They appear to be 1/8 pipe thread but I've tried several different fittings of different brands and none will thread properly. My next thought is to chase the threads with a tap, but before I do possibly irreparable damage to an expensive unit I wanted to see if there are other thoughts, opinions or concerns. Happy father's day to all you Dads! Thanks, Marcus 40286 hopefully installing the wings next weekend, the lights at the end of the tunnel!

I got the black fittings from Wicks and ACS for push-on tygon hose, and got 1/8" NPT on them. I wouldn't worry about chasing it with a tap, as long as you go slow and easy, and maybe only go a couple threads in to start. If it doesn't make it work, then I'd send the unit in and let them correct it. I don't know this, but I'd think that the ports would be a modular component anyway....but I've never seen the insides.

TDT do not archive ________________________________ Sent: Sat 6/17/2006 6:20 PM tube) --> RV10-List message posted by: "Marcus Cooper" Tim, Hopefully not too simplistic, but I just used the tubing that fit the insert and used the other tubing for the FAB drain line. I can't imagine using thinner wall for the drain line would impact anything. I didn't even notice the plans error. Marcus Do not archive -----Original Message----- [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Tim Lewis Sent: Saturday, June 17, 2006 5:42 PM tube) --> RV10-List message posted by: Tim Lewis Van's, Step 6 of RV-10 plans page FF4-2 calls for the use of 24" piece of PT-035x1/4 (thin wall tubing as used for FAB drain line) to be used as a fuel overflow tube for the engine driven fuel pump. As the name implies, PT-035x1/4 is 1/4" OD with .035 wall thickness, leaving an ID of .250-.070 =.180". RV-10 plans FF4-2, figure 4, calls out the use of an F63-PT3-25 insert to go inside the overflow tube. The F63-PT3-25 has an OD of about .137". The F63-PT3-25 is normally to be used in high pressure lines, such as the PT-062x1/4 RV-10 brake lines, which have 1/4" OD, .062" wall thickness, leaving an ID of .250-.124=.126". You can see this usage of the F63-PT3-25 on page 38-6, figure 2. If one tries to use the F63-PT3-25 with the specified PT-035x1/4 (thin wall) tubing, the F63-PT3-25 simply slides down the inside of the tube and falls out the other end. It's just too small. Once could use the F63-PT3-25 if one replaced the specified thin wall tubing with thick wall tubing such as left over brake line (PT-062x1/4). I'm hesitant to do that without checking with Vans, however, because the resulting ID is noticeably smaller than the specified tube. What approach do you recommend?
