Find your size
The right siphon comes down to one thing: what fits your filler neck. Tap what you're fueling (or draining) and we'll point you to the right one.
What are you fueling or draining?
Compare all three sizes
| Size | Flow rate | Lengths | Best for | Price |
|---|---|---|---|---|
| ½" ID | Up to 4 GPM | 6' or 8' | Jet skis, pontoons, ATVs, dirt bikes, mowers, small engines | From $8.95 |
| ¾" ID | Up to 7 GPM | 8' | Pontoons, larger PWC, UTVs — most restricted filler necks | $34.95 |
| 1" ID | Up to 10 GPM | 6' or 10' | Wakeboard & ski boats, hot tubs, big tanks, water transfer | From $39.95 |
The one rule of thumb
Small filler necks need small nozzles. Jet skis and most pontoons can't take a 1″ nozzle — go ½″ or ¾″. Most wakeboard and ski boats, hot tubs, and open tanks happily take the full 1″ and its 10 GPM flow. Still not sure? Ask us — we answer fast.
