(Bill Gunn) ________________________________ Message 1 _____________________________________ Time: 05:23:39 AM PST US From: rob ray Subject: RV4-List: Re: Fuel Pump Mounting and OAT... --> RV4-List message posted by: rob ray Wally, I mounted my fuel pump as you suggest, for a level flight attitude, 1500 hours ago...still works fine. While you're down there, hinge a door over the battery compartment, buy an odessey battery and mount it out on the firewall and turn that area into a forward baggage area.Save yourself 10 pounds, have better cold starts and save some space as well. Forget a center console between your legs, adds weight, takes up space and is completely unnecessary. Put plenty of firewall insulation under that floor while you're there as well, especially if you use a Vetterman 4 pipe. You might as well route a 1" scat to the back seat through the stick well and have rear seat heat while you're there as well, you'll wish you had it for your back seat cutie in the winter.Make a nice diverter scat where the heater enters at the firewall and forget front seat heat, have it come out behind the front seat, much better. And....while you're back there, build up a set of rear seat footwells, you' ll wish you did that too. OK, while you're there, might as well get some decent stainless braided NAPA brake lines too. The plastic ones started leaking after 5 years. Be sure to route a cooling scat to your avionics too.Have several good fresh air vents too, I like the Vetterman "turn-out" vents, 4 is perfect for summer flying. Why do I babble about all this, that is every change I made AFTER I started flying it. I bought a Wal Mart automotive OAT and put the sensor out one of my fuel tank vent tube holes. If you use a standard aircraft OAT, I have seen them mounted with the sender sticking through the inlet of a standard Vans fresh air NACA duct. Really, you could put it anywhere above the fuselage water line and get good results. Good Luck!

Knowing this pump is an automotive pump, is this also important in an airplane? Seems like the pump will be at a 45 degree angle most of the time in a tail dragger, at least for take-off. I had planned to mount it in a manner that would make it level in normal flight. 2) Where is the suggested mounting location for the outside air temp sensor? Thanks for any suggestions.

You say " Put plenty of firewall insulation under that floor while you're there as well, especially if you use a Vetterman 4 pipe." I am a bit puzzled here. Is this to keep you feet warm or cold? Is the heat coming through the firewall or is it just radiated heat coming of the exhaust pipe tails? I am puzzled because its mostly fresh air under your feet. Re ".the back seat cutie" I have decided to solve this problem with electric seat inserts. I decided I just did not want to start cutting holes in the spar, especially when VANS were not prepared to say exacvtly where. (Phlogiston said they were more than happy to cut the hole if VANS would just define where. They would not.) I just mention this for the sake of other builders, since I spent ages trying to work out how to safely get heat back there. Finally where did you put your oil cooler? On the back of the baffles (LHS), hanging from the tubes of the engine mount, or on the firewall? Do all these locations work equally well?
