That's pretty much the last of my Milwaukee stuff I use, besides the corded hammer and hole shooter drills. No more battery stuff. The battery stuff is about the same as your arsenal , -20v DeWalt and larger. I can't remember what the hedge clippers (DeWalt) are. 42v maybe (?), well, those things will shear right thru 3/4" branches like nothin lol. Those little 20v brushless impacts can take a hell of lot of abuse, - keeps taking it. My 1/4" is old now, I use that one most, but man, was that worth every penny!

The fuel will come out while the engine is running, and the pump is pumping. There's no waiting involved.

I must have read the post wrong then. It sounded to me like I had to put the hose on and wait for fuel to come out.

I'm talking about one second versus 17 hours. You should see fuel dribbling or squirting out immediately. You're not still waiting are you?

No, I ended up pulling the hose off and putting everything back together about 8 last night because we had to use the truck.

Untrained if you want to make progress you need to just do the stuff that matters. On topic. Doesn't really matter what time it was or what you had to do. I think that's why the other guys are talking about their power tools instead of your problem.

You said that you were "waiting" yesterday, 17 hours ago. Did you wait for more than one second? One one thousand.... Did any fuel come out? If not, then your FPR probably does not have a leak.

Good luck. Focus.

I waited for a couple hours. I checked the bottle more the a few times for fuel.

And...it was dry?

The engine should be running, so that the fuel pump is pumping.

Good luck. Go back and read all of the replies and you might get a better idea of why people are suggesting these things. Think about how the FPR works. And the fuel pump, with its check valve.

It had completely escaped my mind about the way this fuel system is and how it is a return system. It was dry, but because the truck hadn't been running. I understand why the FPR is being suggested, because if it is leaking under pressure then the motor is sucking fuel through the vacuum line. Now I feel dumb.

Post 49, the one and only very quick way to check the FPR...you ignored it.
