Well... normally I'd tell someone to use a butane or propane torch to heat the outter coupling so that it will expand and fee up, but since this is a fuel line... well, that probably wouldn't be the smartest move to make. :-)
You might try spraying some Liquid Wrench on the couplings and let it soak for several hours. Don't bother with WD40, that stuff works marginally in that form. Use something like Liquid Wrench, it works far better.
If that doesn't work, you can cut the metal fuel line. YOu'll have to rent a doulbe-flaring tool from AutoZone (or equivalent) and then put a segment line in it's place when you go to replace the fuel filter.
Without seeing it, I don't know of any other ideas that come to mind.

| A chuck of dry ice pressed hard against the nut on tubing for a few seconds might due the trick. It should shrink it and crack the rusts hold on it. Use ice for several seconds and then quickly try a wrench on it to break it loose. |

| would a engine diagnostic test show that the fuel pump is bad or how would they determine that it was the fuel pump and could it have been the fuel filter instead of the fuel pump the whole time. |

Great idea... since dry ice is hard to come by, you know what else may work?
Try using a can of pressured air (the stuff that you use to clean your keyboard with) and turn it upside down when you spray it. It comes out insanely cold and will likely do the trick too.
Plus, after your done, you can get your friends to blow the canned air in your face, allowing your hair to flow about sensuously. Have your other buddy take some photos while they say "work it... work it baby!".

| Actually Dry Ice is not as hard to come by as you think. A few phone calls should find some and you might even get some free stuff for a big ice cream shop that sells hard serve ice cream as usually their shipments come packed in dry ice if it is shipped any distance. Heck here I can even buy dry ice at a big grocery store. |

You would do a fuel pressure check. BTW, if you are one to run tank low a lot, those pumps can have a shorter lifespan. |

| yeah I run the tank low alot but what i can't figure out is they said it was the fuel pump, I got it replaced and I have the same problem as before They asked me if I wanted the fuel filter changed and I said no. |

| Filter should be changed every 50 to 100 K miles depending on gas quality. A few dirty tanks of gas can wipe on out though quickly. BTW, I would have changed filter before pump if I was having problems unless pump flat out quit and I would change it with a new pump. |

BTW, the diag cannot tell if pump is really bad, only a fuel flow and pressure test with a good filter can tell you that. |

| ok I put the fuel filter in, same problem so I took it to autozone and they did the handheld computer test this is what it said. the pcm has determined that the voltage signal from the pressure sensor in the evaporative emission control system is too low for the current engine operating conditions. Fuel tank pressure sensor now can you tell me where the fuel pressure sensor is located on my truck. the code was P0452 |

| That sensor should be on canister not tank. You might try replacing fuel cap on tank. |

| The canister that should be under hood. Do check/replace fuel cap as it has been known to cause this problem. |

ok.. i kinda got the similar problem...
things with the fuel part of my truk keep going bad...
i got my fuel pump switched out February of this year and again about a month ago...
then.. my crank sensor...
now...
something about the canister purge solenoid or the fuel tank pressure sensor...
i went to auto zone and this is the reading i got....
EVAP system flow during non purge condition explanation
The ECM has detected vacuum flow to the fuel tank pressure sensor during a system sealed condition..
Probable Causes
1. Failed canister purge solenoid
2. Failed fuel tank pressure sensor..
ok.. so what does that mean and what do i gotta do? |
