We bought a used cat paver a few months back and there is a bunch of rust in the fuel tank. Our paver operator keeps the tank full as much as possible to try to prevent a bigger issue. Hasn't caused a problem with the machine or fuel filters yet, but want to address it before that happens. Anyone every had to deal with this much? I'm trying to get some kind of plan together before we get into all the winter maint. In the shop. You guys are the first I'm turning to, haven't done any research yet.

Most fuel systems draw an inch or two off the bottom so more than likely it'll be fine. On the other hand, being a paving machine, should it go down in the middle of a job would be a real problem. If it were me, and the tank isn't that big of a job to remove, I'd either have it cleaned/checked out, or replace it.

I've taken tanks off and power washed them out, old farts said to put gravel in them and shake around. both of these require removing tank and cleaning/drying very well.

I currently have a loader with visible rust in the tank, I just change the fuel filter every 30 - 40 hours (It sits at a stock pile most of the time).

How much will it cost you if your paver goes down in the middle of a paving job? Probably less to take the tank off and have it cleaned and lined. Plus the peace of mind would be nice, I'm sure you have enough other things to worry about.

We'll def do something with it in the next few months. It's a high hour machine and we took delivery and put it straight to work. We'll get it in the shop and go over it good when we can't pave anymore this winter, just didn't know if anyone has a good solution, coating or something that worked well for them. At the least we'll take them off and try to clean them up good.

This is a big concern and the main reason I want to start to get a plan together early! Been there and done that, paver quits with half the hopper full sucks. We do have a second paver though, wouldn't totally screw us. Not that it would make a difference at the time though as it would be unlikely to be at that specific job, would just turn into a emergency for our lowboy driver.

I bought a used excavator with 8,000 hr and I took the tank off and cleaned it out the best I could in the shop than put it back on. Depending on the way the filters are set up a good cleaning there can make a big difference too.
I did the same with the hydraulic tank except I also changed the in tank screen. I could not believe it. The screen had never been changed and it was ready to disintegrate and spread through the system. :eek: FYI the fuel hose was so brittle that I grabbed it and it broke in half. All that stuff wasn't that expensive but It sure made me feel better about the reliability of my machine.

I know what you are saying. We've done the same thing multiple times. Bought a Jd dozers last winter with a good bit of hours and it took 2-3 trips in and out of the shop before we found all the weak spots. The cold weather seems to help you find the weak spots pretty quick. We do send a bunch of time and $ in the shop each winter going through everything, but it seems to work well for us because we don't seem to have any major issues when we get straight out in prime time.

We've gotten a lot of older equipment from auctions and had pretty good luck, but I think we're going to have to start to upgrade slowly and replace some stuff with newer used pieces. I still don't think we'll start buying new though, just seems like they are way overpriced and easier to get a late model used machine for far better deals with a good bit of research.

Find you an old school radiator repair shop (you know the one with the older guy that looks like he lives there). They should be able to clean and coat the inside correctly. Solve the problem for good. Getting a new tank would work but it will eventually rust too.

I was just going to say the same thing regarding a radiator shop. As a side note, I just had a truck go down last week because of this very issue. Sucks.

Thanks guys. Just got the machine in the shop the other day, but haven't gotten to the tanks yet. Screed is off and getting cleaned up and trying to figure out what wear items we'll need to replace.

We were very lucky not to have it go down, so guess that's a win. Just hope it doesn't cost a bunch of cash to get them back in shape.

How do you know there is loose rust in the tank?

Again, a radiator shop can flush and clean the tank, otherwise your fuel filters show catch any debris coming throough the fuel supply lines. On our truck, it was getting a limited amount of fuel through the clogged filter. The injection pump/lift pump would try to pull more fuel than could flow through the filter that it would starve itself and shut down. I didn't flush the tank, but changed the fuel filter and water separator filter and cleaned the screen at the lift pump. She's running like a raped ape again.

Not sure yet if there is loose debris, but a good bit of rust around the filler neck. We're going to drain and stick a camera in them to see what we can find. Just trying to prevent what you just went through.
