Usually, just runs really lean for a couple of minutes, and will not go above idle until fresh fuel finally clears through. Reviewed in the United States on June 20, 2021. Pre-set at 2.8 PSI The fuel pump and fuel line setting top center of the engine was not only in the hottest ambient temp, except for the exhaust manifolds, under the hood they acted as a heat sink transferring heat from the block to the air. Prewar cars have very low compression and will run better on gas that has some kerosene added. . I installed this on my Onan 7000 generator as part of a project to resolve vapor lock issues in hot weather and high altitudes. Loosening the regulator locknut and turning the adjustment screw clockwise increases the pressure. To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area and wear gloves or wash your hands frequently when servicing your vehicle. Sorry, we were unable to perform your search at this time. The ethyl acetate in the IMCT loosens hydrogen bonds on the gasoline making it easier to light to burn, but the "oil" - heavier hydro-carbon nature keeps the vapor point higher and flash point still low enough to give good performance. On the Holley 12-804 fuel pressure regulator, the factory preset is supposed to be 2.8 pounds - can anyone say is Holley usually pretty accurate on these presets? The fuel pressure is at 1 - 3 psig since the pump is not running. Discussion in 'The Hokey Ass Message Board' started by oldrelics, Oct 12, 2010. 12-804 12-500 Low-Pressure Fuel Regulator (std. I've had some luck using LeadMax2000 but it's not a 100% cure. The other possibility is that it is due to the higher pump pressure. I can only say acetone will lower flash point (light easier) but also lower auto-ignition temperature and thus create knock into too much of a quantity - while a very little bit will raise octane but not lower auto-ignition - so if you go TOO low with kerosene or diesel you can bring back some kick to the fuel with SMALL amounts of acetone. Posts: 32372. 9517377223. NPT Inlet Attachment: #2. If you put in too much you can return the fuel to some "kick" without knock with a small amount of acetone. A vapor lock condition would be caused. MFG. Could you explain a little more about how you would run the bypass? The thinner, lighter products are at the light end of the scale the thicker heavier products are at heavy end. [endif]-->,
