Fuel injection hose clamps

[Wasted youth]

Those crimp clamps sure are nice... I used a bunch of those, too. Then regretted it in several places. In a jam, (roadside repair, etc.) you will have to have a nice pair of dikes to cut them if you need to change something like a fuel filter, or remove an injector.

Then, you will need to have another clamp to replace the one you just cut. Hopefully, when you cut it, you didn't nick the hose. The proper tool for those clamps is a nice investment, too.

They are tougher than you think, and you will need to be able to have the leverage and strength of your hand in an awkward position. If you choose to keep using them, at least make one half of the arrangement with a removable clamp.

You will not be able to tighten the crimped clamps as the hose ages and the connection gets loose the way you might need to with a screwed clamp.

And finally...

I am mystified why you cannot find the fuel injection hose clamps. When I got my Gates hose from O'Reilly's, I got a box of the nice FI clamps.

If you are concerned about the large serrated hose clamps cutting into hose, wrap a trimmed, short piece of aluminum sheet from a beer can around the hose under the serrated clamp. It is thin and soft enough not to impede the strength of the clamp, but also good enough to prevent the clamp from gouging the hose. You can tighten the shit out of it with a 1/4" drive socket.

Yeah. I could see a roadside repair being a pain. I'd definitely prefer to have the proper FI style clamps for this larger 20mm OD non-FI hose, but they don't carry it at any auto parts store I've been to. I've got a bag full of regular FI clamps for the 7mm FI hose. Those are easy to find.

These do come off if you wedge a screw driver under the clip, but would still be tricky to do on your back under the bus.

Normally it takes a screwdriver to remove a screw on clamp. When you have a crimped clamp used the screwdriver sideways thru the crimped area and wiggle it side to side. The crimp will open up allowing one to remove the clamp. When done just re-crimp the connection. Most of these crimp style clamps will work multiple times.

Thanks for posting a picture of scewdrivers, Steve!

I argue the prefered tool for hose clamps is either a nutdriver or 1/4 inch drive ratchet socket, but that really is not the point. If you are using screwdrivers on hoseclamps, get ready for it to slip out when you do the final torque. If the clamp is not designed for socket head tools, it is probably old. Enjoy using old hose clamps with worn threads! You might get lucky and it stays put.

Anyway, I see the clamps you are referrring to are not what I used; The clamps I use are solid piece, and thicker steel. They get crimped on either side having two ears and are custom for the hose size, not like those pictured where it has some adjustment. The clamp style in this last picture I have seen on CV joint boots, and other locations.

But I don't agree that even those in the above picture should be re-used... ever. That crush crimp is not designed for re-use. You could do it if you had to, but expect it to be not as strong.

The 18-20mm fuel hose clamps seem to be widely available in Europe. In the UK they refer to them as "Petrol Pipe Clips". May order a few of these to have on hand for my next fuel filter change.

Picked up some of those 18-20mm FI style clamps from the UK. They fit great and are nickel plated. I've got some extras if anyone wants a pair. I'll send them anywhere in the US if you pay postage. PM me if interested.

I originally posted the quoted area today in type 3 thread on Oetiker clamps. Needs to be here too for FI buses.

I used both on my build. I used removable ones that would allow for the whole assembly of something to be removed and oetiker on anything that wouldn’t need to be removed.
