How do you check fuel pressure on a ls1?

Well you can check if you have pressure by taking the cap off of the fuel rail on the drivers side rail. Looks like the cap on a bike valve stem, works the same way too. If you dont hear your pump when you turn your key then theres something wrong somwhere.

What should the fuel pressure be on a LS engine?

The old system only needed a paltry 8 to 10 psi at the carburetor while an LS engine with an Efineeds a constant 58 psi at the fuel rail. This means that it’s a necessity to upgrade your fuel system with an electric pump and a fuel pressure regulator.

How do you change the fuel pump on a Camaro?

First, pull the fuel pump fuse and disconnect the negative (black) battery terminal. Also, bleed the fuel pressure at the Schrader valve on the driver’s side fuel rail. Make sure you have a bucket and rags ready for this. Lastly, open the gas cap to relieve any more pressure. Now, you can proceed to cut the trap door as shown in Figure 3.

What kind of regulator do I need for LS engine?

If you’re installing an LS with a return fuel line system, a regulator is installed between the fuel rail and tank to provide consistent fuel pressure. Then hoses must be run to a 3/8-inch supply fitting and 5/16-inch return fitting on the fuel rails.
