Sputtering/missing - dies and leaks fuel

Truck has been running like a top until recently had to replace fuel heater element and #22 fuse. Truck started and ran for a couple of days and missed a couple of times and died. I was only a couple of blocks from home so restarted it and drove grannied it back home and replaced the CPS. Started but needed a little extra crank to bust off and did the same as before. Started missing progessively worse so I did a uturn and pulled into the drive right as it died. Waited a minute or so and it fired right back up. Got out to pop the hood and noticed a BIG 3' puddle of deisel under the truck. Popped the hood and the valley had a good amount of fuel. Pulled the Y-pipe and checked around. The top drivers side hose to the fuel pump was wet as was the top of the pump. Cleaned the hose and could not find a leak. Couldn't find any leaks around the filter canister. Is my fuel pump taking a dump?

There are 4 wire harnesses going into the valve covers (2 per side/cover). Just for kicks, unplug each one (with truck off) and check to see if any of them are fried / melted.

I recently had similar symptoms, albeit less severe than yours sound and two out of four of mine were totally melted. So I was running on no more than 4 cylinders.

After replacing the valve covers and rewiring new harnesses I was back in business

That was actually the first thing that popped into my mind to check as I pulled into the drive and it died.....until I got out and saw a 3' puddle of fuel under the truck. Checked the filter canister and there was barely any fuel in it at all. That leads me to think it is a fuel delivery problem. I did look at the wire harnesses and they appeared to be in good condition but I did not unplug them. Something to check in the morning. Haven't tried my scanner either because I did not get a CEL and from what I've read on the forum, I prob'ly won't have much success getting codes or accurate data from a regular scanner but I'll try that in the morning just for squirts and giggles.

Ok i had a huge fuel leak not to long ago, my fuel bowl had a pencil sized eraser hole in the bottom of it big big leak. Maybe you should check the bowl itself. As for the missing and dieing dont really know what to tell you besides good luck...

Your fuel pump is shot,I'm installing new pump today on mine.I didn't get the big puddle of fuel but engine would cut off and miss and that ain't fun.All we have are o rings ,hoses and a pump in the valley,the pump leaks from a weep hole.

Guess I should put it back together and start it and try to see where the actual leak is coming from first. Pretty sure I'll be replacing the pump. Where is the weep hole located on the fuel pump? Should I get an OEM or has anybody had better luck/reliability with aftermarket?

The hole as it appears on my Ford replacement is on the right hand side underneath mounting hole.As far as putting it back together I would suggest getting pump and maybe the three small flex hoses, do the install anyway.Pump is around 100 bucks,they say Carter makes most of them,I think you can find a Bosch for another 30 more ,not sure it's worth it.If you have a leak after this,it should be smaller and cheaper .I only suggest replacement because of your chugging symtom

OK. Thanks for all suggestions. I checked NAPA and they have a pump for $109 and a Bosch pump for $149. Waiting on a reply from my buddy at the Ford stealership to gimme a price on a OEM....and waiting for the temps to get above freezing. Sucks when your truck won't fit thru the garage door.

Good to hear,I just back from Ford store with the three hoses I mentioned in earlier post,you need if you choose oem,one package#F4TZ-9324-CA one long hose,one package consist of two hoses,smaller in length#FTZ-9324-DA.The other choices are using bulk hose and you cut to fit.Oh by the way,my "Ford" pump has Carter stamped on it

Good idea. Might as well replace the hoses while everything is apart.....and I can cut 'em if they end up being a b!tch to remove.

I can get an OEM pump from the stealership for $136. Is it worth the extra $30 or should I go to NAPA for $109. From what I just read, most of these fuel pumps are all made by Carter.....don't know if this is true. Guess I should go with the OEM Ford pump just to be safe.
