End of last season I started to get small but significant fuel pressure variations that I think were the fault of my adjustable fuel pressure regulator. Anybody else ever experienced this? There's not a lot inside of one of these things, so I'm trying to figure out what could be wrong with the thing.
The item in question is an Aeromotive, if that makes any difference. It's on a 1.6, and normally is set around 38 PSI. After quite a long time of just faithfully doing it's job, it has started to meander around thru the race day. Always goes higher than desired (to a max about 48 or so), but it isn't consistent - FP goes up then comes back to normal like it's got a mind of it's own. Any thoughts? Should I rebuild or just chuck the regulator and buy a new one?
Thanks in advance for an help that is offered.
