I just had fits using a stock replacement Carter fuel pump. It was some made in malaysia POS in a Carter box. It ran good for about 2 days then started having choking issues. When I put on a clear filter, you could see the lousy flow. I took it off and the pump arm was scortched. I think the casting was off a bit and misaligned the arm. Put on a Carter HP mechanical pump and all is well. Sent the other back to summit for my $$$ back.
