Good tip on the Sta-bil, thanks. We're lucky, perhaps because of the aircraft industry here in Wichita, we've not been subject to the ethanol swindle yet. Water in fuel, or the fear of it, can still be handled by a 99 cent bottle of gas line drier.

The Iron Law states that in all cases, the second type of person will always gain control of the organization, and will always write the rules under which the organization functions. ________________________________ Message 8 _____________________________________ Time: 12:13:17 PM PST US Subject: Kolb-List: Gas and PVC From: "Kirby, Dennis CTR USAF AFMC MDA/AL" (NOTE - Subject Line changed to reflect current topic.)

Anyone know how gasoline affects pvc? >> Grant - Following the advice of someone else on this List, I made a homemade gascolator using PVC. As you correctly observe - simple, cheap, effective! (I'd like to give credit to whoever it was that I copied it from, but I forgot who it was! Was it you, Richard P?) I used a 2-inch long piece of 1-1/4" diameter schedule-80 PVC, with end caps glued on. Drilled two 3/8" holes opposite each other near the top (thru the end cap), and screwed a brass fuel barb into each hole. On the bottom PVC cap, I drilled another hole in the center, and threaded into it a Curtis drain valve. I installed the gascolator so that the drain valve pokes out thru the fabric, on the belly of my Kolb. (Which also happens to be the lowest part of my fuel system.) Easy to take a fuel sample from on preflight. I used fuel-proof thread sealer goop (a Permatex product) on the 3 holes where brass hardware is threaded in. It's been installed for over 3 years now, and I've never had a leak. More details are in the archives - this thread has been discussed before. To answer the question of gasoline vs. PVC - before making this homemade gascolator, I set out to prove to myself that PVC would not be affected by gasoline. I filled a glass jar with gas, and dropped in a short piece of PVC pipe. I let it sit for several months. No discernable degradation to the PVC.

Where are you going to stop? All this fuss a few weeks ago about fitting an extra fuel pump. What for? Pat >> Pat - I am one of those whom you speak of who gets all hung up! In 1992, I was forced to make an emergency off-airport landing in my Tri-Pacer because of vapor lock in the fuel line. I was trying to climb over a mountain range in the middle of a hot summer in Arizona, and things got so hot in the engine area that bubbles began to form in the fuel line, causing the engine RPM to begin surging up and down (mostly down). The Tri-Pacer has no fuel pump - it relies on gravity feed from the wing tanks. I firmly believe that, had a fuel pump of any kind been installed, that Lycoming engine would have kept running. So now, I'm making up for it by having TWO fuel pumps in my Mark-3 - the mechanical pump on the 912, and a Facet electrical pump. Just because I can! (Since I built it.) Call me chicken.

I'm not terribly worried about ethanol, since all I can get here is 10% ethanol gasoline, and I've had no problems other than the need for jetting adjustments, but since the first part of the message referred to concern about ethanol, I was pointing out that drygas IS alcohol (isopropyl, or sometimes methyl). -Dana -- Be wary of strong drink.

All the chemical compatibility information I've found shows PVC compatibility with unleaded gasoline and ethanol as only "fair"... "good" for leaded, and "excellent" for "high aromatic gasoline" (whatever that is). CPVC (the typical tan plumbing pipe) is listed as worse, only "fair" for all types of gasoline. Makes me leery. -Dana -- Be wary of strong drink.
