Runs fine just putting around the yard. Get it out on the road and about a half miles it runs out of gas. Let it idle for a few minutes and it will run for another half mile and do it again. Replaced both fuel pumps and filter. Does anyone know if I can get rid of the factory fuel pump?

Hi All,
I have a 14 mile round trip on level roads to reach the property where I work with my 2025 Amp Crew Ranch (purchased, April 2026). That 14 mile round trip uses 60% of the battery as shown on the gage for a calculated range of 23.3 miles versus an advertised “up to 50 miles” range. A mile or two working on the property gets me a flashing gage and warning beeping by the time I get home. The dealer was good to work with and even with a new battery (yesterday) the results were about the same, although there seemed to be more power and a higher top speed. I own a Mach-e Mustang so I am familiar with how various conditions affect range, but less than 50% of advertised range just seems like there has to be something out of whack.
Now I’m wondering if there is a controller and/or software issue affecting the range and performance. At various points the Amp seems to lose power for no reason and then has trouble maintaining speed. Any ideas?
Also, twice now, the brakes seem to have not released fully. After noticing reduced speed, I stopped and check the rotors and wheel…..HOT! So, now every time I feel less power, I stopped to cycle the brakes and check the temperature. Very annoying. Are there any adjustments to be had?
And yes, as noted in another post, sometimes the switching from forward to reverse or high to low speed feels sluggish or balky.
Lastly, while an electric vehicle powertrain is quiet, my Amp was horrible from a road noise and vibration standpoint. This was easily fixed by locating panels vibrating on other panels or the frame (even the cup holders were vibrating) and installing felt adhesive pads at the contact points (seat to frame, windshield to frame, fenders to frame, etc.). This is a $10 and 1/2 hour fix that makes a significant improvement in the driver/passenger experience. Tire noise, yes, but that’s because of the knobby tread.
I’m trying hard to like my Amp and would appreciate any tips, advice or solutions.

Just received delivery of a 2024 AMP Pro. Thought I'd start a thread with my impressions as I use it and learn more. There doesn't seem to be a whole lot of real-world usage information out there on this model. Hope this will help others as they research.
Intended Use Cases
Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property. The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion. Wasn't an original use case, but a nice added bonus. Experiences So Far
Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing. The metal on metal contact has damaged the powder coating and the frame. I expect a little better QC.
I've only put a few hours on it, so not a ton to report on usage. It isn't quiet; it's silent. I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller. The motor controller is Italian and made by Dana TM4. Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent). The motor is rated at 25 hp and 71.5 lb-ft of torque. It feels very powerful. All the torque is delivered instantly, if desired.
The bed is huge and has an electric dump as standard. Great feature but would like it to go up a bit more. Probably not feasible from an engineering perspective, but I want and I need ;).
Power steering is nice, but vague. Probably common to many UTVs, but I am accustomed to more direct results from input. Plan early and plan often.
In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart. I may get fatter, but I'll also get more done. After a few days of usage, the battery meter has gone down by 1/10th.
Until next time...

After three years, my Sector completely died. Something caused the hot wire under the seat from the charger to disintegrate, so the batteries weren't being charged. The batteries weren't charging 100% anymore, so decided to convert to lithium.
As most others have done, I went with 4-48v batteries in parallel, as I believe that will be plenty of amp-hours for my needs, but can always add more if needed. I went with LiTime wired CAN batteries and mounted their digital gauge on the dash above the current one, which fit perfectly. I didn't think the existing battery brackets worked well for the new batteries, so made my own out of aluminum L rails, which makes it much more secure (and saves a few more ounces :)). Since I wired them in a 'balanced' configuration, I had to make all new cables from 0/1 gauge wire and 8mm posts. I updated the DeltaQ charger to profile 233. Cleaned everything up (I must have vacuumed 20 pounds of dirt!), put it all together and... wham!
So far, it definitely is better than with the original AGM batteries. Sustains speed better going up hills, and seems to have plenty of reserve current. The difference in weight with 4 LiPo vs 8 AGM batteries surely doesn't hurt!
Thanks to everyone on this forum, but special shoutout to GNFO who was a big help.
A few questions:
In the 'any tips' thread, EVSupport mentioned reprogramming the Sevcon to reflect the new discharge curve of the lithium cells, but I didn't see any more info about that or how to do that. Is there any more info about that?
Have folks replaced the onboard 12v battery, and if so, with lithium? I'm not sure why there is a 12v battery; why didn't they just step down the current of the 48v system to provide power to accessories?
Is there a recommendation as far as charging with the lithium conversion? As far as I understand, it is better to let lithium batteries discharge somewhat (but not completely) than keep them charging all the time. What do you think?

ABSOLUTELY THE WORST EXPERIENCE EVER!!!!!
I purchased a Massimo Motors Warrior 700 UTV directly through the company. This unit was listed for sale on Ebay as a company demo with only 77 miles. Prior to bidding on the item, I messaged them through EBay and asked if there was "anything wrong with it and if everything worked properly". I was assured in writing that everything on the UTV was operational AND that it would be inspected before shipping. I also called the number that was in the EBay listing to verify that everything was operational and to make sure the item could be delivered to my land in Missouri. I made it VERY clear that I was not interested in bidding on the item if those two things were not acceptable. I was assured over the phone that everything was operational, that it would be inspected prior to shipping and that delivery to my land in Missouri was perfectly fine.
It was not delivered to the address agreed to by their contact listed in the EBay listing. And when it was received, there were multiple items that were not operational. Items that were defective when it arrived include a headlight, a backup light, both horns, the horn wiring and the parking brake. They refused to even supply me with replacements for all the defective parts. In response to the BBB, Dave said it was sold without a warrantee. The listing very clearly stated 180 day warrantee for parts.
In addition, the windshield that was clearly shown on many photos on the listing was not delivered with the UTV. That's correct...THEY STOLE THE WINDSHIELD before shipping the unit to me. The first representative from Massimo Motors told me multiple times that “the company will make things right for me”. He did supply me with a couple parts; which I installed myself. Later, he told me that he is no longer with the company. Dave, the new contact never offered any reasonable solution to any of the remaining issues.
His solution to STEALING THE WINDSHIELD was for me to fabricate one myself.
Unbelievable experience. See files attached.
Hope this helps others from making a BIG MISTAKE.
See photos attached for proof.
If this help, please let my “buddy” at Massimo know why you aren’t buying one. Here’s his info:
