Group buy Parker HTFL fuel line?

I'm wanting to replace the fuel lines in my coach and would prefer to use the rigid plastic line by Parker. This is the semi rigid thermoplastic made specifically for diesel/biodiesel, not air line tubing.  In order to obtain it, though, will need to buy full rolls.  The sizes will be the HTFL-10B and the HTFL-8B.  Cost for the 10-B will be 3.50/ft, the 8-B 2.50/ft.  I'll ship it at your cost or you can pick up in Port Aransas Tx.  If several folks are interested I'll put the order in, ship it, you pay when you receive.

The roll lengths are 250' and 500'.  If, perchance, you have found somewhere to purchase it in cut length quantities I'd sure appreciate contact info.

I may be interested as I am planning to replace or have the fuel lines replaced. I have a 99 u320 with an Aqua hot. Can you or someone tell me the quantity that I may need of each size?

Called Wilco-no dice, referred to Hufco, a full line Parker distributor.  Full reels only, non stock.  This stuff is like unobtanium and typically the distributors are unfamiliar with it.  Somebody should open an ebay store for cut lengths.

Philtravel, I know for a 36' coach typically supply and return lines are 40', each, supply and return.  Genset is 40' total.  No idea on aquahot.  If I use it I will make these diameters work for everything though I expect you have four different size lines on your coach.

As discussed in the earlier posting, the original fuel lines were a 5/8" ID for the supply line and a 3/8" for the return. 

However, the 3/8" return fits pretty loosely on the nipple at the engine and requires a very tight clamp to keep it from leaking.  My opinion is that the nipple is probably designed for  a 5/16" ID hose rather than 3/8".  Have you figured out how you are going to clamp/seal the HTFL to that non threaded return clamp?

The generator lines for my 8KW Isuzu were 3/8" ID supply and return but there is no reason for them to be this large from what I can tell.  I did leave the supply at 3/8" up to the lift pump but 5/16" ID hose was the correct size for a snug fit at the push on nipple for the engine mounted fuel filter.  I really couldn't see any reason for a 3/8" return line from the generator, seeing how small the hose from engine to the 1/4" NPT connection is.  I changed my generator return tubing to 1/4" all the way back to the fuel tank and haven't had any issues with it.

No, I was unaware of this...the coach is in remote storage and I was assuming (I know, I know) the lines were reduced one size from supply to return.  Having a hard time seeing why the return line should be that small especially considering the return length.  My intent is to transition from the semi rigid plastic to a Gates barricade line from filters to engine and back from pump until out of the engine compartment proper.  Heat and vibration isolation. 

Your Trident hose solution is looking better and better.

I'm sure you could have a short piece of hose (6" or so) from the engine return nipple that connects to the HTFL with a coupling or something.  Wasn't trying to dissuade you from doing anything but I haven't seen any pictures or discussion about what FT was doing when they upgraded the fuel lines to plastic regarding this?  Clearly they found a solution that works and I would doubt that they were able to clamp the HTFL tightly to the engine fuel return. Maybe someone who has had it done can comment on how FT handled that connection.

When going to the trouble to replace the fuel lines, be sure to add a fuel cooler (transmission coolers work very well) in the return line.

With the lack of air circulation around the fuel tank (in the basement) fuel temperatures can rise, particularly on hot days with less than 1/2 tank of fuel.

I think I should get in on this.  I know I have at least one cracked line.  We are talking about the main engine fuel lines right which should be a larger diameter?  My aqua hot and generator fuel lines have already been replaced by a prior owner.

FOT replaced our fuel lines with the Parker material. FOT replaced all the fittings on the fuel tank. I don't know what other fittings they replaced or modified. They used some short sections of soft hose on some of the connections. They replaced the lines to the main engine and the generator. All worked well for a year except for a fuel leak somewhere near the top of the engine.

Bernd Ramspeck in NAC replaced the short rubber sections with high quality hose and good fittings. He also identified the leak near the top of the engine. He was able to machine the end of the injector line and fix the leak by reinstalling it and properly torquing the connection. Coincidentally, that leak started after the FOT mechanic was loosening/tightening the connection on the #1 injector line to bleed air from the system after they replaced the fuel lines. Don't mess with the injector lines!

Please pardon my tardy reply.

Not sure whom you visited with at WILCO but I'm surprised with your post.
After seeing the pile of boxes headed out the door (I'd guess) you may have not been visiting with the right party. 
News to me, when I was off-shore we used to get their supplies flying in all the time. 
I'd give their "will call" desk another call (I will.) pc.

Hello Chuck,  I've just called and visited with DAVE PRADO and it was news to him ((also)) that WILCO does not ship (it's his duty with WILCO.)
PLEASE let me know if you have another issue getting something shipped.

Hey PC,

Problem was not with shipping, they did not have this line available and referred me to another supplier who also didn't have it.  I have pretty much abandoned the idea of using the HTFL line, looks like Parker Wavemaster is readily available for around 3.00 a foot from numerous suppliers.  It's rated for 100% bio-d.  It's bulkier and not as slick an installation but available unlike the HTFL.

Not enough interest from others to justify buying full reels.

I've got a 50' unopened box of the Trident 365 1/2" ID that resulted from me not planning out everything very well and waiting far too long to try to send it back.  It is yours if you want it, PM me.
