Review: ** The Right Holley Vacuum Secondary Diaphragm For 4150 Holley 80570/80670 Street Avenger ** - This Is The Right Holley Vacuum Secondary Diaphragm For 4150 Holley 80570 or 80670 Street Avengers. I called the Holley Tech Department to order a new Vacuum Secondary Diaphragm for my 17 year old 570 cfm Street Avenger. After being put on hold for 20 minutes when I called, I finally got a Tech to looked up the proper Secondary Diaphragm for my 80570 carburetor, and said it was Holley part # 135-4 that I needed. ** He said it was the proper one for the 4150 Holley 80670 Street Avenger too.** I have a 670 cfm Street Avenger also, so I ask for future reference. The Tech said they were out of stock and are back ordered when I called. I came here to desertcart and they had one in stock, so I got lucky here and got it installed the following day. The Tech was correct, so I also know now physically, it is the right size rubber diaphragm and the proper length shaft for the carburetor models listed above. The shaft length for the Holley # 135-4 is 2.054 inches. I hope this helps with cutting down on the 40 minutes with research for someone else, as I put in. I always research, so it cuts down with getting the wrong part when buying online. I hate that when the wrong part shows up !!!! P.S. - The new cork vacuum gasket is included with this Holley # 135-4 Vacuum Secondary Diaphragm, but "NO" new tiny C-Clip, at least mine came with a new cork vacuum gasket and no C-Clip. So take care of the C-Clip you remove when changing out your Vacuum Secondary Diaphragm, or you will have to locate a new very tiny one. Don't forget to replace the cork vacuum gasket, or you will more then likely end up with a vacuum leak, and your new Vacuum Secondary Diaphragm will not function, and other problems that occur from a vacuum leak in your intake system !!!!!

This was a perfect replacement. Kind of a nuisance to get it installed in the secondary, but patience is key. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/19350183-holley-135-4-vacuum-secondary-diaphragm](https://www.desertcart.uy/products/19350183-holley-135-4-vacuum-secondary-diaphragm) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-05-19*
