Any suggestions? Are they really "necessary"? I have no drains, and the vents are all aluminum terminating inside the top of the header tank which is a little oversize. If I put in three gallons, the tank still has plenty of room for the vent "T' to be in free air. The header tank cap is vented as would be expected. The system has worked well.
I am putting in the Piper fuel valve to replace the original weatherhead, and found NASCAR approved aeroquip fuel hose that is super lightweight with a Nomex/Kevlar braid that accepts standard AN fittings. Tygothane (or whatever it was) and nylon fittings may be light, but I prefer a few more ounces of safety.
FYI, I do park me EZ in the hangar in a level flight attitude using a weight in the front seat and a brace under the prop flange to balance the aircraft. I previously did not have a gascolator, but am installing one now with the other upgrades.
My aircraft was built well and very light ... I can afford the few extra ounces (Lbs) I may gain through the refurb... Removing all the heavy instruments and radio and going lightweight digital. Also going dual electronic ignition and scrapping the mags too. The new Lithium-ion batteries are lighter than the old marginal battery. I hope to add almost nothing to the original empty weight while upgrading capability and safety.
