Need some 1/2" id submersible fuel line

I dont' see where any is rated for submersion?
 
ohh I'm right there with you Zim
haven't had a chance to check my PSI problems but wouldn't mind some extra tubing like this, even if it's not the problem

seems like unobtainium
 
Is 1/2" needed for a factory TBI sending unit? Nah, more like 3/8" or 5/16" right? This is what I'm looking for I think, the hose coming off the pump itself.
 
Ill be at work at 3 and see if gates has a number for it. Were your parts stores unable to order some in?
 
I know i replaced mine like 6 years ago. I don't remember buying anything special and I haven't had any problems, either. I was thinking I just bought a chunk of fuel line? The one that came in my (used) TBI tank was very thick walled, but later split down one side - hence the replacement. If that's the factory solution, maybe there is something better?

It seems like I've seen it supplied with a new fuel pump, but I can't remember what vehicle that was for. Some newer cars have this clear plastic corrugated line that seems to be everlasting. Something like that could be scored at a pick-n-pull unless you are determined to go new.

I didn't either but may be worth a call. I found some 5/16" online but nothing for 1/2".

Was reading a vendor for Pushlite hose (Parker) that it was submersible.

No one had anything in stock, which at the time I was ready to ship some stuff to Kert and was wanting to include that for the fuel tank build. If you come up with something post it up for future reference..:bow:

I've read the fluoroelestomer tubing is fuel rated, and its the same type construction throughout, wonder about colapsing under vaccum though?
 
Mine is after the pump, so it's under pressure.
 
Gates Submersible Fuel Line Hose (4219 Series)
Gates-Submersible-Fuel-Line-Hose-(4219-Series).jpg
This fuel hose is recommended as the premium choice for clamped hose applications on all fuel systems, including fuel injection systems. Not designed to replace coupled hose assemblies on fuel injected engines. Approved for use with leaded and unleaded gasoline, diesel fuel and gasoline blends of ethanol, methanol and ethers (up to maximum concentrations allowed by the EPA) 100% methanol or ethanol and B100 biodiesel, up to 135OC.

Key Features and Benefits:

• Outstanding fluoroelastomer liner resists permeation and alcohol
• Outstanding oil resistant tube combats heat.
• Polyester braid reinforcement increases strength
• Oil, heat, ozone and abrasion resistant cover
• Meets requirements of SAE 30R9
• Superior for service life over standard fuel hose

Warning: Do not submerse in gasoline.

Maximum temperature to +150OC.

Intended for use with fuels where MTBE concentrations are no greater than 15% by volume.





Then whats the point of rating it as submersible line?
 
more info:

SAE J30R10 Fuel Hose
This submersible hose is generally constructed from reinforced rubber core with a flourocarbon inner and outer shield. The flourocarbon shields are supposed to "protect" the core from gasoline. Otherwise, the fuel will permeate (or soak in) the rubber core, causing it to expand and weaken the bond with the reinforcing fabric. Safe? Read on:

First of all, the SAE J30R10 hose specification does not include E85. Let me repeat that: SAE J30R10 is not for E85. The ethanol molecule is MUCH smaller than "gasoline" molecules, which allow E85 to permeate easier than gasoline.

Let's assume the flourocarbon shields could prevent the permeation of E85. Even so, there is no flourocarbon "shield" on the ends of the hose, because the hose has been cut. If the hose end(s) are submerged, the fuel will permeate through the end of the hose, past the hose clamp, into the pressurized region, causing the rubber to expand, separate from the reinforcement, and eventually lead to failure.

forget about anything rated less than r10, although better than the old 80's f.i. hose (rated r6) the permeation rate is still unacceptable for long term use.

wow, that's a lot of info. I'm watching intently cause I haven't a clue what I'd be looking for otherwise :(

Thanks Zim
 
My sons jeep has a short piece of hose in the fuel pump housing, submerged if there for than 1/2 a tank.. Is there a way to find out what it is?
 
Hey it could happen!!!


hahaha, I know its overkill Scott, just don't want to have a restriction on the inlet side of the pump...4 5/16" lines running to a central pickup puck and 1/2" line from the puck to the outlet of the tank....I'm running an external pump so everything on the inside of the tank will be under suction, and I know pumps don't like to suck as well as blow so the less restriction the better, and I already bought the fittings for like $30.

Here is what Jim @ Harmon racing cells:

Subject: Re: 1/2" submersible fuel hose


Dave,

For hose, we do have a style we use in all of our fuel cells, though I'm not particularly sure of the SAE rating. It's Parker Push-Lok 801 series and we've been using it in fuel for well over a decade, in fact we still see fuel cells from the early 90's that have Parker 801 that's still flexible and leak free. The only thing with this is it's not specifically rated for E85; if that's what your running I'd suggest something with a PTFE (Teflon) base as it's pretty resistant to all fuels, including alcohol.

You can probably find something close by at your local autoparts or performance store that would fit the bill. With hoses, it's not specifically about the SAE rating as it is the material that it's made of. Most manufacturers use similar styles and there's a few I would stay away from as they tend to get hard and leak over time when submerged in fuel. Jiffy, Aeroquip, and Russel/Edelbrock are ones we replace more often than others; Parker and Goodridge are probably some of the better ones as we don't replace them very often. What you want is something made of a nitrile-based (or synthetic base) rubber. Just try and avoid things with a neoprene outer coating (or inner) as they tend to dry out and crack. Hydraulic hose will work in many cases as it's designed for pertolium oils (like gasoline) along with marine hose. If it's rated for deisel or hydraulic fluid it will likely hold up when submerged in fuel.

If you want to try searching locally you shouldn't have a hard time locating some; otherwise let us know and we can ship some out to you.

With 4 pickup lines, do they each have a float or something that closes them when they are in air?
