2002 Indmar Assualt TBI fuel pump replacement

Replacing the fuel pump on my 02 Supra Launch, has the Indmar 320hp TBI engine. I know some of the mid to late 90's mastercrafts carry this same engine so figured I would give it a shot here.

I've been on the phone with Indmar all day trying to get some direct answers on which fuel pump I need. I have not gotten a straight answer but only a recommendation.

My first questions is, does anyone know how much turnkey pressure is needed and how much running psi is needed on these motors? I have read in the chevy truck forums that it should be around 12psi running lbs, but that does not take into account the low pressure pump in my stock setup.

Second question is which of these three high pressure pumps that I've researched seem more appropriate?

Carter 61157
-Max running 25psi
-Static psi 40lbs
-20 gal/hr
-$115

Carter 61171
-Max running 43psi
-Static psi 120lbs
-30 gal/hr
-$70

Indmar s495126
-specs unknown (even Indmar said they did not know and that this is the closest thing they carry to the stock pump that is no longer manufactured).
-$270

I have read elsewhere that someone whom replaced their pump with the Indmar pump now has a poor running condition, guessing too much or too little psi. All three pumps resemble my exact stock pump. Any info would be greatly appreciated!

On my 2003 Indmar predator TBI, I used the airtex e2065. There's a big long thread about fuel pumps here https://www.mastercraft.com/teamtalk...=25783&page=76

and an install guide here

Anyone good with wiring? I've found a peculiar situation, when both pumps are plugged in my fuel pump fuse blows. When one of the two is plugged in, the fuse does not blow. I've been told this means one of the pumps is drawing too much juice. I've now ordered a new low pressure pump in case that's the culprit (third pump I've ordered now between the high and low pressure pumps). Any other input would be appreciated. Thanks.

Solved: bad low pressure pump - pump was drawing too much juice. Replaced the low pressure and high pressure pumps part numbers p4388 and p5001. Thanks.
