Title: 4053 fuel bowls
Post by: x66 714 on October 14, 2026, 08:54:43 PM
The front fuel bowl was warped on my 4053 so I used one from a 780 I had laying around. My question is: is there a special casting number I should be looking for to keep it more on the original side? The carb is a 1969 if that matters. Thank you, Joe

Joe - Other than the part number 134-103 stamped on the 4053 front fuel bowl, I believe the only other item found on the fuel bowl would be the patent numbers (photo is from a CRG photo from a 1967 Holley carburetor):

Joe - My 1970 Mustang also has a Holley 4150 780 carburetor, which runs great, although it can be somewhat hard to start if I haven't driven it in awhile.
