Fuel Injector o-rings

I have a 2000 rodeo with the 3.2L and will be replaceing the intake manifold gasket due to a leak. It was also mentioned to replace the o-rings on the fuel injectors as well and the fule pressure regulator hose. Has anybody done this and if so how did it go?
Was it a pain in the arse or did it go smoothly? Anything I should look out for?
I have been looking in the service book and all I can find is the fuel pressure regulator. there is no mention of the hose....
Thoughts or comments would be greatly appreciated.
Thanks

It can be a bit of a hassle to gain enough clearance to get the intake off. The trickiest part is getting the fuel hoses unclamped and off the hard line and another thing is that the fuel lines bolt to the back of the intake with two 10 mm bolts that you can't see. Once you get the intake off, replacing the injector o-rings is a breeze.

I would recommend removing the top half of your fan shroud before beginning this job. I broke mine while prying around trying to get enough clearance to get the old gaskets out. New shroud was $60-65 from St. Charles.

I wound up taking the injectors and fuel lines out of the common chamber and removing the common chamber to have enough clearance. I probably should have replaced the o-rings when I put it back together. I did not disconnect the hoses from the metal lines because I couldn't get to the hose clamps. And, as has been mentioned, I couldn't see the bolts holding the lines to the back of the manifold.

It almost makes you think the engineers that designed the manifold didn't really give much thought to how to repair it without removing the engine from the truck...

Engineers don't care about practicality when it comes to designing vehicles, as long as it fits together and looks good. I think Dodge has a car where the rear bench has to be removed to get to the battery (like in the old beetles, my cousin's old bug would shock you if she hit a big enough bump)

Part of becoming an engineer should require working on and maintaining the product (vehicle) you just build for at least a year.

It didn't go to bad with the exception of removing the fuel lines. I ended up breaking one of then trying to pull it off. I was able to get the entire manifold off with the fuel rails in one piece and once I had it on the bench, cleaning and replacing the gaskets and o-rings was a breaze. The only headache putting it all back togather was those darn fuel line bellow the engine, they give you barley enough room to get the lines off and on and you are battling the exhaust pipe with the O2 sensor in your way....
--I did have a bit of carbon and oil in the intake... is this normal or should I be worried??

When I did mine, it had some carbon stuck in it also. Had about 70K on it at the time, and I don't drive it very rough, but did start running 93 octane gas since then
