But, I don't think that's the case at all.

ok so we tried again tonight. we bought a new o-ring but the gauge was thicker than the original so we tried the old o-ring again and of course it still leaked. and the the copper washers on the attaching union decided to leak. but thats an easy fix. could i possibly also be installing this wrong? do i take the o-ring off of the regulator and fit it in the space on the fuel rail before hand? and then once the ring is in i thread the regulator on? cause the fuel rail has a circular grove on the fuel rail around the threads where the regulator goes in. sorry i hope this is making sense. im kind of in a bind and im getting rides to work from family and im getting pressure to get a new FPR. i have a strong feeling im just missing something. can the nut on the FPR be in any position?

trying to research



so ill try the new o-ring. but what does it mean loosen up the nut and turn the regulator counter clockwise.

this is embarrassing that im having so much trouble with this

I think it means to loosen it so that you can rotate the pressure regulator independent of the lock nut position, allowing you to set it right and then torque the fpr down on the fuel rail.

Wow.... umm.... yeah. I'm sorry you're having so much trouble too. I'll dig out my spare fuel rail and FPR and make a video this weekend if need be... you are making this too hard or something is F@$%ED up.

No, you can't install the O-ring before the FPR. A thicker O-ring could cause problems if it is too thick. Get the right size... it'll be metric. 10mmID x 2mm is what I come up with measuring mine and accounting for changes in shape from prior service.


Step one: With FPR off of fuel rail unthread lock nut all the way with just your fingers (this means the lock nut will move UP toward the FPR's body).

Step two: screw FPR onto the fuel rail by hand until it stops... DO NOT TIGHTEN ANYTHING!

Step three: Unscrew the FPR just enough to get it pointing the right direction.

Step four: tighten lock nut.

NOTE: To help ensure that the o-ring isn't getting pinched you may wet it with a little soapy water before threading the FPR onto the rail.

You know, it may be embarrassing and frustrating, but you've done a shitload more than most newbies here would ever try... and you've done quite well.

Been a few days with any word?

When I took my my FPR off for the rebuild - I just put it back on with a new copper washer and no problem. Wonder if your model year is that much different then mine (90') Don't reacall an extra O' ring.

There's no copper washer for the lower junction... there's a steel washer which isn't removable and an o-ring under it. There wasn't any change to this over any of the years. If yours was different then it's not Denso or had been modified.
