If it were me, I'd shop for it on RockAuto. Spectra will probably be the more common option. I've used their sender, which is fine, but I've never used the pump. Pump's and pump/sender assemblies are way overpriced at a parts store. You can buy a whole new assembly there for anywhere between a third and a fourth of what you'd buy the same exact thing for at the parts store. If I wasn't in college, I'd probably try the Walbro pump and either reuse my GM sending unit or buy a Spectra sender from RockAuto.
