Holman 20 hose reel?

Add a loop to the reel for more tension or remove a loop for less tension. Similar to the way it is done in the open reel in the video https://youtu.be/pyIaVfZ67RA

If the hose will not recoil when you pull on it slightly, Inspect the spring that coils the hose. It could be broken or out of position.

It goes down under the tension arm and between capstan and Pinch roller under next tension arm and into the reel.

The Booklet says "if the hose retraction wheel is stuck and the hose is fully extended, the wheel still have movement. Grip the hose close to the guide hole and gently pull.
The retraction wheel will give you enough movement to unlock itself before you slowly allow the auto retraction wheel to wind the hose back into the unit."
They also say when walking the hose back to the unit, turn the tap off and press the lever on the watering gun to release pressure on the hose. This makes the retraction to the hose reel a lot easier and prolongs the life of your hose reel.

Need more info. Is it a hose or a belt that lost tension? By reeler do you mean tensioner?

If the problem with your Frontgate retractable how is that it simply won't retract, on the assumption that the hose hasn't gotten off the coiling wheel and become tangled, and that there isn't a problem with the hose distributor - which runs off a rubber drive belt, or some other mechanical problem, it is possible to re-tension the spring on a retractable hose.

The principle of these retractable hoses is similar to the energy that is stored in the spring when you pull the starting cord on your lawn mower - which then retracts the cord when you release the pull handle. With the hose completely recoiled, using the blade of a screw driver, you can pry off the triangular cover on the left-hand side of the unit. You'll note four Phillips head screws which secure the round, black, plastic plate to the body of the caddy. If the tension is already "out" of the spring you can remove these screws and nothing will happen. If there is some residual tension remaining, the plastic plate may rotate clockwise a couple of turns when the last screw is removed (it won't spin like an airplane propeller, so don't worry . . .).

To re-tension the spring, I used a crescent wrench and opened the jaws so that the width matched the gap between the two slots you'll see in the plastic plate, and inserted the wrench into the two slots (the wrench will be at a right angle to the plate, at this point. Then, while holding the crescent wrench in place, I used a metal bar, and inserted it through the hole at the other end of the wrench (for better leverage), and turned the plastic plate counter-clockwise five full turns. Then, while keeping the tension on the plastic plate, re-insert all four Phillips head screws, and fully re-secured the plastic plate.

If the inner spring isn't damaged, this should restore the tensioning to the hose reel, as the spring will be further tensioned then automatically, as the hose is uncoiled - which will then be the stored energy that recoils the hose.

Where can I get a replacement tension spring for my auto reel hoselock 2490 ? I have tried everywhere but without success. Any help is much appreciated

Simple, take off the hose and wind up the reel to the desired tension, replace hose and your good to go!

Unreel the hose all the way out. Unscrew brass fitting at reel. Screw on new hose with fitting tape. reel up new hose. You're done. Good luck.

You may have to take this one in. It is an inertia reel and is made to retain tension at all times, if you relieved the tension, reel is "sprung" and will have to be completely disassembled, in some accidents if the seat belt is used in the impact and impact is severe enough, inertia reel has done its intended job and needs to be replace entirely.
