Questions & Answers

Is this compatible with the Holley 670cfm Street Advenger (4150)?

I'm not familiar with that carb, but I'm guessing all 4150 carbs have the same seat diameter. This hat will fit if you have a standard air cleaner gasket.

What is the correct ID for the 26040 cap? Is it correct that my air cleaner flange measures 4 7/8" and will not fit on it?

26043 is a 5-digit number. I'm not sure what 1/8" corresponds to.

Will it keep smoke inside for a leak test?

There isn't a very good seal.

Aside from ten dollars, what's the difference between the 43 and 44?

The ALL26044 has an o-ring machined into it. On the bottom, there is a ring.

Casting is very thick, and the machining is very nice

5/5

Casting is very thick, and the machining is very nice. I bought it to weld on tubing to make a blow through hat, and while it welded, it was some of the worst aluminum I've ever worked with. So I wouldn't buy it with the intention of fabricating something with it, but it's a fantastic carb cover.

It's not the best deal, but it gets the job done

3/5

I'm surprised at how much these basic plastic carburetor/EFI covers cost, given that they're just a piece of plastic. It's not particularly noteworthy, but it gets the job done. There is no wing nut or stud included (this isn't a flaw; it's just something to be aware of).

Coverage for the Holley 4160 is insufficient

3/5

Purchased to store a carburetor cap. This cap is just a smidgeon too small to cover a Holley 4160 in its entirety. Because the choke horn prevents it from properly seating, the cap is rendered useless for dust protection. To work properly on any Holley carburetor that has a choke, the cap would need to be slightly taller.

Last but not least, I'll need a quality cap for this project

5/5

It functions and fits properly. I'm glad I chose the Delux cap over the other one; it's heavier than plastic caps and, in my opinion, will last for the duration of my ownership. IMCA Stockcar. The rubber oring at the bottom adds a desired sealed effect.

My Holley carbs will not fit

3/5

Although the ALL26040 plastic carburetor hat appears to be well-made, it does not fit my Holley 4160 square bore and Holley 4175 spread bore (Q-1) carburetors. Carbs that can be used as a replacement for jet fuel. It becomes entangled in each of their choke towers. It does, however, correspond to my early-adolescent years. 1970's Q- I have a jet carb on hand as well as a new Demon "Street Demon" carb.

Holley 4175 is not compatible with this part

3/5

To get this cover to seat all the way on my Holley Carburetor, I'll have to grind the inside lip down.

Five out of five stars

5/5

Does exactly what it says it will.

It's likely that a component didn't fit

3/5

My order was lost, and I had to have it resent, and the second part will not fit my 4150 flang on my holly carburetor. It's not worth it to try to return a part for the $12 I paid for it.
