Jim,

I just got the notice today that my pressure fitting is being shipped. I can't remember if you've been in the "Tachometer" posts about the 1.60. If not, check it out and see what I did with that other shouldered hole.

I'm also curious about running crankcase pressure.... or what about both? Muffler and Crankcase?

FYI, I installed the pump the other day and will hopefully test it tomorrow.

Hal,

Thanks for the insight. I have already installed the large fuel tube and stopper assy, which comes with a bigger clunk and bigger tubing.

As I was going to move my tank to the CG (but it was going to be too much work undoing what I've already done), I put it back and noticed something. I had the tank (a slanted sullivan) surrounded by foam. It is possible that the hoses were being smashed by the foam at the front of the tank. Just a slight possibility, but I re-did my tank install a little better..... hopefully.

I pretty convinced that the muffler is causing all my problems. If you look at how much restriction is in a stock muffler, it would make sense that there would be more muffler pressure because of it. Just the fact that the stock muffler has 1/4 of the outlet of the Slimline, PLUS it has a baffle in it.

Anyway, all this is speculation. I've got a stock muffler coming in the mail thanks to RCU! So if this pump doesn't work (I think I'm pretty safe there, though), I will be able to test my stock muffler theory.

OH! Jim, I'll go take some pictures right now. I would recommend cutting open the bottom covering to see where your pull-pull wires are going. I think there is a frame brace that my kevlar might be rubbing against. I've got to check it out. Also, my cowl is not perfect either. I'm really not bothered by it, so your engine may be ok. My landing gear seems pretty straight to me, but honestly, I may not have noticed. I'll check it out.

Thanks for the interest and keeping this thread going.

Mike
