Mystery fuel pressure regulator

Post by Alexander_Monday » Fri Jun 12, 2009 2:27 pm

This regulator was part of a Whipple 7.4L supercharger kit from the 90's.
Past experiance tells me that if Whipple does not see a possible sale, they have a very short memory.
There is not any writing on it.
It is steel.
The bottom appears to be the inlet.

Does anyone recognize what brand it might be, or have any information about it?
It is possible it was made just for the application.

Since it was for a TBI application, and fuel pressure is typically lower than MPI, I am not sure of the pressure range.

If I apply air pressure to the inlet and put a gauge on the outlet and a small hole to release pressure while I adjust it, will these readings reflect the pressure range it will have with fuel?

Why in the world would it have so many vacuum/boost ports?

Joe,
To tell you the truth, I am not sure. I have been devoting all my time to my new business and my VW stuff has been sitting since June, so there is a good chance I might. I will dig through everything this week and let you know.

After all these years to find support for this would be a miracle. Please see the top right of the page where it says Shoptalkfourms.com for the link asking for support for this site. They really need the money and your financial support.
