![]() An auxiliary pump is required for engine starting and as an emergency back up to the engine driven pump. ALL of this can be replicated on inexpensive hand versions. Auxiliary Pump P/N 2090255 Airflow Performance, Inc. Reverse is true for the CNC bender-a special short leg bend die puts the flare close to the bend centerline. For our production equipment, we designed special flare dies with large counter bores so a pre-bent tube could be flared without the dies contacting the ben. At the same time, I have a modified RFT 37, with the aft side of the flare bar 'relieved' so the bar can be closer still to the bend. ![]() I have several hand benders modified this way just because they are fast for doing mockup stuff. Doesnt matter if you have a single size bender, like an Imperial 364 series, the triple header version, or something from Harbor Freight. The real trick is to use a bend die thats modified to allow the flare to be moved closer. This helps to move the flare closer to the bend. Called the IO-390-EXP119, the engine is rated at 215 hp and provides, according to Van’s, a significant upgrade in performance over the standard-issue IO-390. The relief valve (25 PSI) is built on to the boost pump package. This type of pump requires a relief valve to bypass fuel when the pump is running, which keeps the pump cool and sets the pressure to the system. Rigid makes a RFT37, that has a flare bar that about. A more powerful, lighter-weight variant of the angle-valve IO-390 has become available for the two-seat RV-14/A. The Airflow Performance aircraft boost pump, P/N 3090050 uses a high-pressure roller vane type fuel pump. So you have the actual distance from the start of the bend-actually where the tube bends and the dies interfere with the curve, and there the flare section of the dies are. The other part of this is that most builders have a Parker Roloflare, and the dies section is about 1 inch. PUMP INSTAL', which includes an Airflow Performance p/n 3090050 boost pump package, an Airflow Performance p/n 1090079 fuel filter, and various parts for installation in the cockpit. Well, if you flare the tube first, then you are limited to 1.75-2.0 inches from the flare to the bend centerline. The other issue is that once the tube is bent, how do you get the flare close to the bend? If you use this air box, you'll need to cut it down on both ends, but it will fit perfectly and leave clearance between the air box and the scoop for a rubber duct interface.Most of the inexpensive benders can bend a 180*, most are limited to about 120*-135*. The best info I could find (and I'm not sure how good this is) says that the filter provides 450 CFM.seems a bit optimistic, but according to the calcs, my engine would require about 289 CFM at 2700 RPM, so I'm thinking I'm ok.that and seeing the same setup on a Reno air racer made me a little more confident that this will be fine. The air box I used was the Spectre Performance 9833: Still it requires a few carefully aimed expletives to get it all in place. I made the scoop removable which helps a lot.the 3 blade prop is a bigger PITA than the scoop. This a maintainable filter incorporating a 125 micron pleated stainless steel filter element with a anodized aluminum housing. Details This a maintainable filter incorporating a 74 micron pleated stainless steel filter element with a anodized aluminum housing. Clean air is of particular importance for young children and elderly adults. People with chronic respiratory conditions or allergies also need clean air to remain healthy. I have all of the hoses from Steve and they are exact fit. 0 Comments Regularly changing the filter leaves indoor air void of small and microscopic particles that could impair health. And as Steve at Aircraft Specialty mentioned, several of the kit hoses are not the best fit to the FM-150. The filter Airflow Performance recommends for this application is P/N 1090079. Airflow Performance has these bracket kits available now, mine is on the way These will make the installation much simpler than doing the engineering yourself. Just looking at your site - seems very clear and very clean. This again depends upon the type of fuel system in the aircraft, returning or non-returning. How hard is it to remove the bottom cowl? This auxiliary pump is designed to be installed in series with the engine driven fuel pump. Mark, I'd love to get as many pictures as you have, that would be great! Pump Only Details RV-8/8A builders with pre-punched fuselage kits from Van's (shipped since 2007) do NOT need to purchase an installation kit, only a fuel pump ES AIRFLOW PUMP-1 and filter ES AIRFLOW FILTER.
