${cardName} unavailable for quantities greater than ${maxQuantity}. December - February gas mixture begins to vaporize at 11-15psi at 105 deg F, April gasoline is 9-11.5 psi at 124 deg F. If you had winter gasoline in your Antique car on a 100 deg day you would only be about 5 degrees from vapor bubbles in the fuel. Typically there are "winter" and "summer" blends with different vapor pressures to promote atomization at cold temps and to discourage vapor lock at hot temps. Bobburns thank you for the confirmation and technical explanation. US $57.76 Finish:Gold Zinc billet aluminum bracket that conveniently mounts a 12-803 Black anodized 12-804 or 12-803BP fuel pressure regulator utilizing the passenger side carb studs on any 4150 / 4160 style carburetor. You set it to the exact fuel pressure you want. Part #: 12-807. .

ESPECIALLY a 10% ethanol blend - once generically called the gasohol summer blend in that vapor system would really be a problem. What Rusty writes IS correct. My plan was to install a fuel pressure regulator on the line going to the generator so that the bypass valve needs less fine tuning to maintain the same pressure in all temperatures. Is it a product that would be sold by a panel beater's supply shop? This part is legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles. Show details It is a measure, as I understand it, of how readily the fuel will evaporate in open air. %PDF-1.4 I've had some luck using LeadMax2000 but it's not a 100% cure. Regards, Mike. I appreciate it!! Steve, gasoline isn't a single chemical compound but a mixture of hundreds of individual chemical compounds which have a large range of boiling points. Auto Parts v 6c02f45cd (2fvgn) cv1440. wrapped around the fuel lines. => https://www.holley.com/data/Products/Technical/199R7914-3rev3.pdf. ***The inlet pressure limitation is 7 psi. Refineries have been doing this for decades. Holley fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburetor. In a deadhead design the fuel comes into the regulator from the bottom past a check ball which is held open by a pin on the diaphragm. BP cannot by law tell you what you can blend into fuel to change its properties - but any petroleum distillate can be used - and the ester family - many of the alcohols we call them - can also be used. Some Holley 12-803 4.5-9 psi and 12-804 1-4 psi regulators mislabeled from factory. Most regulators need to be flowing to set pressure. Brands like MSD, Flowmaster, Hurst, Accel and many more make up the offering of enthusiast-driven products to deliver robust, complete performance solutions for builders, racers, and drivers. I will be trying one of these but am curious what is the active ingredient(s). Is there a brand name? . Holley(R) has been the undisputed leader in fuel systems for over 100 years. 3/8 pipe thread ports; 7/32 restriction; . The carburettor was flooding, the electric pump was still running. Tags: None TheSilverBuick ALMOST Spidey ! "Pure" Ethyl Acetate could be called an "alcohol" as Ethyl acetate is the ester of ethanol and acetic acid; and it is manufactured on a large scale for use as a solvent. Refining of oil is basically heating it into vapors and then capturing those vapors various degrees of cooling - at the top is "propane" - at the bottom is "pitch" or "road or roof tar". Yes, you will need to buy the type of connection you want to use such as hose barb, compre. Check the status of your Sorry, we were unable to perform your search at this time.
