aeromotive regulator problems

3352 Views 4 Replies 4 Participants Last post by  Strictly Diesel
A couple of days ago I noticed that my truck was idling rougher than normal. I checked my aremotive fuel pressure regulator and the pressure was up around 100 psi! (Normally its 64 psi). Then I shut the truck down and the pressure stayed at about 40, and did not bleed down like it should. I then started it again and tried to adjust it back down from 100 and 70 psi was as low as it would go. Any ideas??

I have a similar issue with mine. The pressure doesn't bleed back down after shutting it off. I don't however have the high pressure problem. I spoke with Dennis about it and he said to remove the fuel inlet hose and the adapter, then clean it out and reassemble. I haven't done it yet but it makes sense to me.
