Pliers for Small Engine Fuel Hoses

[Wamsutta]

What do you suggest for small hoses on lawn equipment? And are serrated jaws too harsh for the tender rubber hoses?

Hose size is 3.1mm I.D. x 5.7mm O.D.

Always wanted a silver bullet for these things. Curious if anyone has found one.

 

[dnschmidt]

Perhaps a small Pliers Wrench?

 

[tarmy]

Nope …just get new hose first…make a mess with gas for whatever you couldn’t get out. I usually **** the tank dry and then run the thing till it uses up what is in the hoses. Then cut, pull off or somehow work them loose and cut new ones to length. If your doing work on it may as well replace them and the filter while your there…only a couple bucks.

Since this doesn't come up often, I'd be inclined to "edit" an inexpensive pair of needle nose pliers to suit.

These work great or can get icon for more $, I also like the duckbill ones for the clamps, together makes a good set.

Not to dampen the enthusiams of replies, but re-readin the OP, seems he is asking for working range under 1/2 inch or 13mm

Hose size is 3.1mm I.D. x 5.7mm O.D.

I mention this because it seems the working ø range for standard hose clamp style pliers is something like 15-30mm. See, for example, this orbis extended reach hose pliers.



Also, it seems most of the pin-holding or bolt-holding style needle nose seem to have metal-gripping teeth, vs something suited to more fragile applications like flexible rubber type fuel lines and what not.

For other options, while you can certainly go to a 30 or 90˚ bent needle nose, question remains if that is the best option or not, given that the needle-nose-jaws can be a bit hit or miss for hoses in general.

 

[Fedwrench]

for small hoses, I like these NWS 147-62-205 pliers. They have thinner angled jaws with a smaller oval shaped opening for gripping small things. the opening is approx 1/4 of an inch.

Yeppers. What the world needs is this idea, only really small. I've never found anything like that.

I have and regularly use the larger hose pliers depicted in three sizes, but none of them go small enough for the eensy-weensy tubing found on smaller 2-cycle and 4-cycle engines.

I've never quite figured out whether it would be possible to heat up the tips of a small cheap pair of long-snoot pliers and modify them to grip a round thing. Might be worth a shot, and I suppose really cheap crappy pliers might be a little less likely to have problematic hardened jaws and teeth. Not sure about that.

My first thought was to break out the oxy-acet and custom bend some old long nose pliers. I don't think you would have to worry about heat treatment for this use case.

 

[theoldwizard1]

The Harbor Freight ones work for me ! 3 sizes. They don't stay shiny.

While you are there get the extra long needle nose pliers (the one with the slight curce) and the 90° ones also. Both are very handy when you are working on small engines.

Locate a pair of Tonsil forceps You can put some small tubing on the jaws if you feel that they are too traumatic

Locate a pair of Tonsil forceps You can put some small tubing on the jaws if you feel that they are too traumatic

Thats a good thought to put try some shrink-wrap on those...I wonder if they make a set with a small concavity in the jaws, that would be really nice option.

edit: maybe they do...These are (small) "bone grabbing" models

Verbrugge Bone Holding Forceps 13.5cm

Reda Bone Holding Forceps with an overall length of 13.5 cm are ideal for orthopedic and trauma surgeries that require secure bone manipulation.

I also like with these they "lock" without being fully closed, so you can hold various diameters securely.

 

[willf650]

I have those and they are too large for this application.

I bought these a few years ago and the small size works on my motorcycle fuel lines.
Titan hose pliers

I if the titan pliers don’t work I just use a pair of angled needle nose pliers.

 

[KnurledNut]

I find the needle nose ring pliers are often too thin and do more damage than good. But it the hose is that compromised, its probably better to replace it where possible.
I have used the Engineer screw extractor pliers. The tip is curved and fits small hoses well without having to completely encircle it. The tip is wide and the perpendicular jaw cavity grabs over barbs without being too aggressive to tear tubing. But they are short and need a straight on approach.

 

[OccupantRJ]

I use this for small hose removal, and a pair of duck bill pliers to install. I find that pushing hoses off works better than pulling.

 

[L.Cheapo]

I just use my fingers. If that doesn't work I reach for my Snap On seal removal tool set.

Snap-on Store

shop.snapon.com

If that doesn't work, the line gets cut because it's petrified and needs to be replaced anyway.

There is a set of Lisle pliers for this task. I have them, but I've never been able to get them to work in small engine applications:

That is what I use, forceps are a great tool to have in your tool box. I purchased a pair after I saw Chickanic (YouTube) use them for replacing fuel lines inside a chainsaw fuel tank, they are great for reaching through a small hole or space. HF has them so they are easy to find. Growing up my best friend's father was a doctor and he almost always carried a small pair in his shirt pocket. I don't know why because he didn't know one end of a screwdriver from the other.

There are about 1000 different varieties of forceps[1], many incredibly specialized for a specific surgical procedure. There's probably one shaped the way you want it, no matter what that is, but most of them are only available from medical instrument makers, at medical instrument prices.. The most widely used types are copied for all sorts of non-medical uses. I have 10 or 12 different kinds, mostly scattered around where they get used. Probably should have a couple more in the grabby tools drawer.

[1] I looked at a distributor catalog a few years ago, and there were about 5000 part numbers. There were lots of duplicate styes, but the variety really is staggering.

 

[javyLSU]

I've used this Gearwrench set for about 5 years and have been very happy with them - I've yet to damage any hoses I've worked on with them.

Hmmm. . . maybe he used it as a roach clip.

 

[four.cycle]

Unless I am mistaken, the smallest production-made pair of "hose grip pliers" is the 5047 ProAmerica (most likely made to the same dimensions as that "Gearwrench" model in post #24)
The model 5047 is billed as a " 5/16" " size, but I'm not sure exactly what they are measuring.
In any case, they are much larger than any hose you're going to find on a chainsaw (or lawnmower, for that matter.)
The ICON model posted above is also too large, as are the Knipex models shown above.

Which begs the question:
Why would a curved jaw pair of surgeon's forceps not work?
It's not like those hoses are torqued down to 90 foot pounds.

Very useful if you work on Japanese Motorcycles

Ditto on the mundane HF hose-tuggy set. I got this set maybe ten years ago, they don't look high quality, but they keep working for me. (No specific experience with small motor fuel hoses, though.)

The hose tuggy pliers made by Knipex and HF ICON, based on a 6" needle-nose pliers, are for larger hoses -- and very nice to have! But not for this job.

I grew up with a surgeon neighbor and his kids had a bunch of OR tools that they retired after showing some sign of wear or damage... they have to be perfect to stay in the OR.

I don't think they reuse equipment at hospitals anymore. You can ask to keep them after your surgery. I got mine after having stitches done on my finger.

I use these on small engine carb and fuel tank hoses that can't be pulled off with pliers. It pushes the hose off the fitting. Lisle LS47900
