Twenty-three horsepower from a Vanguard V-Twin drives the FNG-23V, a Franklin Electric gas engine driven centrifugal pump that needs no power line at all. At the other end sits the FACGF-5H, a 2-inch pump on a 160 cc Honda. This page lines up the FACGF, FNG-23V, and FTSP by engine, port size, and priming.
Each pump here mounts its pump end directly to the engine. That keeps every unit compact enough for a skid, trailer, or truck bed.
FACGF, FNG-23V, or FTSP: Pick by the Job
Choose the FACGF for light to medium portable jobs with clean water and 2-inch hose. Choose the FNG-23V when you need a 23 HP engine, electric start, and a 3-inch suction for water truck or large irrigation work. Choose the FTSP when the pump must prime itself or pass solids.
Three Series, Three Kinds of Work
FACGF Series: Compact and Simple
The FACGF pairs a cast iron volute with an enclosed cast iron impeller, which builds good pressure in clean water. Its carbon/ceramic seal uses FKM elastomers, and every engine has an adjustable throttle. Pick the engine brand your mechanic already services.
FNG-23V Vanguard V-Twin Gas Engine Pump
The FNG-23V is a close-coupled, end suction pump built around a 23 HP Vanguard V-Twin with cast iron cylinder sleeves. It adds a replaceable bronze wear ring, a self-lubricating Type 21 seal, and a low oil pressure switch (warning light not included).
FTSP Series Self-Priming Engine Pump
The FTSP is listed here as a gas engine centrifugal pump, but it primes itself. A check valve in its removable front cover holds water between starts, and a two-vane semi-open impeller passes spherical solids. Franklin rates the series up to 615 GPM and up to 100 feet of head.

| Model | Engine | Engine size | Suction x discharge | Self-priming |
|---|---|---|---|---|
| FACGF-5 | Briggs and Stratton | 205 cc | 2 in x 2 in | No |
| FACGF-5H | Honda | 160 cc | 2 in x 2 in | No |
| FACGF-8H | Honda | 270 cc | 2 in x 2 in | No |
| FACGF-23K | Kohler | 728 cc | 2.5 in x 2.5 in | No |
| FNG-23VM | Briggs and Stratton Vanguard V-Twin, 23 HP | 627 cc | 3 in x 2.5 in | No |
| FTSP-2HRF | Honda, roll frame | 160 cc | 2 in x 2 in | Yes |
| FTSP-3HRF | Honda, roll frame | 270 cc | 3 in x 3 in | Yes |
| FTSP-3DRF-ES | Kohler diesel, roll frame, electric start | 442 cc | 3 in x 3 in | Yes |
| FTSP4-18V | Briggs and Stratton Vanguard, electric start | 570 cc | 4 in x 4 in | Yes |
Electric start models ship without the battery and cables, so plan to add them before the first start.
Five Checks for Lift, Hose, and Fuel
- Measure your lift. If the water sits below the pump and you restart often, lean toward the FTSP or a foot valve.
- Know your flow and head. Add up the vertical rise, hose length, and any spray or nozzle pressure.
- Match your hose. Port size limits flow, so do not choke a 3-inch pump with 2-inch hose.
- Plan the run time. Bigger engines use more fuel, and FTSP fuel tanks range from 0.8 to 2.2 gallons.
- Pick the engine brand. Choose the one your local dealer can service.
Dirty Water, or a Drive You Already Own?
If most of your jobs involve dirty water, high suction lift, or constant restarts, the FMIG, FNSGF, and FBSGF pumps on our gas engine self-priming page are built around that job.
If you already own an engine, tractor PTO, or belt drive, a bare frame mount centrifugal pump may be the better buy. To compare every engine powered option side by side, go back to our engine driven pump overview.
Engine Size Drives the Price
A FACGF-5H with a 160 cc Honda costs far less than an FNG-23V with a 23 HP V-Twin. Electric start, roll frames, and larger ports add to the cost, and we quote each exact model.
Frequently Asked Questions
How do you use a gas engine water pump?
To use a gas engine water pump, set it level on firm ground and keep the suction hose short, with a foot valve on the FACGF or FNG-23V. Fill the pump housing with water before the first start; the FTSP then holds its own prime. Start at low throttle, raise it once water flows, and never run the pump dry. Add a check valve on the discharge, and on electric start models, connect a battery first.
Should I buy an electric start gas water pump?
You should buy an electric start gas water pump if you restart the engine many times a day or run a large engine that is hard to pull over. In this category, the FNG-23V, FTSP-3DRF-ES, and FTSP4-18V have electric start. Each ships without the battery and cables, so budget for both. The smaller FACGF-5 and FACGF-5H use a recoil pull start, which keeps them simple and battery-free.
What does low oil shutdown do on a water pump engine?
Low oil shutdown stops a water pump engine when its oil level drops too low, before the engine can seize. That matters on long runs when nobody is watching. The FTSP-2HRF, FTSP-3HRF, and FTSP-3DRF-ES have low oil shutdown, and the FTSP4-18V does not. The FNG-23V has a low oil pressure switch that triggers an alert, but the warning light is not included. Wire one in before unattended use.
