Default running rough hesitant.

I've got a 2007 dyna superglide. Have s&s 583 cams, 106 kit, se heavy breather, v&h 2 into 1 comp pipe and pcv.
During running in of bike started to run rougher and rougher. Finally got to dyno tune, found fuel pump not getting to pressure. 30psi instead of 60psi. All replaced and dyned. Seemed to run ok but still hard to start. Now 400kms later its playing up again. Hesitant when running, maxed out at 70mph and couldn't get anymore out of it. Will take back to dealer but thought I'd see if anyone had any ideas. Maybe pcv. Have pc3 I can put back in to try.

holes in the in tank fuel lines will do this if it runs good when full and shitty when not full.

Checked out fuel lines but seemed ok. Think I've found issue. There's sand in thebottom of the tank. This may have been what damaged the original fuel pump. Will clean out tank and get fuel pressure checked.
