I was going back and forth between your pics and ones I took today. It makes sense now. Yes, that restrictor is in place. I have a regulator but was going to chase down a cause of high fuel pressure. I think I’ve found it now. Thank you for sharing your knowledge and experience.
Yup if you have that restrictor in place on that 5/16" side that will spike the pressure. Drill that out, put a slit or drill a hole in the top of that 1/4" like I did, and hook it all back up. See how it runs then.

That sh*t should be in a tech/knowledge based post. I'm sure this won't be the last time this happens to someone.

I was so excited to get this going I go up at 5 this morning and dropped the tank in my driveway. All complete and running great, 58 psi of fuel pressure with engine running and vacuum line from the regulator removed. Again, thank you so much. I know you saved me a lot of headache.

58psi is on point, what vac line did you remove?

Which is in this post here..


But yea, could probably make a post with it.

I referenced your build thread a lot when planning and executing. Somehow I missed the whole sender thing so I really appreciate you sharing again.

No problem.
The one on the regulator on the manifold. And drove around a bunch today and no fuel coming out of the vent tube. I didn’t have anything to make a slot so I drilled an 1/8” hole.
I'd hook it back up.
