But ya know what Murphy says. Yep, mine became a flow loop and gas continued to pour out the canister vent - right next to my hot header pipes and again yes it was 100*F that day. Kinda like a gas shipon it wouldn't stop flowing untill i popped the gas cap. This also caused fuel mixed with carcoal to be feed into intake below the carb on the EVC vent line.
Well since that i replaced that little check vlv. Another story is that when i replaced my fuel tank that check vlv was not availible so i had to go with the original. I already had replaced the original canister before filling it with gas and now have a replacement canister ready as this reminds me to swap the secound new canister in (while i have my splash guard out).

Regardless i still preach using a recirc line for any mechanical pump - using a orifice restriction of course. Keeps the fuel in line cool enough for any weather and fuel pressure stays constant at idle or WOT. If u vent the tank right at the cap - like most of us - u will be fine (to switch to vented cap only requires a vented cap). If u still vent through the EVC becareful not to top off and make shure your check vlv is in good working order. Yes venting without the orifice restriction will make tremendous amounts of vapor inside the tank from the high return line flow rate.:bb

I'm not a fan at all of the Racepumps. Looks neat.....but there are way more people that seem to have issues than anyone with anything else seems to have.
