Dauntless Fuel Pump, Not sure of engine year

[Spudbutter]

First post here! I just got a 1955 CJ5 handed down to me with a Dauntless Buick 225 V6 V6 225. I have it running great but the fuel pump is leaking. I'm not sure of the year of the engine. Here is a pic, can someone point me in the right direction to replace this particular fuel pump. On ebay, they all look different.



Thanks!

The fuel pump for the Dauntless Buick 225 V6 225 would be 1966-1971 CJ5 jeep.It will come with three lines: inlet from tank
outlet to carb.
return line to tank
The return line was to prevent vapor lock from heat. I see a lot of jeeps not using return line so I guess it's not mandatory for operation.
The pump you have is probably for a 231 Dauntless Buick 225 V6 . As they have only in/out lines like your. mike

The link below looks like it might be the exact pump from a 1963 Buick Skylark. A 225 with two lines. The engine was added sometime in the 70s so it might not be a "Jeep" 225. It might not even be a 225, IDK! Thoughts?

Mike- Thanks! If it is that old Skylark motor, is that an oddfire? It's so new to me, I'm trying to do my diligance but don't know much about Jeeps yet.

Yes all 225 v6's were odd-fire. buick redesigned the 231 v6 to even fire in 1977 model year. mike
