Curious if there is a way to rebuild FPR and Damper

[FA-18C]

Just curious is anyone has managed to take a 3.2 FPR or Damper apart and figure a way to restore full functionality once they have crapped out? Clearly on both of mine, they were leaking, thus the replacement. But the housings are both clean and in good shape, so wondering if anyone has figured a way to repair these?

We've wondered the same thing. No luck so far.

We did find these guys who are manufacturing their own with Bosch components. I have one on the table for a 951 rebuild we're working on. Looks great, but not original.

I do like the idea of the Bosch replacement regulator in a machined body, but keep in mind if you are tying to use the factory mapping the lowest pressure available in this regulator is 3.0 BAR which is ~44psi. the factory 911 regulator is 2.5 BAR, so the unit you have will push more fuel.

Also on these dampers the original would have had much higher volume. The drop in cartridge dampers are designed for sequential fire injection not the batch fire our cars came with. to meet the requirements of our batch fire system the dampers should really have more volume or more dampers.

Coincidentally there is a company specializing in 928s that make a rebuildable FPR and Damper explicitly for the 2.5 BAR and batch fire systems as the 85-86 928 use the exact same regulator and damper as the 3.2 Carrera.

Thanks for the info, I sent each of them an inquiry regarding the volume.

Adapt does show this on their regulator page

2.0 to 5.0 adjustable fuel pressure regulator

This kit must use the adjustable fuel pressure regulator as Bosch does not produce a standard 2.5bar pressure regulator in this form.
