The holley rail looks nice and has a provision for a fuel gauge, but I noticed there are cheaper off-brand alternatives. ### ⭐ DO NOT BUY HOLLEY PARTS FROM AMAZON! *by T***E on May 30, 2014* I received what was believed to a new Holley Carburetor that I paid full price for was a faulty carb. Amazon is known to be bad for performance parts and I will explain. My bowl came damaged and bent beyond recondition, I was forced to purchase a new bowl to fix the float problem, I was overfilling my bowl and couldn't idle. When I purchased the new float at a local performance shop he (Eddie) explained he has heard of this problem multiple times.He explained to me that when folks order holley parts and such from summit racing and jegs and other performance websites, the returned items and damaged parts are returned and then sent to amazon to sell for a better price and is stocked into amazon's inventory. This completely explained my situation. I have pictures of a float that is copper and suppose to be new in the package and was actually damaged and a complete nightmare. Bottom line, buy your performance parts from the manufacture or from a legitimate performance site. ### ⭐⭐⭐⭐⭐ Holley *by S***2 on April 25, 2021* Works good right out of the box ## Frequently Bought Together - Holley 0-4777C 650 CFM Double Pumper Carburetor - Ryanstar Throttle Cable Bracket 4150 4160 Series Throttle Brackets Billet Adjustable Aluminum Black - SENCTRL 0-15 Psi Fuel Pressure Gauge, 1-1/2" Dial Size, 1/8" NPT Lower Mount, Silicone Oil Liquid Filled, Stainless Steel Case, Inline Low Pressure Gauge, for Water Oil Air Pressure Test --- ## 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.kg/products/21831801-holley-0-4777c-650-cfm-double-pumper-carburetor](https://www.desertcart.kg/products/21831801-holley-0-4777c-650-cfm-double-pumper-carburetor) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-06*
