Noticed I've been spotting up my driveway with diesel, and found its leaking right where the fuel lines run into the top of the fuel tank. There is some kind of a big cap on the tank that the lines connect to, and I think the fittings or the line itself has rusted through. It drips a little while idling, and will leave a spot about 4" every time I park it. I've had a hell of a time with rust under the truck, whoever owned the truck before must have done some serious winter driving. My brake lines also rusted through, above the fuel tank, and I went blasting through a stop sign. How bad would it be to fix the fuel lines, or replace the fittings on top of the tank? It seems simple enough, but getting to it is the hard part. Anyone else had a similar problem?

 

i had the same problem this summer,i dropped the tank by removing staps and replaced the sending unit with a reman from dealer,and yes the big cap holds it in,then i ran rubber fuel linse all the way upto the motor.

 

There are two ways to get to the tank and lines, do a search on fuel tank repair and or tilting the bed. Some like to do the tilt the bed and if you have hitches or tanks and stuff in the bed do the drop the tank, I have found using a motorcycle lift or using a transmission lift with some tie down straps to be very helpfull in the drop method. On the rust there are products out there that chemicaly change rust that you could use and then seal over or undercoat. Goodluck,,Rick

 

I would imagine you have a hard start problem as well??

 

That's a good idea, running new lines and all. I will have to do that soon, my driveway is dissolving. I'll see if I can find a new sending unit locally, and give it a try. I guess I'd have to bleed the lines after I replace them, is that hard to do? I've had to bleed the tractor a couple times, and that sucks.

No, it hasn't had any trouble starting yet, she fires up almost immediately after the light goes out. Thanks for the info!

 

A link to Thread a few months back...

 

When you replace the sending unit/pick up get the newer models that are plastic, they NEVER rust. I have done a few of these for people.

Thanks for the link Nomad. I will look for the plastic unit. This truck likes to nickle and dime me to death. Or $50 and $100 me to death anyway. Dammit. Lift pump, fuel lines, fuel sender, brake lines, the $1210 , 8 day brake job from hell, oil sending unit... I better quit thinking about it, the transmission might just fall apart in the driveway out of spite. At least she sounds good though!

 

Add another 400 bucks to your list. Just did mine about two months ago. It's called the tank modual and it aint cheap! I think all the new ones they are producing have the plastic elbows on them now. About time!

 

Look for them on ebay. They usually can be had for around $75 to $100 bucks

 

NO, DON"T buy new, go to the junkyards or as mentioned look on E-bay, just get the plastic one. I paid 125 for the first one I did, that included the tank, the next few were 50 buck with no tank. Anyone need a 35 gallon tank??

 

This resorce is a great help with our trucks. Wish i had found it a few months ago. Thanks folks.

 

Couldn't you just put a bottom feed on the tank and the same set up on top of the tank for the return line? The 2 lines on top the tank leaking could be closed off some way to keep them from leaking. Would this solve the problem with out having to replace the unit?

Just a idea

Thats what I'm doing. I machined a fitting for the bottom feed and I need to get a filter screen and make and aluminum housing for it to pre filter the fuel before the pusher pump, that along with a shut off valve I think will be cool.
