FUEL LEAK?????
I have fuel dripping under my truck. I noticed what looked like an oil leak in my driveway. When I crawled under the truck there is fuek dripping down off of the Tranny. Looked under the hood and behind the filter is what looks like a fuel pump with 3 rubber hoses coming off of it. Behind that there is a large brass nut with brass tubes going into the "valve covers". Under the large brass nut there is a "puddle" of fuel. I had my wife bring the truck up to 2000 RPM's and there is a small drip about every 20-30sec coming from what looks like under the brass nut. I had this same problem about 15 months ago. Took it to the shop and they "supposedly"replaced everything n there to fix the problem. My question is, is a common occurrance and is this something I can tighten myself? Sorry for the long thread just wanted to give yall the complete story.

From what Ive learned on the site here is that it is a semi common occurrance, you may be able to tighten the banjo bolt a little, but I would be carefull. You can get at it with a 1 1\8" end wrench. Good luck.

What is the "weep hole"? I had all this replaced a little more than a year ago at over $1,000.00 dollars and dont want to do it again. Of corse the shop has a 12 month 12,000 mile warranty, and they want $100.00 to diagnose. Will not be going back!!!

The "weep hole" is where the fuel pump leaks out when it goes bad. It's on the bottom of the pump so you need a mirror and probably flashlight to see if its leaking. Do all the hoses off the pump look new or old rotted blue hoses?
You're right for sure by staying away from that shop at that cost.

The hoses are new blue hoses and the clamps are tight. Do the fuel pumps go out in just over a year or do you thank the shop worked me over??

I didnt want to start a new thread but here is my issue.
I was driving today and Suddenly I started smelling Fuel... Well when I came to a stop I got out and Check under the truck.. It was Pouring out Bad... My Back Bumper and Tailgate were covered in Fuel...I have a nice undercoating of Fuel now... Even my Hubs were covered in Fuel...Anyways After Checking it out it is Coming From the rear of the engine. It Cost be $40 bucks in Fuel to make it Home... only had to go 40 miles.. But Cheaper then a tow truck. Anyways My question is where do I start looking? Fuel Pump, Injector Pump, Hoses? Whats the Most Common problem?? I have worked on my IDI a good Bit but havent worked on the PSD that much. Thanks.

The common places to leak are: fuel pump, fuel restriction sensor, hoses, banjo bolt, o-ring of the fuel canister and corrosion in the bottom of it. Other less common, the fittings at the rear of the galleries and the hoses in front of the FPR to the galleries.
Good luck.

Well that seems to be a HUGE leak, the first thing you have to do is to clean everything well in the valley of the motor and then carefuly, with a flash light and little mirror, to try to find where the leak is coming from.

Yeah That Fuel Guage Drops Pretty quick when it starts Pouring outta there. My Valley is also full.. looks like about an inch deep... Just gotta find the time to tackle it!
