I have a fuel leak in the rubber fuel line that connects ath front and rear fuel rails on my 1990 Maxima. From what I read here this is a common problem and shows up when cold.
Is it possible to replace this line without removing the intake plenum and manifold?
If I have to remove the intake plenum and/or manifold what is involved in time and parts (gaskets etc?)
Thanks,

manifold must be removed.
it's take a couple of hours.

parts you'll need:
new hoses (forgot what size- call a dealer)
intake collector to throttle body gasket
throttle body to intake manifold gasket
upper and lower intake manifold gaskets.

that'll run you about $40 for the parts.


You'll also need a few metric allen wrenches to get everything off. also recommend buying a can of liquid wrench or penetrating oil of some sort if you don't already have some.

 

Thanks!
Does the manifold split with the intake plenum seperating from the manifold or does the manifole have to come off the block?

here's some pics to answer your questions...

I left the lower manifold on the car, but you'll also have to remove it to change the fuel lines.

THANK YOU Mat.
A picture is definatly worth a thousand words!
Now I see exactly what I am up against. It looks pretty straight forward, as long as I have the gaskets it should be pretty easy.
Nice manifold, it came out reall good.

Thanks

yeah, it's pretty straightforward.. just getting those allen bolts loose will be a bear. I had to stick the allen wrench in the hole, then grab it with a crescent wrench and tweak on it unti lthey popped loose. the best thing to do is use the actual sockets with allen heads that you stick on your ratchet. I don't have any though, so I used what worked.
