Are you wanting to lower the pressure from the currently installed fuel pump to a lower pressure to the carburetor? Is the fuel pump the diaphram or a rotary style pump?

I really can't afford a new pump, my engine, Lyc O-360 has a pump that is putting out 26 psi. It HAD a pressure reducer when it was flying (I won't go into the details of why I don't still have the regulator). Bendix PS-5C needs 15 psi... So I'm just looking to knock down the pressure. Over & Out!

Gary I think I still have several of them, will have to look in my stash at my hanger? Then give you a heads up. There was a time when the medium pressure pumps were not being overhauled and it was suggested that one use the higher pressure diaphragm fuel injected pump and then use a regulator, I did not want to put another device in the fuel line so went with the correct pump, but hey that's just me.

Ok, it's looks like it would be best just to R&R the current pump with one that puts out 15 psi. On most of the O-360 applications it calls out for the 41271 pump.. But in the Spruce catalog it shows the 41271 pump at 4-6 psi. I can't find one listed for 15 psi. Any recommendations?

What about that link Neil put up in the above post. You can call Tempest, give them a description of your current pump and they can give you the correct part number. There are a least 3 different pump numbers and it has to do with when your engine was built. Since you might have a different accessory case than what was originally installed when the engine was built that's why you need to tell them what part number pump you have so they can cross ref to the proper 15 psi pump. Look at the bottom of the Tempest application chart and you'll see a title showing three differen't pumps under the title of ''Aerobatic Installations".
