Hello all! I'm back in the powerstroke club again, finally ditched my money pit cummins. I scored a 97 7.3 single cab 2 wheel drive with a service bed for 1,000 with 201,000 on it. I've been drivin the truck for about 2 weeks now and am having some issues.

1- fuel leak on top of motor
I smelt it and can see a puddle under the fuel bowl. I took the cover off and looks like the water in fuel sensor is leaking. Is this common?? Where and what else to check?

2- rough idle
Truck has a rough idle to it. I ran my genesys system on it last night, and it had a cps code in it. Cleared it, still rough. No new code yet though. Any thoughts??

3- intermittent brake light on dash, kills cruise.

The dummie light on dash comes and goes as it pleases, usually when sitting still. It'll kill the cruise going down the highway. Sometimes with the blinker it'll kill it too, and also seems to me like it makes the torque converter dissengauge too.

Other than those their, that's about all I can find wrong with this steal. We put a 6637 mod on it last night, along with 3-1/2 straight pipe too. Plan on ordering gauges for her, and getting either a PHP or Tony wild man for it, and callin her good. Any help would be much appreciated. Thanks in advance!!

Running rough can be caused by low fuel pressure.

Low fuel pressure can also damage the injector nozzles.

Fix the leak first.

Check the third break light ( the one at the top of the cab) I understand they have been know to cause some weird electrical faults when they are blown or shorting out.

1 fuel leak. if its at the back of the fuel bowl it could be the sensor or the rubber fuel line that go into the back of the bowl. i would get a fuel bowl o-ring kit and replace the line also clean the fpr screen

2 i would get a new cps as they are known to fail and check the pigtails for the uvch and see if there are any burn pins

3 check the third brake light and also check the e-brake pedal for worn spring and dirty sensor for it.
