![]() With their MIL SPEC hard anodizing it helps the hose end last much longer over traditional Brite-Dipped ends in extreme environments, such as salt water marine applications and cars running corrosive fuels, like alcohol.” “The Auto-Crimp hose ends can be used anywhere the Pro-Lite 350 hose can be used. It is easy to assemble, has low abrasion, with great flexibility.” Kevin Cochran, Sales and Product Manager at Earl’s tells us, “The Pro-Lite 350 hose can be used with Fuel, Oil, Water and Air, and is designed to be used in medium pressure (350PSI) and medium heat (300F) environments. The Auto-Crimp fittings are really easy to put together, and combined with the nylon braided Pro-Lite 350 hose, are a great way to save a decent bit of weight. On the fittings end of things we went with Earl’s Ano-Tuff Auto-Crimp hose ends, which are designed to live up to their name in harsh conditions and offer a bit of weight savings as well. Originally, we were going to use braided stainless lines and standard reusable threaded AN fittings, but since this project is going to be a dedicated drag car, we wanted to save as much weight as possible anywhere we could, and Earl’s had just what we needed.Įarl’s Pro-Lite 350 nylon braided hose offers the same benefits as using a stainless braided hose, but weighs only about half of what an equivalent braided stainless hose does. To tie everything together, and carry the fuel to feed our 800 horsepower fire we looked to the experts at Earl’s Performance Plumbing. We went with MagnaFuel's MP-9833 two port regulator for high horsepower N/A carb'ed applications. Since we needed to bring down the fuel pressure about 20 psi before it makes it to the carb, we needed a dead-solid fuel pressure regulator. ![]() This regulator should be just what we need to keep steady and reliable fuel pressure on our carbed LSX. And since we will be going straight N/A, our MP-9833 doesn’t have 1:1 boost referencing. The MP-9833 is a large two port design that can be adjusted from 4 to 12 PSI, and support engines producing in excess of 1,600 horsepower. To bring down the 25 plus PSI the QuickStar 300 produces down to a useable level with our carburetor, we also picked up one of Magnafuel’s Hi-Flo regulators for carb applications ( part number MP-9833). You just have to keep the line from the tank to the pump to a length of 3 feet or shorter.” For example, if you need to use a stock type tank, mounted below your trunk floor, and you want to put the pump in the trunk, you’re going to have to be able to pull fuel up, and the Quickstar can do that. ![]() ![]() Gravity fed is still always best, and is better for the pump, but in some cars you don’t have as much flexibility in where you can mount the pump. So the Quickstar can be mounted as high as 12 inches above the liquid level, since it doesn’t absolutely have to be gravity fed. Ward continues, “The Quickstar needs to be mounted close to the fuel cell or tank because they are a pusher type pump, but it still has an incredible amount of suction. The returned fuel leaves the pump and is sent right back to the tank.” Ward tells us, “On Magnafuel’s fuel pumps for carburetors, there are fuel by-passes built right into the pump, meaning you can use a dead-head type regulator, saving you from having to run two lines the full length of the car. You also can get the Quickstar fuel pumps with or without a built in pre-filter, which has a cleanable element that can be taken out, cleaned and reinstalled, so there’s no need to search for a replacement element when it needs cleaned.” Ward explains.Īs many of you may already know, it’s always best to use a return style fuel system, regardless of whether or not you are using a carburetor or EFI. ![]() A cool feature is that the fuel pressure the pump produces can be adjusted from 25 to 36 PSI to help with fine tuning. “The Quickstar 300 is rated from 950 to 1,000 horsepower on gasoline, and you can run it continuously for up to an hour and a half. To get more info on the QuickStar 300, we called up Rob Ward, Tech Expert at MagnaFuel. The black line running straight up is the fuel return line, which makes installation much easier since we don't have to run two lines the full length of the car. The silver canister on the suction side of the assembly is the built-in pre-filter. Here's the QuickStar 300 mounted in the trunk. ![]()
