my truck is a 4.6 4x4 f150 and i have 80,00 miles and need to change fuel filter. DO i need to bleed fuel pressure or can i just unclip the line from the filter? Also should i go ahead and buy new shocks on the front the are the same ones from when the truck was made.

 

No, you just unclip the lines and replace the filter. I like to spray a tad bit of penetrating oil in the clips and twist the filter around a time or two to losen up any crap in there. I do advise wearing safety goggles for obvious reasons.

As for the shocks, I changed mine out at 160K. Probably a few years and a few sets of tires too late. I notice that my tires are not wearing out as fast on the front. So, it wouldn't be a bad idea to keep up with a good set of shocks on your truck.

Good Luck!

 

alright sounds good thanks!

 

You do know that it requires a special tool to change the filter, don't you?

 

I did a search on the subject. there are many threads such as this one.

If you haven't changed out one, you would benefit from doing a search and reading up on it. It is a very easy job, but must be done correctly so as to not break the clips. The penetrating oil is a good idea, as long as that has been on there. A lot of us change them at 15,000 miles.

 

haha no i didint know that. I was just about to ask why the lines wont disconnect thanks!

 

Yeh, you'll want to use the tool. I know some guys have done it without it but it is much easier with it IMO. $5 at any autoparts store.

 

Did I miss something? Or did he ask whether he should relieve the pressure from the lines, someone said "nope, no need to," and everyone agreed? I'm not an expert here, but I think bleeding the lines, through the schrader valve at a minimum, is not only a good idea, you'd be silly not to do it. Some folks here have allowed their truck to sit overnight, or sit for awhile with the gas cap off, and that apparently relieves the pressure ok.

But seriously, DO NOT just drive into your garage and go unplugging your lines, unless of course you don't mind gas EVERYWHERE!!! That could end up with some injury for sure.

 

The newer trucks don't even have the valve. I have never done anything to relieve any pressure and there was none there. I get the slow run out of the gas in the filter and the line, just catch it with a rag.

 

well there are normally two places you can bleed the pressure one is the valve on the fuel rail and the other is unplugging your inertia switch and running your engine till empty (or atleast on my 02). But i just finished and i did not need to bleed pressure but i did get soaked in gas i was not expecting all that haha!

 

No need to relieve pressure. The most that has ever came out of mine during a filter change was about 1/4 cup.

On the matter of getting gas everywhere, do you change the oil without a catch pan? NOOO

OP, if you change shocks I will recommend BILSTEN. It is a good precaution for tire longevity.

 

That's why in my opinion is it's a "good idea" to bleed pressure if you can do so easily.

 

bleeding is for *****s. Just sayin. Yeah its under pressure, but not enough to worry about

 

Yup, just dont have yer face (or ear, that hurts...) right by the filter when unclipping and yer good to go.

Nope, I don't. But once the engine is shut off, there is no oil pressure. But there is still fuel pressure once you shut the engine off, no.

Obviously by other answers here some folks have done it without relieving the pressure and gotten away with it. Clearly some have not as well. Considering it is a 30 second procedure (at least on my 97 it is), seems kind of foolish not to take all that time to do it.
