On Holley's website you will find a chart with part numbers for each gasket set. Using the number on your Holley you can locate the proper parts.

In most modern-day fuels ethanol is found in most of the parts in the kit. Are these parts resistant to it?

There is a green accelerator pump made for racing fuel containing alcohol. On my old Ford truck, which is my daily driver, I have used a 4412 Holley engine for the last 48 years, and it usually needs to be rebuilt every 9 years or so. There has not been a failure.

Selected User Reviews For Holley - 37-474 Carb Repair Kit

The impression I got was not good

3/5

Although the kit contains everything I needed, the instructions are illegible. It's like reading a bad copy of a bad copy, it's impossible to figure out what to do. As a result of the packaging, the gaskets were bent in many directions. It came packaged in a flimsy paper box inside a Tyvek envelope.

I am very pleased with the service and the product

5/5

It was easy to follow the instructions because they were clear and legible. I completed the rebuild in less than two hours (I spent longer figuring out which kit to buy). The truck runs great, and the only parts I forgot to purchase were a new fuel filter and spring, but I was not at.

I was not able to use all of the parts with my Holley carburetor.

This program runs well and is very easy to use

5/5

I believe it had parts for all varieties of this carb My engine has a Holley dual pump and choke with dual feed and dual pump. The maximum number of four seems to be too much. In order to replace the 3 vortec auto with a Quadrajet, we will need to swap the Mazda pup with the Vortec oil burner. This means that it is for sale! Basically, these instructions are for rebuilding a carburetor, but I have rebuilt more than one since 1966, so take that with a grain of salt, depending on your experience and/or the help available to you.
