Where can I safely blow air thru fuel lines?

[Matt Bachand]

I need to find a fuel delivery problem, possibly clog.

I want to blow low pressure air 3 psi or so through fuel lines to clean them out.

Can someone tell me where is the best place, and the easiest method?

Can I blow air backwards from the t-valve?

Can I blow air forwards from LP Outet into fuel manager?

Can I blow air backwards from LP Outlet into tank? (To clear crud outta LP)

Someone please tell me what methods are safe, and what not to do. Thanks.

I have blown back through mine about a million times near the rear driver's side wheel. I broke into the fuel line and put a tee valve in. Clogged sock is my problem.

Take off the Lift Pump and blow into the line exiting the tank...

blow back into the tank. Just remember to remove the gas cap first so you don't build up pressure and ruin you fsu.
