small pressue pump for diagnosing needle and seat problems

Would anyone have a place to buy a small pressure pump with gauge to check needle and seat issues for carbs??

MityVac makes small handheld vacuum pumps that folks often use to check them. Many auto parts stores sell them.

pressure pump

Yeah, I have one Cheese but mine doesn't do the pressure side.I guess you could put vacuum on it but would you get the same result as putting the pressure on it.
I just use a small hose and blow thru it now. How about you?

I connect them to a gas tank and check them under the exact conditions they will be in if I have one that I'm uncertain of. I normally don't even check them prior to installation unless I have reason to suspect it will give me a problem.

I've always found blowing in a piece of clean fuel hose to be good enough...but I suppose some day I'll run across one that leaks <just a little> and won't be detectable that way.
On my cheap plastic MityVac the pressure side is the same size hose stub as the vacuum side and can push or pull.

The needle and seat

Take an outboard motor fuel line, they have a squeeze ball that should generate enough pressure to make a float needle leak if its going to. You can usually find an old one at most any outboard/marine shop. You might have to do some adapting to get the size right. Mind the arrow on the ball.
