Hey guys! Im having the same problem with the 1/4 of gas shut off.
Has there been any update on this? Also how many miles are you guys getting on a full tank? becuse of this issue I have to track when to fill up by how many miles I drive rather then what the fuel gauge says. Thanks in advance for the feedback

Do you have the inline setup? Something is probably blocking your float. Mine randomly went away after a month so the pump probably shifted to a sport away from the float.

HAHA I just pulled the pump this weekend and installed the stage 2 pump. Much less headaches that way.

What I found on mine is that when I was trying to take the clip off that large vent tube I pulled hard enough to get my hands in there that I pulled the hose off the hat side connector. When I put it back on it didnt seat as well as it was before, but I figured it would be ok.... turned out it wasnt.

I stuck my hand down into the tank and fallowed the tube to the "breather vent" and it seemed to still be connected to that guy just fine, but just to be sure I put a hose clamp on the hat connector to make sure it wouldnt leak anymore. I had to be careful about how I put it on too. The hat connector has 2 stages of "barbs", one big barb, then 2 smaller sets of barbs. I had to make sure I put the hose clamp closer to the connector elbow so the clamp didnt go on top of the large barbs but only the small barbs which then forces the hose to seal by pressure against the large barbs.

Sadly in the process of this I busted the nipple on the fuel feed line and am having to replace the fuel feed line and passenger side hat/filter, so I cant test to see if me blowing the lines out and putting the hose clamp on fixed the issue until parts come in on tuesday.

When I pulled the fuel feed line I saw the white tube you're talking about that goes to the throttle body. I bet under partial throttle when you're at vacuum if your vent lines are filled with some gas that the gas will get sucked into the throttle body through that tube and cause the "stumbling" due to being rich like I am having.... guess it helps clean my valves? lol. But under boost you will never get the problem... explains why no issues at higher throttle %.

Old bump.

What did you do to blow the vent lines out? I'm having stumbling issues and wondering if fuel getting into the vent lines caused this problem. This started after my stage 3 install, immediately after. Can anyone suggest a method to ensure the vent line is clear of fuel. I'm positive the vent line is connected, I've checked it 3 times now.

I put my mouth on it and blew many many many times. I also disconnected the portion of the system that connects to the throttle body which also let me blow air that way as well. I stopped once I could no longer hear/feel liquid in the lines when I blew, then put a nice SS hose clamp on the thing so it would never happen again.

Since then, no issues.

What's end did you blow into?

I'm the lpfp area, the top hat hose?

The throttle body hose?

I blew into the part that connects to the LPFP hat, as that's the normal flow direction through there.
