Spectra brand pumps are smaller (in every dimension) than your original Airtex unit -- you could try one of those.

Is your new Airtex pump itself the same size as an E8012S? If so, you should be able to install it in the same place (you may need to tap your carrier 1/4 NPT rather than adapt the pump to 1/8 threads.

IIRC, Steve went through a phase of relocating his pump elsewhere, but ultimately decided to go back to the tank -- perhaps he has some insights.
