<DIV>I thought the FL-70 had a new system to pressurize the fuel tank. Do you need the perry pump?</DIV>

<DIV>Do not think I would run both a perry pump and the aeropressure thing that OS is advertising with the FL-70.</DIV>

<DIV>-------------- Original message -------------- <BR><BR>> Use the line that would go to your muffler as a vent. If you are drawing <BR>> fuel from the tank, via a pump, you need a vent to equalize the pressure in <BR>> the tank, so as to not cause a vacuum. If you are sucking the fuel out, you <BR>> need to allow air back in. I normally fun the line straight down and out <BR>> the bottom of the fuse, attach the line with a clamp to the firewall. You <BR>> can also put a check valve in line to allow air to enter and no fuel to <BR>> exit. <BR>> <BR>> After all of this, I never asked, do you already have the tank vented? That <BR>> should have been my first question. <BR>> <BR>> One more thing, I've run the Perry VP-20 with muffler pressure, it works <BR>> great. I believe the VP-30 says not to use muffler pressure. <BR>> <BR>> Ken <BR>> ----- Original Message ----- <BR>> From: "Jay Marshall" <LIGHTFOOT@SC.RR.COM><BR>> To: <DISCUSSION@NSRCA.ORG><BR>> Sent: Sunday, December 04, 2005 7:48 AM <BR>> Subject: Pump <BR>> <BR>> <BR>> > Just installed a O.S.
