size=2>Hello John,</FONT></SPAN></DIV>
<DIV><SPAN class=053083816-13052004><FONT face=Arial color=#0000ff
size=2>That's interesting ... have you also tried a hopper tank? I had great
success with one in preventing air-gulp hiccups with other engine setups. The
hopper is a small (2 ounce) tank plumbed in series between the main tank and
engine. Its clunk only runs to the middle of the tank, so that it can never
uncover, until more than half emptied. The Hopper starts life completey full
as its overflow is connected to the main tank pickup, and stays that way
almost until the end of the main tank. Air gulps take a bit out of the
hopper, but as long as they don't make it more than half empty things are
good. Its cheaper, and does not require fancy tank filling procedures. Given
the weight of the bladder it might even be lighter.</FONT></SPAN></DIV>

ect. Not until I went to a Bladder tank{no air in media} did the engine run
flawless. Since then it has never even hick-upped. </FONT></SPAN></DIV>
<DIV><SPAN class=004212816-13052004><FONT face=Arial color=#0000ff size=2>It
is of my opinion that the DZ will not tolerate any air in the fuel delivery
