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 Amazon 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 !!!!! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Just replace yours now *by T***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on June 1, 2022* If your cleaning the carb or taking it apart to fix somthing just replace this part. Its already ok the bench. Otherwise you wont have any secondaries ok the road. Or buy one and thrown it in the glovebox as a backup ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Aok *by S***1 on Reviewed in the United States πŸ‡ΊπŸ‡Έ on November 30, 2018* Easy install. Make sure to pull the ball bearing and clean out the port. Mine was crammed full of something like resin. The ball couldnt even move. Carb and choke cleaner wouldn’t cut it either. Had to dig it out... believe it or not my vacuum secondaries work now. :) --- ## 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.dk/products/19350183-holley-135-4-vacuum-secondary-diaphragm](https://www.desertcart.dk/products/19350183-holley-135-4-vacuum-secondary-diaphragm) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-26*
