Took my truck in for oil change, transmission service, etc, told them about my fuel leak where the lines go into the top of the tank. They called back and said that the pump was bad. I asked which pump, she said the fuel pump. Couldn't give me much of an answer, had to keep putting me on hold and talking to the mechanic. Anyway, says they are going to replace "the fuel pump" and repair the fuel lines. That alone is 685 parts & labor. Then with the other routine maintenance stuff, brings total to $1285. Sounds like I'm getting burned, what do you all think?

I think I should call back and talk to the mechanic himself. I had an appointment for 9AM saturday, and truck will still be there until tomorrow. I don't really know what to ask, but I never had any problems with the stupid fuel pump, just a leak in the rusted fuel lines directly over the tank. Dammit! I'm no mechanic, I just need a truck that runs! Something doesn't seem quite right here.

 

Well that sucks. I guess those pumps made from unobtainium are quite expensive (seeing as there is no "stock" pump in that location on a 99). Either that or they found the stock lift pump is bad and they are replacing it with the new in-tank version. If that's the case, the fuel leak might be a different and separate issue. Considering that a lift pump from NAPA is $200 and about a half hour to install and you'd still have to fix the leak on top of the fuel tank...I guess its a toss up. $685 is a lot of money any way you look at it but that tank may have to come down to fix the leak anyway. Maybe you can negotiate on the pump replacement a little. Then you don't even get dirty.

 

No, No, No.

My god buddy, you can order a Vulcan or Scotty kit and replace the lines from right next tot he tank, all the way up to the injection pump for between $110-$165 (Vulcan being the cheaper)

The lift pump is about $150.00 at Napa or about $230 at a Cummins dealer for the same pump.
I'm comming up with about $260-$375, and you'll know the job is done right.

They're going to replace your stock lines with more stock lines that are undersized and have quick connects and other restrictive fittings.

If sounds as if they are trying to sell you the "in-tank" lift pump, which if it were me I would NOT want.
If you order one of the kits mentioned above, you will get the right fittings for that F/P gauge you've been talking about too. (Scotty being the more expensive, but more complete of a set up).

 

Walbro, or equivalent, not NAPA ! You don't need a big line kit.

That's exactly right, P.J., and armed with that knowledge you need to go in there, eye-ball it yourself, and talk to the mechanic yourself. Won't let you do that? Then pull the truck outathere!

 

Oh, I got all exited and just realized you said OVER the tank.
Now I'm not sure, but I stand by the price qoute being HIGH anyway.
They many be into a lot of labor with dropping the tank, or removing the bed.
Dunno.

 

You never quit do you?
I didn't say he Needed a big line kit, I just though I was giving him a cheaper alternative to the dealer putting an in tank retro in that he will NEVER be able to service himself in the future.
You've linked that thread in 5 other threads and it is getting confusing.

 

I think I'll call em and say NO to the pump deal, look into scotty's kit. Thanks PJ! They weren't going to work on it til tomorrow anyway. Hope their shop bay exhaust fans are working good, they're gonna know what that cummins sounds & smells like in there. I just have to find a shop that can work on this truck, everywhere I've been is scared to work on diesels, no more dealerships.

Whoa, I just posted and there were like 4 more resposes. Maybe I'll get the truck back with the leak, which has been spotting my driveway since June, and look into bigger aftermarket lines and a different lift pump setup. I hate being ignorant about this stuff, and having to rely on what the dealer is saying. Glad you all are around, I'd be spending some big bucks and borrowing some more problems.

 

How bad is it leaking? Something like that I would just dry up and glob some JB or equivalent on there. Now, if you drop the tank and it appears that the rest of the line or other lines are as crappy, you may want to get some lines and replace them.

If it is just one spot, I have repaired tanks with the fixxer upper stuff they sell and had great success. Don't see why it wouln't work for a line.

 

I climbed under there with a flashlight, and the where the lines turn down and enter the big cap thing on the top of the tank, there is a bunch of rust, and some leaking. It leaves a beer can sized spot every time I park it. I need to get it fixed sometime, DOT won't like it if they check me, but I don't want to pay a bunch for crappy parts if I can upgrade it for similar $. I think all the lines should be replaced probably, she's mighty rusty under there.

 

Answered that question.

Either way, the dealer is going to rape you on ANY part they sell you and they don't have to be competitive on labor much either.

 

That's what this site is all about...learning how to do it, where to get the parts, and doing it yourself!

 

Is there a fuel pump in the tank? I called NAPA, and they said they thought there was one pump on the block and the other was in the tank. High pressure pump and low pressure. Somehow I thought the lift pump, which I guess is the low pressure pump, was on the block, or close to it. I need to figure out which daggone pump they're talking about and order an aftermarket replacement. I spent 45 mins or so going all through the phone book, finally found one tractor trailer dealer nearby who services cummins and said they could do the work. No one else could work on it, or even knew who to call.

 

Where again are you?

It's the "lift" pump. Just behind and below your Fuel Filter housing.

 

That's where I thought the lift pump was. Napa didn't know, I guess. This is one confusing issue!

I'm in Salisbury, home of...NO diesel mechanics!
