2Piece FPR O-Rings...

[Frank]

What is the best method for finding a replacement for the o-ring? Is it just a standard size that I can go to the parts store for? Thanks!

It's a fuel injector o-ring homie;)

Agreed :thumb: I sliced the one on my SL and noticed it was the same as the injectors.

[Frank]

Sweet folks! Mine have always been remote mounted. I will get that fixed tonight. it is seeping.

[Pat]

Must have been the moron that installed it..... :-)

[Frank]

Nope. Fuel rail is leaking at the flange for the AFPR. Now to find a new one.

Wow, that sucks. Good thing it didn't cause a fire :yuck:

Ya that would be bad! I quit driving it because it went quickly from a faint fuel smell every so often to strong. PARK!

If one is cracked might not be bad to check all your o-rings... 20 year old o-rings crack with age :( NAPA and other parts stores sell them if you don't have enough spares.

No, the rail is cracked, not the o-ring. When I apply power to the rail, fuel comes out of where the flange and the rail connect.

How do you apply power to the rail? Wouldn't that be dangerous?:confused:;)

[BadAssPerformance]

Doh! I missed that.

By 'flange' you mean the bung or the bracket that the regulator mounts to? I've had issues with the bracket leaking on the rail OD, almost impossible to weld easily. :(

LOL. I meant power to the fuel pump via the coil.

Its where the bung meets the rail.

pull it out and solder it up. OR take it somewhere and have it tig welded.

I don't trust many around here with a tig welder. I am not to keen on soldering it up.

I may through a FWDP rail on there since theirs accepts the stock style regulator. I don't know.

[Pat]

That's odd...that rail has not been touched in about a year when I installed the reg and injectors. I'd probably go with an aftermarket rail just to avoid issues in the future and have the stock rail repaired.

[Frank]

Ya I am still deciding. I don't actually have the aftermarket rail... I was thinking about buying it. However I guess if I can find some baizing rods tomorrow, I may go for it.

[Frank]

So what is the best solder type to fix this thing?

[BadAssPerformance]

I would guess silver solder like for sweating copper pipes? stainless steel rod works ok ;)

[slasky]

Its where the bung meets the rail.

So you need TP for your bung hole????

[Frank]

Well if the repair was for one of the injector openings, I think it would have been cake. However... there is no good way to get in at a good angle to repair the flange/opening for the fuel pressure regulator port. So I ordered a fuel today and it should be here tomorrow. I am stoked to get the car running again as I already mis driving it... only been 4 days! ;)

All in all, it is no wonder these rails eventually leak.... shoty design and assembly.

Huh, huh, you said "Bung"

Are you using solder? Ever sweat pipes? You just torch the metal around the crack (not the crack, but near it) and feed the solder into the crack, the heat melts and draws it in. So if you can heat the bung and bend the solder it can get there.

Yep. Know how to sweat pipes....

That is what I was going to do, however I only see it leaking again. I think there maybe a slight abnormality with this rail. I think there is considerable less mounting surface for me to draw the solder in and seal it. Hard to explain, but it looks no where near as secure as the injector flanges. Plus I already ordered the other rail.

If you already got another rail, dont even F with this one or ever bolt it back on the car.

...but for practice, did you wire brush the coating off it? and use flux? ;)

We.. that is the part of the problem. The bracket that you mount the fuel pressure regulator two gets in the way and you can't get any kind of brush down into the grove to clean it up. Unlike the injector flanges, the FPR flange is not completely flush up against the rail.

Sounds like you got yourself a nice conversation piece for the coffee table there :thumb:
