changing fuel filter

[fordF250]

im going to be changing my fuel filter this weekend. where is the valve at to drain the housing. and also im going to do the fpr mod and clean the fpr screen. and will draining the housing relieve the pressure so i can pull the screen out and change the spring?

The lever should be a yellow or black lever on the front left side (if youre standing on the bumper)...could be on the front right side in a 97 (mines a 95). Just flip it and fuel should drain to the ground. Put a bucket under to catch it so as not to make a mess. The filter may be holding enough vacuum so no fuel will drip but as soon as you loosen the filter, itll drain. You can clean the screen and change the spring at this point.

what is the FPR mod?

[fordF250]

just a mod to the fuel pressure regulator spring to boost fuel pressure, improve idle and throttle response

I like to take a piece of fuel hose (3/8" I think) and slide it over the the drain pipe that comes down the front of the block. That way you can direct it into a pan or something instead of letting splash all over the place.
FPR mod: OBS FPR Shim and Gauge Install

what does the drain pipe look like? i looked today and couldnt find nothing, i did find something off the right side of the fuel bowl below the ipr that looked like it could drain but not sure.

Find your EBP sensor, then find the tube that runs from the bottom of it, in front of the block, then into the passenger side exhaust manifold. If you're laying under the front passenger side of the truck, you will see where this tube enters the manifold. There is another tube that tuns parallel with it along the block, and then abruptly ends. That is the fuel bowl drain tube. IIRC, just a bit above the cam sensor. Might be a good time to clean all of the crud out of that EBP tube http://www.guzzle7pt3.com/ebps.php while you're in there.

i have the ebpv unplugged so do i still need to clean the tube?

The EBP sensor is completely seperate from the EBP valve at the turbo. From what I understand, the sensor is vital for supplying accurate information to the PCM, and effects various things such as fuel economy. I know some of the guys have deleted the tube and sensor completely, and I'm not sure what their results have been. I would clean the tube, replace sensor if need be, and leave it intact. That's just me though, I've heard different opinions on the matter.

well i got everything done. the ebp tube was clogged solid and the screen and white plastic thing for the fpr wasnt there. just an oring. so im not sure what to do. cant really tell to much noise difference on the hpx line but it smoothed out the idle too. thanks for the help
