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

<DIV>I have no idea where or how to get pipe pressure off a greeve
pipe. I read somewhere that another option is to get pipe pressure off
the header. But there ain't any way I am going to touch my custom hand
made header with a drill bit. Was thinking of mounting it over the
fireplace anyway.</DIV>

<DIV>I really like the hopper tank as a straight forward solution. With
no moving parts it must be very reliable. It would be very easy for me
to modify the battery holder just behind the firewall that I have now, over to
a hopper tank holder. I have to move the battery back anyway to balance
out the swap to an OS160 from a Webra145.</DIV>

<DIV>There's absolutely no trick to the topper tank arrangement Wayne has
referred to. It is simple set-up and works as well as any pump set-up on the
OS160 sport engine. I have been using a 16 oz over the cg (standard tank,
not 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 tank feed to topper tank vent; topper tank feed to carb.</DIV>

<DIV><FONT face=Arial size=2>On the ST2300 if you use the Perry pump you
also need to use the Perry carb. I have one now that I am still
running and once its set I had to barely make any adjustments over the
whole season. Putting it in a Funtana 90 right now...should be a
blast!!</FONT></DIV>
