I also do not like the idea of any oil in the cockpit or anywhere behind th e firewall. I bought an electronic oil sender and gauge combo from Jegs Aut omotive. Nothing but wire from oil sender to the gauge. Cost around 40 to 5 0 bucks I think. I have not yet installed it but if it works on race cars, I think I can make it work on on an overgrown lawnmower engine(A-65).

More specifically, the rear set and the placement of the instrument panel cross struts and plywood stiffener. I understand the spacing between the front and rear (28.75") as this is the spacing between the wing spars when measured center to center. But, if we look at the long fuse print (below), the distance to the front stiffener is... 15" + 6.25" + 23" + .125" (plywood seat back/instrument board) = 44.375" This places the front cross strut right in line (and in the way) of where the rear center strut fitting should go. I am assuming that the center strut fittings mount as shown below (red). If so, I am a little confused about the measurements shown in the drawings. If I choose to move the cross struts and stiffener forward or aft, I'll make for an awful strange looking front seat and headrest (out of alignment). I've looked for detailed photos of this area, but so far I haven't found what I'm looking for.

Plastic pressure lines should not be a problem. You are compressing oil in the line. If hot oil is flowing through the line, that would be something different. The line temperature will be what ever the ambient temp is.

Re the inlet position vertically, better men than I should answer your question, but I think you WANT to capture the water from your tank in your fuel line, then drain it out at your low point-- the gascolator, fuel bowl, etc. If you allow it to collect above a fitting, you may get a fair water accumulation over time, and it could stay separated from the fuel for awhile in operation. However imagine that it sloshes about, then enters the fuel line while you are slipping to land but are short of the field, or you have just tilted pre-flare for a landing, and will want a little burst of power for control, etc. SPUT!!! In other words your engine could sputter and die at just the wrong moment with that setup. My 2 cents. Tim in central TX -----Original Message----- From: Jack Sent: Oct 12, 2010 7:36 PM Subject: Pietenpol-List: Fuel sump question Checked the archives and found nice email from Chuck G that was helpful, but I have another question. For my wing tank Im planning 2 fuel outlets, 1 front and 1 rear. On the rear edge of the tank I will also have a float gauge with a sump drain and a machined sump bowl with a drain. Since the drains and the rear fuel outlet are at the same level, Im wondering.For the fuel outlet should I extend it into the tank a to be above any water that may be present. I understand the drawback of decreasing my tank capacity. Any thoughts would certainly be appreciated! Thanks, Jack DSM ________________________________ Message 8 _____________________________________ Time: 02:43:52 PM PST US Subject: Pietenpol-List: Re: Long Fuse Center Strut Fitting From: "Bill Church" Mark, Earlier this year, I built my fuselage sides, and documented what I did here: http://mykitplane.com/Planes/buildLogReportDetail.cfm?BuildLogID=2535&PlaneID=510&FName=Bill&LName=Church&PlaneName=Air Camper It isn't really clear in the plans, and I'm sure many builders have ended up with the top cross members butting up against the metal cabane strut brackets, rather than meeting the longeron. But, as best as I could figure it out, the cabane strut mounting brackets should be mounted BEHIND the vertical spruce sticks. Only the drawing for the long fuselage shows and refers to the "3/4" x 3" filler for strut fitting". THAT is what the cabane strut mounting brackets should be mounted to, and I believe there should also be another filler block for the front brackets as well (to maintain correct spacing). Bill C.

That is what I will do... I just wanted to make sure that I was looking at the problem correctly.

The idea behind the drains is so that you can get the water out instead of leaving it behind in the tank. Checking the fuel drains for water accumulation was one of the first things on the checklist I used on the C-150/152's I learned to fly in back in the mid-'90's. -------- Billy McCaskill Urbana, IL tail section almost done, starting on ribs soon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=315652#315652 ________________________________ Message 11 ____________________________________ Time: 03:39:39 PM PST US From: Harvey Rule Subject: RE: Pietenpol-List: Fuel sump question Isn't this what the gascolator does and it should be mounted at the lowest point below the carb from what I understand. > Date: Wed=2C 13 Oct 2010 16:26:18 -0500 > From: timothywillis@earthlink.net > To: pietenpol-list@matronics.com > Subject: Re: Pietenpol-List: Fuel sump question > .net> > > Jack=2C > Having drains fore and aft is a great idea. > > Re the inlet position vertically=2C better men than I should answer your question=2C but I think you WANT to capture the water from your tank in you r fuel line=2C then drain it out at your low point-- the gascolator=2C fuel bowl=2C etc. > If you allow it to collect above a fitting=2C you may get a fair water ac cumulation over time=2C and it could stay separated from the fuel for awhil e in operation.

Not sure I detailed well enough. I do plan to have a gasolator with a drain (all don=92t). Also I have two sumps in the tank to allow draining accumulated water hopefully before it enters the fuel line, the sump and drain at the bottom of my float gauge. The reason for my question initially was because of the design of the Stearman sump (picture attached). Note how the sump is below the actual intake level for the fuel. It=92s a great design but I felt too large for the Piet. If I can keep water out of the line before going through the gasolator and to the engine I think that=92s good. That=92s all about clear as mud. Again I appreciate the help!
