Fuel line chage

So I didn't think there was any need to post about fuel lines being changed. Felt I've had a air leak in the pickup since we got the coach. Yesterday I got the tank out and one of the  -6 lines showed evidence of seepage but no smoking gun causing the air leak. Was looking over the unremoved lines cleaning and preparing to pull tomorrow. So lines at tank show signs of cracking but no leaks. Went back to the filter- pump assembly at the back of the coach. I had replaced the filter and bleed before driving home after purchase. Well I pulled the covering back on the #10 pickup line and it too also looked okay, cracked but not leaking. I grabbed hold of it and gave it a twist. It was loose, well actually the fitting B nut was loose. Some one prior had never retorqued. I had never removed and it showed no signs of leakage. I'm actually glad I went down the path of changing the lines to biodiesel rated lines, but dislike not finding prior.

Three years ago I replaced my lines, my self,  because engine refused to start, after parked a couple days.  There were no signs of leakage, just small cracks in lines going over barbed fittings or at sharp bends.  After replacement, problem solved.

Scott,  Congrats on your solution.
Did it myself, in front of my home, approx 15 hours spread over 4 days,  working at my own pace.  Had a neighbor help lift fuel tank to re-install, which took 10 minutes. This was after trying to get a shop to bid the work and start the repair within a week.  Lowest estimate locally was $2500 plus parts, and all were booked up for 6 weeks out. 

No regrets in doing it myself.  I had not tackled a project of this magnitude since high school, 60 years ago.  At that time I thought nothing of pulling differentials, transmission, engines, etc. to rebuild or replace. The past 60 years. I found it more prudent to pay an expert.  Now recently retired, I had the time, the skill, and it gave me a better understanding of the Foretravel underneath. I knew also, giving the rv to a shop, could take up to 2 months for me to get it back.

Still need to finish aqua hot and generator. They look harder than the rear. 107 degrees today. Lost the will to continue at about 3. Too hot. Yes my hats off to anyone who changed these by themselves. Front lines look worse than the rear.

Jack I have read your post on this and other things many times. It's real easy to sell owners on simple things like being able to start your coach. Glad you didn't follow them down the rabbit hole too more repairs.
Although I found my loose line, I'm really glad today that I'm changing the lines. The return 1/2 line could of very well caused a major incident. It wasn't failed but was hard as a corn chip.

 I helped two owners each change their own sets of fuel lines, engine, generator, and Aqua Hots.  It's not for the faint of heart, it's a pain to pump the fuel, then remove the tank, then pull all the lines thru the bulkheads.  It took all 3 of us, 6 hands, lots of towels and drip pans, and lots of feet of hoses.  Both of the owners are "gear heads" and mechanics with lots of tools and skills.  I'm happy the PO had mine changed just before I purchased the coach.

Jack, $2500. I'm not paying myself enough. Also quote"  I knew also, giving the rv to a shop, could take up to 2 months for me to get it back. " and never really know if they gaffed off anything. I actually found many other items needing attention, cleaning and painting. Just would prefer to extend some of this out for a different time, too much fun all at once.

My issue is that tearing apart my coach to that extent is a no go on a city street. And I lost my free under cover storage when the owner (my friend) died in March. No major maint at the storage facility either.

Jerry I must agree with you. Too big a job to do on a active street. I spent weeks just getting fuel tank empty. Been busy nonstop since we purchased on many items. Used my dodge to transfer fuel too. I would not be surprised if you put out a help request someone would let you use their place and possibly even help. Lots of good people on the forum. If your lines are 20 years old they are at the end of there usefull life. Luckily it's diesel not gasoline. IMO

The only issue I had, doing it on the street was, interruptions by people driving by, stopping to ask what mfg made the rv, and what year is it.  Averaged a little over 3 hrs actual work each day starting Monday morning, finished Thurs afternoon.  It took 4 days as I had to get fittings made, measure and pickup neccessary fuel lines, and tools.  Pumping the fuel out with a 10 gal min 12 v pump took less than 45 minutes. Pumping from one vehicle to another risks contamination, just be aware of neccessary protection.  I filtered the best I could, and left probably 5 gallons of fuel in the bottom of each drum as I felt that contained any likely contamination.  The following is the 12v pump I used, bought new with 20% off coupon, and sold on craigs list for $15 less than I paid.

Jack, My issue is that even though I don't live in a community that tells me what color to paint the house. There is one retired teacher that lives four doors down. she will complain to neighbors (not to me) about the coach being parked on a dead end future street that was permanently canceled. So no traffic, no driveways, No sidewalk, no front doors to the two homes there. She just doesn't like to even see it on that unused blacktop at the side of her home. She has one small over sink window on that side.  Unfortunately, City ordinance backs her up. Technically I'm supposed to only park for 24 hours for the task of loading/unloading. When the coach is parked in front of our house. She is fine. But if I started to tear into the coach in a major way. I'm toast.

The Saga continues. I had to go back and order a additional 50 foot roll of 3/8 hose. I ran out of hose before I ran the aqua hot filter to aqua hot line. Also need line for the generator filter to box and all lines inside of the box. I can put the tank back in and snake the aqua hot line Over the tank to the front of the coach when in comes in. SJK marine sold me the second box of 3/8 at near their cost and included shipping although it was below there minimum for free shipping if I keep/not return the 1/4 hose that I didn't need. Very nice of them. I'll always have a use for fuel line. Also because I was unaware of the Aquahot filter location I needed to move the coach over to open the generator side door. Used a five gallon can and put both the feed and return line in it and fired it right up to move.
