I've been working on a 49 Willys that I'm swapping an 85 2.3L into. With the EFI delete comes the need for a new fuel pump. I've tried a couple of different mechanical fuel pumps from different year Rangers and Mustangs none seem to work with the lobe on the 1985 auxiliary shaft. It looks like a 1974 pinto fuel pump would work...does anyone have any experience with this kind of swap? Any thoughts or ideas would help. Thanks in advance!

Are you absolutely positive it has a true fuel pump lobe? As far as I know there are only two auxiliary shafts, with lobe and without. The fuel pumps are all basically the same except Rangers are designed upside down. My block came from an '86 efi Mustang. It had a fuel pump block off plate on the block and sort of a different section on the shaft but no real lobe for the fuel pump. I ended up using an auxiliary shaft from a 2.0 Ranger since they all had carbs and mechanical pumps.

Yes, +1 ^^^

AUX shaft with distributor gear came in two types, for 2.3l only or for 2.3l and 2.0l <<< this one has the fuel pump lobe
1985 2.3l with MFI(EFI) wouldn't have the lobe

Seen here: https://www.ebay.com/itm/Ford-2-3L-2-0-Auxiliary-Distributor-Shaft-Ranger-Thunderbird-Turbo-Mustang-SVO-/202665499698?oid=173543112940

No reason you can't use an electric pump.
If you are using it off road then I would add a relay that is Grounded by an oil pressure switch, and that relay starts the electric pump
That way if there's a roll over or broke fuel line the engine will stall and fuel pump will stop pumping

Definitely has the lobe, but I'm thinking electric might be my best option. I'm wasting a lot of time and energy on finding the right mechanical fuel pump.

That's definitely it. I really can't think of what the problem could be. Ranger pumps set where they look like they're upside down. Most cars hang down like a traditional Ford fuel pump.

Here's a pic of a car fuel pump. They go the other way round. They have a curved pump rod while Rangers are straight but they all use the same auxiliary shaft though.

What year was the 2.0 you robbed that fuel pump from? I'll give that a shot.

It was a 1987 Ranger 2.0.
