps are below tank level, so there is not much suction, but gravity fed. Have you seen Finn’s fuel lines? He is my hero.

I know you're kidding, but my polyurethane tubing has been holding up well. About 5 years.
However, I would not use them in a high-pressure fuel system (well, maybe I would...).
Also, I just found the source of my fuel pressure problem this last weekend. After a bit of a crosscountry I noticed an oilstreak along the left side of the airplane. Couldn't find an oil leak, but noticed a few drops under the airbox. Probed around a bit further and found that one of the fuel lines near the firewall had what looked like cracks in it.
Replaced the fuel line and fuel pressure back to normal at altitude. Best theory is that at sea level the surrounding pressure was enough to keep the hose intact, but at altitude it would start leaking enough to drop pressure.

Yes, yes, Ed. I know, you told me so.
