How Much Fuel Pressure Does A Ls3 Need at Ann Swarts blog

How Much Fuel Pressure Does A Ls3 Need. What you should do is take a look at gph rating of the pressure the carb needs, like around 6 psi. Most of the ls3 guys are reporting the stock pump maintaining about 60psig. There is no way to adjust this but that is what the ls3 runs on. Its on the edge of excessive but without seeing pump duty cycle. I have an ls2 and am. Most will loose a couple. Ls fuel pressure too high. It is internally regulated for around 60psi fuel pressure. In my ls swap i have a 400lph fuel pump in my tank with a c5 return style fuel filter/regulator and 3/8 inch fuel lines going to the fuel rail. The lower pressure walbro pumps bypass at 50 psi, and the high pressure pumps bypass at 100 psi, from what i've found. For instance, an 8an feed line and 6an return line on a 1000 horsepower gasoline or race gas powered ls with 30psi is sufficient. The high fuel pressure adds to the load on the pump which can cause it to have a shorter life span. This is the same as the ls2. However, on an e85 combo, we recommend a 10an. It loosing 8 psi isn't a huge deal.
