Which carter pump for LP pump?

[Tanner]

Which carter pump is the LP fuel pump? The specs look the same on these two, so I'm having trouble distinguishing...

Carter P4389

or Carter P4070

Although the 4389 says it's designed for 12V marine systems.... Only difference I see. Anyone?

[boatwakes]

4389 is ignition protected for marine engine compartments, 4070 is not. $35 difference...Kaboom!

[Tanner]

Actually like a $120 difference... $59 vs. $179 .... but yeah I figured that was the situation.

[boatwakes]

They carry it at jets.com $115 for the marine and $89 for the universal.

Replacing a low pressure fuel pump on my MP 5.7 340hp.. will this Carter P4389 work fine or should I do the Marine power brand part # MP 438108?
