Wiring diagram

How the Revolution 4008 is wired.

Open this example in Crimp to use your own parts and cable lengths. Review the assumptions and installation notes as you adapt the circuit.

Shurflo Revolution 4008 wiring example with 3 components: House bank, Fused DC distribution, Revolution 4008. 4 cable connections. Crossings are not junctions.Red = positive · dark = return · dashed = signal. Wire sizes and fuse ratings are example values; use the equipment instructions and actual installation lengths.

This is the 12 V Revolution 4008-101-E65. The starter uses Pentair's recommended 10 A fuse and sizes the supply from the published 7.5 A maximum running current. Startup current and duration are not published here; the fuse rating is not a surge-current specification. Verify the actual run and pressure-switch installation. Manufacturer installation manual

Cable sizing for this example

Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.

3 m one way

12 V system

Wire: 2.5 mm² · 13 AWG
Example fuse: 10 A
Design current: 7.5 A
Voltage drop: 2.7%

Sized against ABYC E-11. The design current is the part's continuous draw. The length is one way; voltage drop includes an equal-length return.

Run-length and manufacturer assumptions

The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.

Supporting parts

6.1 m total of 2.5 mm² (13 AWG) marine cable
Terminations for 2.5 mm² cable, matched to the equipment's screw terminals, leads or studs
10 A fuse and holder on the positive run
Heat-shrink, strain relief and terminal boots sized to the cable

Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.

Which Shurflo Revolution 4008 is this?

This entry is Shurflo Revolution 4008-101-E65, the 12 V aftermarket RV freshwater pump. Pentair pairs it with OEM model 4008-101-A65 in its Revolution product table. Aqua King II is a different product family.

How is the Shurflo Revolution 4008 wired?

Pentair lists 7.5 A maximum running current and recommends a 10 A fuse. The red lead is positive; black is negative. Operating current changes with pressure.

The editable example uses that running-current limit and pins the recommended fuse. Its cable calculation depends on the complete supply and return run. Adapt the lengths to your installation and choose the actual fuse and holder.

What should I bear in mind with the Shurflo Revolution 4008?

The 10 A fuse recommendation is not a published startup-current measurement. The cited data sheet does not supply a startup current or duration. Pressure-switch behavior and the plumbing system remain outside the electrical model.

What do owners and installers say about the Shurflo Revolution 4008?

In an Airstream owner's replacement-pump report, a new 4008-101-A65 runs but produces little water. Indexed replies suggest checking the inlet and strainer seals. No confirmed resolution was available in the reviewed excerpt; the report illustrates why an operating motor alone does not establish that the plumbing works.

What belongs around the Shurflo Revolution 4008?

The pump needs a protected positive feed and negative return. Use the wire size calculator to examine a different run before adapting the starter, and follow Pentair's instructions for the strainer, plumbing and mounting.

Fit check

Connect it to the rest of your system.

Describe your setup to draft a system with 4008-101-E65 connected. Review the selected parts and cable lengths, then edit the diagram in Crimp.

The model only picks parts and draws the connections. Every wire size and fuse rating still comes from Crimp's own sizing, never from the model.

Sources and sizing method

Equipment specifications. Model details, ratings and terminal roles come from the catalog. Check your unit’s label and current manufacturer documentation for its exact revision.

Example sizing. Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. Results use the example current and run length shown above. Set your actual equipment, lengths and installation conditions in Crimp before choosing hardware.
