Skidim has it on their website, and it appears to be the correct part number, but they are asking $328 for it. If it is just one of the Carter pumps, which it looks just like it, then they are only around $100.

It's like I said, the Indmar 501006 low pressure pump is LITERALLY a Carter P4594 (or a P4389). It's not a other brand cross referenced part. I have seen prices online for this pump from around $200 to over $400 (skidim has it for $212). I can buy the EXACT same pump from Summit or Jegs for $56; Rock Auto has it for $51. There is no way indmar MADE the pump, it has to be some other OEM fuel pump manufacturer, and if they used Carter for the low pressure, then chances are good that it is a Carter as well. I am fairly confident that it is a P61171, but I can't figure it out for sure. Anyone else have any ideas?
