Ive been using it for most everything that needs to be held together kayaks, boats, plane parts, etc. The price for a quart at a time isnt too brutal. And you can add pigment, glass powder, etc. to it. If one can just get the basic shape taped together it will work."

Phil ________________________________ Message 7 _____________________________________ Time: 03:44:30 PM PST US From: Tim Olson Subject: Re: RV10-List: Re: Before the fuel pump exchange - one last question The thing that has me wondering is if the new pressure level is too high. I know that you can buy those pumps in higher pressure versions, which would imply that they are also made in lower pressure versions. I'm wondering which one your needs required. I watched my pressure today on a flight and it was generally 24-26psi. You said yours was over 30. I'm not sure how significant the difference is, but if the pressure was higher, I can at least comprehend that perhaps the additional pressure could cause fuel to be leaked out somewhere. Maybe that's where the blue stain came from and it's all recent? Anyway, I'm sure you'll get to the bottom of it. And when you do, it will be educational for us all, so thank you very much for sharing. Tim > On Aug 12, 2017, at 4:28 PM, Phillip Perry wrote: > > > I did about 2 hours ago.

I know that because the drain line had a blue tint. The low pressure pump runs 4-6 psi for carbureted engines. The model number on mine is the correct model number for the IO-540. I confirmed it from multiple online sources (Tempest, Lycoming, etc.). Also confirmed the correct model number stamped on the pump prior to installing. Frustrating...... While I'm waiting on AFP to get back to me with some ideas, I bought some fittings and a vacuum pump to draw a vacuum on various parts of the fuel system in search for a leak. I'd love to find a cracked flare or something like that and put this to bed.

I agree you have the correct part number which is used on most 4 and 6 cylinder fuel injected Lycomings. It is supposed to have an internal valve of some sort to limit the max pressure by bypassing some of the output back into the inlet.

I know that you can buy those pumps in higher pressure versions, which would imply that they are also made in lower pressure versions. I'm wondering which one your needs required. I watched my pressure today on a flight and it was generally 24-26psi. You said yours was over 30. I'm not sure how significant the difference is, but if the pressure was higher, I can at least comprehend that perhaps the additional pressure could cause fuel to be leaked out somewhere. Maybe that's where the blue stain came from and it's all recent? Anyway, I'm sure you'll get to the bottom of it. And when you do, it will be educational for us all, so thank you very much for sharing. >> Tim >> >>> On Aug 12, 2017, at 4:28 PM, Phillip Perry wrote: >>> >>> >>> I did about 2 hours ago.
