On this 2023 July 4th weekend, bowtie6 got treated to a new fuel pressure regulator and braided lines. The old setup consisted of a GM style non-adjustable pressure regulator and a set of E85 resistant rubber fuel lines – I wrote an article about that (click here). I was never really pleased with the rubber hoses because the braided lines are much nicer and bullet proof. So I pulled the trigger and ordered parts for the new setup.
This is what the old setup looked like:
The new regulator is a high pressure version from Aeromotive with a matching fluid filled gauge. This is the setup after the first fitment. However, with all this bling that bracket just did not look good…And this is what I mean…
We had to cut the old mount and in the process the aluminum mount got scratched up pretty bad. I tried to sand this down but didn’t make much progress. Instead, why not just use some carpet material?
Ah! Much better! A keen eye will also notice the difference in pressure. I checked what the E67 PCM expected, and that was 58 lbs/in, so I bumped that up a bit.
The photo above, shows the whole setup.
- On the left the box with the silver lid holds the high pressure fuel pump
- The line going up from the pump goes into the regulator and from there is a return line back to the pump container and to the left the line going to the engine. That is a hard stainless line that goes under the body to the engine compartment.
- And finally the lines that feed the pump container.
I’ve written about this setup in a prior post Ecotec Fuel System and ECOTEC Fuel System – Part 2 in case you want to read more about that.
And this is what the front looks like. This is another braided line going into the fuel rail. The other side connects to the stainless tubing under the frame of the car…
