If fuel tank holds vacuum, fault tank vent? My fuel tank is loading up with pressure. My tank vent duckbill valve is pointing into tank when it seems that it needs to be pointing out to allow pressure out. What am I missing? Perhaps I need to look into carb? I own this Stihl 20 years with no issue.
When your testing the fuel system if it holds vacuum then your vent is at fault and needs to be replaced. It Should Not Hold Vacuum. If the fuel tank holds positive pressure then that means you have no positive fuel leaks in your Fuel Tank.
Hi Gary, Just checking a 038magnum at the moment. I understand that when doing the vacuum test it should not hold constant, like your video. What I'm confused about is when applying pressure to the fuel tank should it hold constant or should it hold for a while then drop down to zero after about 30seconds?I cant find a workshop service manual for the 038 mag. Cheers.
Gary will a faulty vent cause this symptom: I have a Stihl MS260 Pro it starts up and runs great and then after less then a minuet it acts like its running out of fuel and dies. Start it up again and the same thing all over again. Thank Phil

0:44 I think you meant 0.7 - 0.8 Bar. 🤣
7-8 Bar would be 102 - 116 Psi. 😀
Agreed. Possibly meant 7 psi gauge. From your info, the difference between 0.7 barg and 7psig is minimal.👍
This is got to be the best explained video I've seen on this subject thank you

Thanks
Hey Gary where did you purchase your pump?

It should should hold pressure. If it doesn't either your fuel tank or fuel line is leaking.

Hi Phil,
Yes a faulty vent could give you that symptom. Just make sure the piston cylinder isn't scored. And FYI I've seen those saws leak from seals.
7or 8 bar?you mean pounds mate xD
