Anyone tried to put an auxiliary fuel tank in the rear baggage area in the RV-8?
Any ideas? How can I get the fuel into the engine from there?
Thanks

Yes Juan it can be done!
This tank is my adaptation shamelessly stolen from fellow teammate Robert Gibbons. It's a 16 gallon circle track racing tank. It sits on a ramp to clear the flap actuator tube. Dry break fittings on the hoses allow quick disconnects for fuel feed and venting. The standard Vans fuel selector valve has an unused port that is now used as the Aux position. The hose lays in the cockpit. The vent line is in the aft baggage wall. The tank is strapped down in the baggage comp and via the rear seat belt. With the tank all the way aft there is room to reverse the rear seatback hinge and it will then rest against the mid cockpit brace.
An email with all the listed parts and links.
Wizz,
Here is the list of all the parts for the tanks Greese, Leggs, and I have.
A little over about 500 bucks for the parts.

Smokey and others,
Here is a list of parts and links for the 16 gallon tank I am using:
First is the actual tank
http://www.jegs.com/i/RCI/821/1161C/10002/-1?parentProductId=755349
The dimensions given online do not match the actual dimensions the tank is smaller measuring more like 23 x 17.5 x 11 instead of 25 x 19 x 11
the tank came in a box marked RCI so it probably matches the dimensions for the RCI tanks in the Summit Racing catalog.

For my installation I built a ramp to go over the flap actuator tube 3/4 inch oak plywood measuring 22" long by 18' wide, with a 2" x 3" x 18" and a 1" x 3" x 18" stacked, to support the front of the ramp fwd of the actuator tube, then another 2" x 3" x 18" positioned aft of the actuator tube to further support the ramp mid span
I'll follow up with some pics.

The Jiffy tite fittings are available from Summit but are harder to find online
I'll try to get a pic of the tank installed later today.
