When should you replace your fuel filter? I have 18K on my truck. Would it be too soon. And also, does it make much difference on what type of driving you do?

 

Well I did mine at around 28K. The mantainence manual calls for it at 15K. I didn't really feel any difference (I didn't really expect any) but it made me a little happier knowing that the filter was fresh.

Takes about 15 minutes to do, real easy as long as you have the disconnect tool for the lines.

 

How do you relieve the system pressure?

if it makes any difference - I am doing this on a 92 with a 4.9

thanks

 

Hi 92

2 ways that i know of..

1..disconnect elect. to fuel pump shut-off or pop (red) valve to up position..start engine, run till it dies. Reset pop-valve or reconnect elect..either way should work. Not sure but that shut off maybe on the pass. side under dash at or near firewall/side wall.

2..if fuel rail has pressure valve (schrade?-sort of like a tire air valve with cap on it) can relieve pressure there...is easy..but really should have the tool with relief valve to bleed air/gas, screws onto that fitting.

Good luck...OT

 

Recommendations on which brand filter to buy? i just turned 20,000, i guess i'll have to change this weekend..

 

the fuel filter is supposed to be replaced at 30k. i personally would get a motorcraft they have never done me wrong.

 

On my 4.9 1990, I change mine every 30,000 miles.
