Default H3T 3.7L 5cyl wrong fuel pump

Just wanted to warn everyone that Bosch lists their 67791 as fitting the 2009 3.7L 5cyl. It doesn't. I will report back when I figure out what does.

I have ACDelco on order. Which connector is going to be a problem?


Edit: I don't see any related part listed.

The pump is still working. Truck has 118K on it. Pump has been whining for the past year, fuel pressure gauge shows fluttering and the wife said it "bogged down and wouldn't go" while cruising down the road. It could have likely lasted months yet.

I thought I would try something different this time. Usually I'm the one in the high mileage vehicles and I ignore all the warning signs waiting until it has a full tank and is stuck on the side of the road somewhere. Factor in RA showing only 2 ACDelco pumps left I thought a would just take care of it before winter sets in.

This is the Bosch 67791 with the screw in fuel fitting that did not work on my 3.7L 5 cyl H3T. Bosch lists it as compatible, so all the vendors do as well.

I selected it for the metal lid and the Bosch reputation. If the pictures provided by ACDelco were better, I might have noticed they were different.

This is the ACDelco MU1879 that did fit my 2009 5 cyl H3T. There were no issues with the electrical connectors that SYCRAFT suggested. Everything plugged straight in and the truck is running noticeably better with stable fuel pressure as an added bonus.

Note: This is a protective shipping boot over the fuel line connection if that is not obvious to you in the picture.

My truck has a March 2009 build date. Anyone that has replaced the fuel pump please post the build date from the door sticker, engine and whether yours had the screw in fuel line or the vertical quick connect. As GM lists only one part number for all years H3T, I am curious if this is engine or build date related.
