The part # I was given from the parts department at the dealership is 19180114. When i search that part# in Google and ebay they all start around 300-350. The alternate AC Delco part#MU-1726. The price on them listed is around 250 when typed into Google. Are they same part listed with different numbers because one is the manufacturer and the other is the retailer or is AC Delco the aftermarket part?

Some stuff Delco makes, some stuff they buy and label. They are pretty good at hitting their quality standards, which are usually good.

Depending on various factors the part they sell as Delco - i.e., this fuel pump - may be OEM or may be good aftermarket. Delco's always had its own numbers for parts and when you get the part in the box it is as likely as not to have the GM number printed/stamped/molded on. I suspect the Delco pump is aftermarket now, unless you get NOS, because it's been a while since the Riv was made so you would not have OE production runs to box up as repair parts.

There are pump replacement kits for about $50 from ACDelco that just replace the wear parts, they are fiddly to install but supposedly work well. When my OE pump quit I got a Carter after learning the dealership was replacing the OE pumps. That is, a car they'd put a replacement OE pump on would be back in 18 months or so for another. Didn't have that problem with the Delco parts kit, or the Bosch or Carter pumps.

I used the Delphi pump. Looked exactly like the OE pump I replaced. The only difference was you had to rewire one of the pigtails which they supplied, very easy.

Generally can't go wrong with Delphi; Delphi in some cases makes the Delco parts and in some cases does not.
