Hello all,
We have the Gates SAE 30R10 5/16" submersible fuel hose for our in-tank fuel pump system.
Can't find stainless steel ring clamps for the hose and not sure what size clamps to get. If we can find a source, perhaps the supplier can help us determine the correct size. Have searched the Forum and the Internet to no avail.
The free hose measures ~ 0.537" o.d. x ~ 0.290" i.d. for use with 5/16" line.
We would appreciate any suggestions regarding getting proper clamps for this hose.
Thanks,
Don and Susan Jeffers

Do not, repeat, do not use worm hose clamps in the tank with the submersible fuel hose. When I did my tanks I couldn't decide weather to use the spring type or the worm type. So I did one tank with each. The worm type failed to maintain clamp pressure and the piump separated from the tube within the first month. Thank goodness for the tank sender access port I made.
I have not been able to find the hose clamps I'm refering to at McMaster. NAPA, and many hardware stores, have them:

(note - this is just an example of the type, not necessarily the correct size.)
The box they came in called them "corbin clamps).

Well first off I'm not a clamp expert so this is just based on 50+ years of experience. I love worm clamps because I can moose down on them and can give a snug up twist if I want. However if there is any cold flow on the hose the worms can lose their compression. I like the spring clamps as they maintain constant clamping force even if the hose has some compression set or creep. Also the spring clamps seem to have a better uniform compression compared to worms on the smaller sizes of hose, like fuel hose.
Now for some of the specifics of my situation. I did not put a bubble or slight flair on the end of the steel fuel line as I did not want to mess it up if I wanted to undo the installation and reinstall the fuel filter sock on the tube. If I pull the sender assembly in the future I will make it mo better with a slight flare. I will still use spring clamps as the pump does not have any type of flair or bubble. And finally, on the GM OEM instructions they show spring clamps. Most OEM clamps appear to be spring type even in larger sizes.
So the answer to the mo better question is "it depends". For this specific installation, submersible fuel hose, I would say spring clamps based on my experience and the inaccessibility of the clamps.

Steve,
I reckon what you've noted below is spot on and that for in tank installations the flat "wide" stainless steel spring clamps are the
way to go.
I just remembered that Hamilton Standard used flat "wide" stainless steel spring clamps on the short pieces of silicone hose that
joined the ends of bubble "flared" aluminum tubes together. We would put two wraps of special Teflon tape that had glue on one side
around the silicone hose before we installed the SS spring clamps.

Rob M.

Billy,
I am glad that they have worked for you as I have had several problems related to those, Fortunately, they can be tighten a notch if they are accessible.

I posted that clamp because it is the kind that came with my submersible
fuel pumps. Those pumps are installed and working fine for several years
using them. I don't think the manufacturer (Airtex) would supply them with
their pumps if they were known not to work.
Enlarge the photo on this page to see what I mean.

Rob, Billy and Steve,
The nylon toothed clamp and the adjustable crip (Oeteker) clamps will not
hold after the tubing material cold-flows. That is why a spring or constant
tension clamp of some kind is needed. This is particulary true where
maintenance is impractical.
This is why the OE use spring clamps. In an "Egg on Face" department, and
famous German manufacturer had to change from screw type clamps to spring
because of warranty leaks on California cars that were not brought into a
dealership every 3K miles for required service.
