Holley Sniper 4150 EFI 800 CFM Self Tuning & Programmable EFI SOLD

Up for sale is a used Holley Sniper Self Tuning & Programmable EFI set up Part # 12440B.
Asking $600 obo (cost $1500 new).

Its in good condition & works great; was running great when pulled a few months ago. It could use a cleaning.
Pictures are of the actual pieces for sale. Comes as pictured.

Will be shipped via USPS Priority Mail or FedEx; whichever is cheaper on my end.
Also: Pick up in Godley Texas 76044.
Email me and we can set up a time to purchase it.

Please make sure this will work for your application before purchasing. It will need appropriate fuel pump/relay for your custom set up. Both Holley, and here on TGO have lots of good info on installing and using these EFI set ups.

All the best, Kyle.

Thanks!

Hey there,

It was purchased in late 2019/early 2020 (not sure on exact date, it was before lock-downs). It is original as it came from Summit; never been sent in.

All the best, Kyle

The reason I ask is the earlier units are prone to failure, I have had mine fail twice.
Mine was purchased about 10 years ago.
So if it fails you send it in and Holley fixes it for free with the latest upgrades.

Re: Holley Sniper 4150 EFI 800 CFM Self Tuning & Programmable EFI 12440B

Just to clarify, I’ve had several people ask me about the part reference #.

Apparently Holley does not stamp it on these units (I looked on used ebay set ups; they all are like mine… a variation of a white label on the side saying “90024 0579" and have "12440B" stamped next to that white label.

Anyway, the reference # for this Holley is: 550-511 Black.

Here is a link to the Sniper set up I purchased in 2020:

Holley Sniper EFI 550-511 Holley Sniper EFI Self-Tuning Kit - Black

Here is the installation manual:

Hope this helps with research.
