testing fuel rail and injectors for Jeff l28 et. will install on engine next and give it a test run. After that i will build a wire harness using a 1988 300zx z31 turbo harness as a donor.
Cool! Pallnet Fuel rail. Those injectors have 4 little holes in each tip. The pintle cap hole is big enough for all 4 holes as they are super close together.
ah so that is why I see the 4 pattern. Going to install now, and will get the new harness on the table ready to remove the covering. I am planning on leaving the PR intact so it can up the fuel pressure on a hot restart, not really needed, but easy to add so you have the option of using it.
having some leak issues around the injectors (air leaks) where they plug into the head. VERY critical on exactly how the stab in, I tiny deviation in angle (due to the rail mounts) results in air leaks. I think the best approach would be to use the reg injector mounts to either hold the rail (like a large u shaped piece maybe 3 across).
You always have such great test bench setups. Thanks for the demo.

or just mount to the head with the reg holders. Have you read anywhere else about vacuum leaks using the rail?
Hey Dave, great videos! you ever repair 280z for other folks? I’m in Florida and have a 1976 that isn’t running. Thanks!
not really, best thing would be for you to make a video of the issue.
