What should be the maximum capability of the stock D-Jet pressure regulator? Mine only goes to 36.
If that's normal, is there another similar-format regulator that can go up to around 45psi? Background: Microsquirt project. Was hoping to use the stock regulator, but now need something that I can easily mount in the same location, if possible. Injectors I'm using are rated at 43.5psi. Discuss! |

Quick update... per Summit Racing, MSD has discontinued the MSD-2220.
Rock Auto has the Delphi version, says it's 29psi. I tried two used ones from Chris; one only got to 34psi, the other had the locking nut stuck so I didn't force it. NAPA can get me a "FPR for the Porsche 914" but it's special-order only, and they don't know how adjustable it is. Rock Auto looks like the Delphi version as well, 29psi listed. I can't find a FPR for the car on Pelican's web site. I'm guessing that if I'm running more than 35-36 psi I'll have to go aftermarket on the FPR... |
