Has anyone successfully R&R the little "J" fuel line in situ?

[markmalin]

I have the right intake manifold off. The big "T" fuel line and the one between the fuel rails out, but I'm really struggling to get the small "J" shaped fuel line off the back of the pressure regulator on the back of the left intake manifold. Has anyone successfully been able to remove and replace this with the engine in? I can get a stubby 15mm wrench on the pressure regulator side to hold it, and have a clawfoot 17mm socket I can get on the fuel line...and as I understand this, I need to loosen the fuel line counter clockwise (normal threads), but I can't get it to budge without the whole thing moving. I'm tempted to leave it and just replace that short line if I ever take the engine out, but I'm so close... That said, if I get it off, will I be able to tighten the new one sufficiently??

Anyhow, if anyone's had good success getting this off, let me know how you did it.

Thanks
Mark

Mark,

Were you referring to the fuel hose connected to the bottom of the Carrera 3.2 FPR? See picture below:

Pretty sure I took the regulator out to replace the hose on my '88. Wasn't that much of a problem.

Yes, that's the one. I wasn't sure I could remove the regulator without taking the manifold off. So can I pull the regulator off as a unit like in the picture? That would sure make it easier to work with

Mark,

Search for my post regarding my Carrera 3.2 FPR saga. I failed miserably in my attempts to get off the FPR and sought help in the forum. Even the well experienced guys stated that it was not easy to remove it with the motor installed and I agreed with them. There are many ways people did it including removing the fuel rail. But by some strange coincidence, I found a trick to get the FPR without making any special tools or removal of the fuel rail as suggested by many. People were doing it all wrong!

I have some pictures in my post showing how I did the removal. It was easy and effortless. You need to disconnect the J curved fuel hose from the main delivery line and proceed loosening the bracket holder. Then pull the assembly up for the removal of the other connection. And you are done.

Thanks, Tony. I found your thread. I actually read through it a few days ago but wasn't at this point so I wasn't paying attention to the FPR steps.

So you disconnected the fuel line that the "J" piece is attached to (not the J's coupler where it attaches to the regulator, and disconnected the coupler between the regulator and the fuel rail, correct? I can probably do this and just pull the whole bracket and regulator assembly out because the other fuel lines are already disconnected.

Mark,

The "J" hose can be replaced without removing engine OR removing intake. I successfully did this (engine bay fuel lines replacement) last year.

How I did it: I removed all the ancillary components above OR in front of the intake - i.e. Airbox, AFM, heater pipe/fan (cruise control should be fine as is). Once you remove all these (PITA), then you sorta have access to the "T" hose connectors and the "J" hose as well as the cross hose that goes between the regulator and dampener.

Replace all 3 hoses (I got mine from Griffiths). Only once you've removed them all, do you really notice the micro cracks (like in the 'pit' of the J-bend). It was a tough job, but doable with patience and time. Crowsfoot (I think 17mm and 19mm) helps you wiggle into cramped areas. Stubby open end wrenches would also be good here.

You can do it!

I'm sure it can be done, but my question is how old are the intake gaskets under the left manifold? It would seem to me that if you are this far in and already have the right intake manifold out, Now is probably the best time to replace the left intake gaskets as well.
