In my normally aspirated Aztec I'm getting only 17-18 gph on the left during takeoff . The boost pump is just a couple months old. I replaced it because it sounded terrible and I was barely getting any fuel flow during the prime. The new pump sounds good but there was no change in the lack of needle movement when priming. Now I'm not getting full throttle fuel flow on takeoff. The fuel injection systems were sent out and rebuilt about a year ago . I suspect the gauge at this point. I wanted to swap the connections on the gauge and see if the problem stays on the same side . When I looked at the gauge I was thinking there would be 2 connections but there are 4 I think . Do I need to swap all the lines or just the 2 from the engines? The others are vents correct? If the vents were clogged that could cause a problem also????
The engine seems to run fine.
Any help would be appreciated.
