I have an 83 GT that I am finally making some mild modifications to after 25 years! I bought the car new and it is in excellent shape. Anyway, the factory fuel pump is leaking oil out the vent and I want to replace it with a Holley 80 gph performance model (12-833) since I am running a Holley Street Avenger 670 carb. On the Holley website it shows this model with a vapor return line(and all the required fittings), but I have order two - one from Summit and one from Jegs - and they both came with just the in and out lines (and no fittings)even though it is the same model number as on the Holley site.Summit said they only carry this model because the pump is usually going on an already modified fuel system that no longer has the vapor return. Jegs showed the same picture as Holley, but sent the same pump as Summit. I've submitted an inquiry to Holley to see if I can just abandon the vapor return line and am awaiting a reply. I thought I would just post out here too and see if anyone has had any experience with this switch.

I still have A/C too. Any suggestions would be appreciated!

Thanks

Just go with the stock replacement, it will work fine with what you have done.

I hate it when a post doesn't follow up with results, so...
Holley said that their pumps should work fine without the vapor return, but since it would have required some changes to my out line to the carb, I just did as Gary H suggested and put an OEM replacement on and it keeps up just fine with my demand.
