Wanting to replace all fuel lines
 

I am going to upgrade all my fuel lines this spring and would like to use that blue fuel hose that I see in the cummins but I can't seem to find where I can purchase it. I thought trident made them but I can't seem to find a place I can purchase it. Have you seen it?

price per foot?
 

what's a fair price

junior's has it @ 70 cents per foot

.70/foot??? that can't be uscg approved.

I think I found a source...it is not cheap though

Call Rose's marine in Gloucester, they have what you want.

liking that double crimp tho
never seen metal flex fuel line b4

Sandman,

You leave me asking lots of questions.

Seems like your hung up on the blue hose, that is just a color.

First, why? Is not the hose your using now made for fuel and fire retardant uscg app etc. Are you having problems?

What kind of fittings do you have on your hoses now. Are they hydraulic style metal ends of hose barb and clamp?

The kind of hose you posted is way overkill thus 12 bucks a foot. Your looking for hose from you fuel tanks to engine and a return. For the most part your not dealing with and significant pressure. USCG A1 hose for gas and diesel for your application should be three times cheaper than that per foot.

If you have metal crimper type ends or want to convert to that there is a Parker Hose place is Weymouth that can make them for you. You can also make your own with Aeroquip fittings which is a reusable multipiece fitting which makes it field serviceable. I use these quit a bit on hydraulics.

The way your original post is written it just really sounded like you don't know what you need, want or required to have and your going down a $$ road you don't need to go down.

Beamie,

To some degree you are right. Right now my fuel hoses are OK and they are the standard heavy black uscg type one fuel hose. A couple of them are still the original vintage (2003) but a couple have been replaced. This past fall I saw a new boat that with a cummins that had these heavy duty blue hoses with the crimped fittings and it looked really robust. While the standard black ones work OK and meet the uscg requirements I never liked the screw clamps they use on fuel lines, looks cheap to me. I really liked the look of the hydraulic style fittings and the blue silicon(?) coated hose in the engine room esp when attaching hoses to the engine.

I agree that what I am looking at is little overkill for my application but I don't need a lot of it. Honestly 40-50' would probably be enough.

I also like the look and idea of user serviceable Aeroquip fittings but are they rated for marine use? I have usually seen them race equipment with the SS braided hoses.

Aeroquip fittings look all pretty and sexy, but stick to the regs, they're not approved.
Double clamps, they work fine.

So why do you think the pretty Parker hose is better than Trident? Or do you just want something pretty?

Likwid,

Can you show me where an Aeroquip style fitting is against regs. Once together this type of fitting is no different than a permanent crimp type. This would be considered a sleeve and threaded insert.

I am curious, show me where I am wrong for my own benefit.

Sandman,

I hear what your saying. I'd have them made up at a shop if you go that route. You will need adaptors to go from hose to machine and some swivel ends.

I'd keep it simple though.

You can also get a fire retardant jacket (sock) that goes over the hose after the hose is made for a heat shield. You can put this near the engine.

One of the reasons is I like the looks and I like the fact that the fuel hoses stand out from all the other hoses. The other reason is the ruggedness. Combine the two and I don't mind $12/ft. I might buy the crimping tool and see if I can do it myself getting the exact right length may be a trial and error thing with this type of fitting... I may have to cut, dry fit, and cut again, dry fit it to get it just right.
As I said, I know that SS clamps and a black trident hose gets the job done but the parker set up looks much better IMO. Its kinda like... I could fish with a stratic but the stella feels and looks better. Both get the job done. Do I need to do it? No, what is in there now is fine and you can take it apart with a screwdriver but I just want a better fuel delivery set up. This is part of upgrading the entire fuel line/filter/priming pump set up. My racor mount is a basic two unit with switching lever and it uses the spin on cartridges with screw on plastic bowl. It works but they now make much nicer units with vacuum gauges and better filter assemblies and integrated priming pumps. While this unit is out I want to re-do all the fuel lines at the same time. This is what has led me down this path.
I was originally going to do this only if I re-powered but now I am thinking I might do it anyway. It looks like an easy job that will add a professional look to it.

Thank god we're not dating, you sound like you'd be high maintence and always want the lobsta dinner when going out to eat.:rotf2:

You can't crimp those yourself. That is done by a hefty hydraulic machine with different sized dyes. That is why I suggested the Aeroquip that you can do yourself and I am pretty sure is ok with the CG. I would like to hear what Likwid says thou.

Its not a case of them being against regs, its that the USCG has never certified them for marine use.

Blue hose doesn't make it look "professional".

All I can say is there used all over the Marine Industry on the ships I work with never an issue of being "certified".

How many were US flagged? :hihi:

And were they used for fuel delivery or for hydraulic use?

All US flag Likwid. Mostly hydraulic system usage but some fuel. Like I said I have never seen an issue where "the fitting" itself had an approval number. "Hose" yes, most of the manufacturers where it Parker, Trident or Aeroquip all have USCG approved fuel and lube hose but I have Never seen a CG stamp on ANY fittings whether multi piece take aparts or one time crimps. Therefore have never had or heard of any issues. Let me make this analogy. The CG may prefer hose, hose barb and hose clamp. How many hose clamps have you seen an approval number on.....I've never seen one.

Here's the regs on fittings, but not whether they need to be approved or not.

Another one of those wonderfully fuzzy areas.

http://www.uscgboating.org/regulatio...rds_partm.aspx

They're clear on hose clamps and swaged fittings (which as previously mentioned cannot be done by hand) and screw type fittings. (Break out the loctite)

Fittings must meet these standards apparently:

I don't know about that Capt. There not a single CG vessel that doesn't use aeroqip fittings for either oil or fuel.

Well, assuming that's true, it pretty much settles the argument.

And if the USCG has aeroquip...that is what I am going to use. Thanks Machinery Technician First Class Scott Maccaferri for that clarification.

Its true:uhuh:. Chop saw to cut and a couple wrenches to spin on the stainless fittings. CG required us to pressure test them to 100+ % of the rated pressure. Im sure you could plug one end and rig fitting/ pressure pump to do the same if you really wanted to.

i'm bit late to the party...i've been in the hose business for 28 years. I've seen the pics of your boat and it is very clean. You take great pride in it. No doubt, in my mind at least, that it's hard to beat the aesthetics of the Parker 221FR assemblies with brass ends on the motors. A lot of half correct statements here on hose types and acceptances. Aeroquip racing (ss braided with anodized aluminum) is not Aeroquip marine. No racing on the coastie boats. Parker makes trident fuel hose. Trident makes nothing.....I sell both.

When officially testing hose for hydraulic use a reputable shop will PT the hose to twice the working pressure.

I agree. We had a test cabinet at the base in Woodshole. I think it used vegetable oil as the test medium. Can't remember off the top my head what % . Possibly 110-120% of rated pressure. The 47' MLB use the blue hose with stainless fittings (fuel, engine & transmission oil, hydraulic fluid). I can get the specs from the hose shop tomorrow if needed.

If you know of a good shop on the Cape or say Wareham let me know. They guy that runs that particular hose shop is getting canned and either the few Machinery techs at WH will do the work for outlying units or it will be outsourced. Sucks b/c this particular guy has forgot more info than most those kids will ever learn.
