Q: what parts and fittings come with the pump
3 months ago1 Answer
- AI-generated, Human-approvedA: This pump includes quick-attach port fittings and an in-line fuse. Reviewers have noted that the included fittings are straight-through connectors, though some users found they needed additional 90-degree elbow fittings for their specific setups.3 months agoHelpful?
Q: Is the mounting bracket compatible with the dumbo 2.4 gonna pump?
3 months ago2 Answers
- AI-generated, Human-approvedA: Yes, this 4.5 GPM pump is a suitable replacement for 2.4 GPM models and is compatible with Fimco systems. It uses the same Quick Connect ports for straightforward installation, though you may need a new manifold to mount it to your tank if you are swapping from a smaller pump.3 months agoHelpful?
Q: I currently have 2.4gpm pn 5281371. Will this pump be a good fit on my FIMCO 60g sprayer?
3 months ago2 Answers
- A: The 4.5 GPM High-Flo pump is a great performance upgrade for your 60-gallon sprayer. This unit uses the same Quick Connect ports as most FIMCO systems, making physical installation straightforward, but always double-check your current hose configuration to ensure a secure, leak-free fit. It is also helpful to know what to expect regarding your spray patterns once the pump is installed: Spray Gun Performance: While the 4.5 GPM pump provides more volume, the horizontal spray distance will remain largely the same. You may see a slight increase in vertical reach—roughly an additional foot—due to the higher volume available, but the overall spray pattern will remain consistent with what you are used to. Boom Spray Setup: Please note that the upgrade will not change the spray performance of your current boom setup. The spray pattern and output from your boom are dictated by the nozzle tips currently installed on the boom. Since the pump is a demand-style unit, it will simply maintain the pressure required by those existing tips without forcing extra fluid through them.3 months agoHelpful?
Q: Draw depth
7 months ago1 Answer
- A: Hi thanks for the question, the Fimco 12V High-Flo High-Performance Pump, 4.5 GPM has a "draw depth" or maximum suction lift of up to 14 feet.7 months agoHelpful?

Q: Can it spray diesel?

- A: No, you can not spray any petroleum products through the pump.a year agoHelpful?
Q: Is this pump compatible with acetuc acid /vinegar at herbicide concentrations
a year ago1 Answer
- A: No, it is not recommended to use those through the pumps, as they are hard on the check valves in the pumps.a year agoHelpful?
Q: Need an inexpensive wand for this pump???
a year ago1 Answer
- A: Please contact our customer service team at 800-831-0027 and they'll be happy to assist you with a spray wand.a year agoHelpful?
Q: How far can it spray
a year ago1 Answer
- A: if you're using our deluxe pistol grip spray gun, you would achieve approximately 28' vertical throw and a 40' horizontal throw.a year agoHelpful?
Q: Will this replace model # 5277981? Trying to increase my output pressure
a year ago1 Answer
- A: Kirk, the 5277981 is the old 2.1 GPM pump with a 60 PSI rating. The 4.5 GPM also has a 60 PSI rating. You're not going to gain anything pressure wise going to the larger pump. Expense wise, you're probably going to be better off with the 2.4 GPM pump that has replaced the older 2.1, it also has a 60 PSI rating.a year agoHelpful?

poor performance

Tractor Supply needs to take this pump off the shelves. I've had to replace this pump 3 times in the last month thinking no way its the pump. I then test the pump off of the equ.. an no power at all or it has half the power. I went yesterday afternoon to replace the one that went bad Monday. I put the replacement pump on this morning, it last me a hour an its out.Today 8/27/25 I'll have to take this one back. I'd rather get my money back an go with a different brand.

Absolute Junk
a year ago
Would give it no stars if it was an option. Absolutely junk. I contacted customer service and got told it was the surfactant that was included in the roundup that caused the issue. I guess if all you’re going to spray is clean water it will probably work fine. If you plan to actually use it don’t buy it. Can’t believe they can get $1000.00 dollars for a sprayer with this pump thats no more than a water tank.

Fimco Industries
Sorry you had that issue. I do hope our customer service team took care of you without any issues, as we stand behind our products. Yes, chemicals with petroleum distillates and surfactants can cause issues with the check valve in the pump, as surfactants are a sticking additive and can cause the valves to stick a little.

I like the motors but they don't last me very long. I really wish I could learn how to work on them. This is my 4th or 5th one to buy. At first I had the smaller one that came with my 40 gallon tank but after using 2 I went to the bigger one's. The one I am replacing now the motor won't shut off I have to turn it off with the switch. I water a lot of flowers for our town which is my job. I just wear them out I guess.

Ruth, thank you for your purchase of the 4.5 GPM pump from Tractor Supply. Please contact our customer service team at 800-831-0027, as it's probably only the check valve inside the pump that is needing to be changed, as the check valve is the part responsible for building pressure and pumping your solution through the lines. they will be happy to assist you troubleshooting and get you whatever part is necessary to get your pump back to expected operating pressures.

Nice Pump...but

I used this pump as a replacement in my Holiday Rambler motor coach. It was half the cost of an "RV" OEM pump. The bayonet fittings made installation easy. BUT, it only lasted a year. I had purchased a 2 year warranty with Harbor Freight and they replaced it. I hope this one lasts longer.

Great when it works.
2 years ago
This pump works well when it is working. We have replaced it twice within the last three months under the warranty. The first time it just stopped working with no noise. The second time, it sounded like it was working, but did not pump. We upgraded the last time to a larger pump. For context, we do use the pump multiple times a day as we have a drone spray business and this is on one of our tanks.

Take the warranty. You never know how long it's going to last. I've had some go 2 years and some 30 days. you never know. Flush with clean water before prolonged set up. Cycle some RV antifreeze at winterizing, let it supply and return to the same jug and cut it off. Never ever use Diquat / Paraquat through one, its death to them even on short term use.
