Hello im looking for a better picture or more detailed diagram of the fuel line system primarily the part under the uim i have tried searching and this is the best i can find. The main thing i need to know is where the 3 fuel lines plug into the rats nest. I also want to double check that it is suppose to be a 5/16th hose?

In the picture, just to the right of the catch tank it shows the three lines where they get larger in a section is where is where the hoses are. This is where they hook into the hard piping. It's not really all the way under the UIM. It is more under the TB elbow pipe.

These hoses fit really tightly. It may be that the O.E. are 9/32 or a metric size. But I have heard of recommendations using 5/16, like the Banzai racing fuel pulsation damper elimination.

Recently worked on this area of my car. Since mine were in good shape I just left them and didn't deal with the sizing issue, but my car is < 50k miles. Most cars will need replacement at this point.

If you search under "FPD" or "fuel pulsation damper" you might find some pictures of this area.

ill give it a try thanks man. and the part im confused about is back by the pulsation damper and pressure regulator

this helps a little but what about the air line or whatever the 3 line is

3rd line is the vapor line. It runs from intake to purge control solenoid to catch tank through the 3rd hard line (in the set of three in the nest) to the charcoal canister.

The diagram you posted is not totally the stock setup. Stock the pressure regulator is mounted onto the end of the secondary fuel rail, the return line that goes back to the fuel tank attaches to this. A fuel hose goes from the pressure regulator (I think, to a hard pipe and then to another hose) to another hard pipe (this is one in the set of three) and then to another hose back toward the fuel tank. The other hard pipe in the set of three is the actual fuel feed line. From this hard pipe there is a hose going from it to the fuel pulsation damper unit on the primary fuel rail.

FPD is mounted on the primary rail.
