Yes, if you search Reo accelerator pump on the Holley site, it will show up. That is where I got the picture.


I was looking for a picture of a Holley on a Reo. Found one on the SteelSoldiers forum, but I needed to be a member to enlarge it. I did join, nobody there today for confirmation.

From an Ebay ad. You can see the bigger pump and app list

You did find one with the original style pump! No inset screw heads.

From AI:

AI Overview

The Holley "REO" accelerator pump is a heavy-duty, 50cc fuel pump assembly (typically part number 20-11) designed for high-horsepower engines, alcohol/methanol-fueled applications, or extreme-load situations. Standard 30cc pumps are usually adequate for street driving, but REO pumps provide a larger, longer-lasting fuel shot to prevent engine bogging.

Key Details & Upgrades

• Part Numbers: Complete conversion kits and replacement parts can be found on sites like Holley Accelerator Pump Kits on eBay.
• Tuning Cams: The pump can be further calibrated using Holley Pump Cams (often part number 20-12), which change the lift and duration of the fuel squirt.
• Nozzles: Upgrading to a 50cc pump usually requires matching Holley Pump Nozzles to handle the increased volume effectively. [1, 2, 3]

And why do they call it a fuel pump? It is I guess of sorts, but the instant I hear accelerator pump, I know EXACTLY what you're talking about. You tell me 50CC Fuel Pump, I'm going to say, HUH?!?!?
