    Fuel pump assembly for Ecotec atoms

    Terry is credited for finding this a while ago. Posting here for my future reference. Fuel pump assembly.

    Any idea if this is the same pump/sock/filter/regulator as the early Honda-powered Brammo AA2s?

    I've asked TMI a couple times now for details on the older AA2 models and they're not being very quick on the info. My Summer's getting short here, I need to get a fuel issue sorted before it's uncomfortably cold.

    I'll speculate until Terry answers.

    I dont see why it would not work. I imagine brammo had the same shape tank and opening. Just a power and ground wire to the pump and 2 wires to the level sensor. Does yours look like this?

    I haven't looked in an age and it's a rat's nest of crap behind the firewall and under the intake manifold. I'll see if I can put a camera on the macro function and jam my arm up there to get a peek.

    Got any pictures of the fuel filter too? IIRC mine's about 1.5" in diameter, about 3" long, with 1 line going in an end and 2 coming off the other (three hoses total). I think it's a Cobalt part too.

    TMI just called and they had some GM part numbers for the pump and filter:
    GM# 15245454 pump assembly
    GM# 22734980 filter

    I've not really looked them up yet to see if they look like what I have. But this: New Genuine GM Fuel Filter P N 22734980 Chevy Cobalt G5 Pursuit Saturn Ion | eBay doesn't look the same as mine from what I can remember...

    *sigh*

    That GM part number for the pump assembly is the same one I linked above.

    I dont have pics of the fuel filter since I replaced mine a long time ago with an aeromotive one. But that looks right. But in the ebay pic above (I guess it is no longer available on ebay) it includes the filter with the pump assembly.

    I bought the same pump/filter assembly as was specified for the Ecotecs back when I replaced the seals on my fuel tank. Your car probably uses the same part, too.

    I agree. The dash is the same on both GM and Honda Brammo cars, and the ECU isn't involved.

    The pump in the first post was a steal of a deal at $125, but the seller doesn't offer them any more. They were actually from recall repair kits for the Aveo, which is why it included everything shown in the picture.

    If buying a replacement pump - be careful. The 2005 and 2006 versions don't interchange - the wiring harness connections were changed. As far as I know, all Brammo Atoms use the 2005 pump.

    50˚F is great weather if I'm not soaking wet with windchill on top of that. For me, "uncomfortable" starts at about freezing if the sun's out. I have maybe another month and a half before the cold fronts start blowing through and the grippy Summer tires start becoming a liability.

    Thanks Bolus, Karl and Terry, I'll see what's what as soon as I can. Hopefully it's not the pump itself and just the sock/filter.
