<P>Another alternative is a Macs thin wall pressure taps - straight (#9041) or 90 degree (#9051). </P>
<P>These install from the inside of the pipe (thread a wire thru the hole and out the pipe, then feed the pressure tap thru on the wire), with a nut holing them on from outside the pipe. A little JB weld for sealing and security when assembled guarantees no leaks. <BR></P>

<DIV></DIV>>Randy, installing a pressure tap on the thin walled Greve isn't that bad
<DIV></DIV>>except you need to get creative with how to secure the nipple. What I have done
<DIV></DIV>>successfully in years past, was to drill an appropriate hole in the aluminum
<DIV></DIV>>wall and install a grommet and a short piece of aluminum tubing into it. I
<DIV></DIV>>have also heard that some have been successful with epoxying the aluminum tube
<DIV></DIV>>into the hole, but I have not done this myself.
<DIV></DIV>>
<DIV></DIV>>Another option is to send the header back and ask politely for a nipple on
<DIV></DIV>>the mounting flange. Pressure is a little more variable, but the plumbing has
<DIV></DIV>>enough hysterisis to absorb the variation. In fact, that's exactly how my
<DIV></DIV>>present set-up is done.

<DIV></DIV>>I really like the hopper tank as a straight forward solution. With no

<DIV></DIV>>tank holder. I have to move the battery back anyway to balance out the swap to
<DIV></DIV>>an OS160 from a Webra145.

<DIV></DIV>>There's absolutely no trick to the topper tank arrangement Wayne has
<DIV></DIV>>referred to. It is simple set-up and works as well as any pump set-up on the OS160
<DIV></DIV>>sport engine. I have been using a 16 oz over the cg (standard tank, not
<DIV></DIV>>bladder) and a 4 oz behind the firewall for several years in a 12 pounder.
<DIV></DIV>>
<DIV></DIV>>The plumbing is simple as follows: pipe pressure to main tank vent; main
<DIV></DIV>>tank feed to topper tank vent; topper tank feed to carb.

<DIV></DIV>>The instructions on the website are pretty clear. I’ve seen one run on an
<DIV></DIV>>OS 1.6 all summer, and it was flown very hard. It was flown in a 24% Extra
<DIV></DIV>>300 and I have put it through its paces numerous times, and never had an issue
<DIV></DIV>>with it. We ran Cool Power 15% through it, and I don’t remember ever having
<DIV></DIV>>to touch a needle. I saw Bob is no longer recommending this, and he has a
<DIV></DIV>>lot of runs on his OS 1.6 with the Perry pump, however I ran that Perry pump
<DIV></DIV>>on a Super Tiger 2300 and could not get it to run consistently at all, so I
<DIV></DIV>>guess its all a matter of personal preference, just like anything else we do…
<DIV></DIV>>the only thing you would ever need to replace would be the diaphragm, which
<DIV></DIV>>they will replace for free.
