1. Creating the Holder

Step 1

Open the fuel pump file in Maya which was saved in the previous part of the tutorial.

Step 2

To model the fuel nozzle, create a pPlane with Subdivisions Width as 4, Subdivisions Height as 6, Width as 1.5 and Height as 2. 

Step 3

With the five edges selected, go to Edit Mesh > Bevel and click on option box.

Step 4

In the Bevel Options window, keep the values of Width as 0.2000, Segments as 2. Click on Bevel button.

You can see the offset edges with the main edges.  

Step 5

With all in-between edges selected, go to Edit Mesh > Delete Edge/Vertex command.

Step 6

With the indicated faces selected, go to Edit Mesh > Extrude command.

Step 7

After applying the extrude command, drag the faces downwards a little bit. 

Step 8

With the left - right border edges selected, extrude these outwards a little bit.

Step 9

Follow the same procedure with the rest border edges also.

Step 10

Turn on Animation mode. With the mesh selected, go to Create Deformers > Nonlinear > Bend command.

Step 11

After applying the Bend deformer, you can see a wire object placed vertically.

Step 12

Rotate the wire in the 180 degree angle in X axis.

Step 13

Keep the Rotate Z value as 90 and Curvature as 2.2.

Step 14

After bending the poly mesh, go to Edit > Delete by Type > History command to delete the history.

Step 15

Place the pump holder model at the left side of the fuel pump.

Step 16

With the indicated edges selected, extrude and drag them up a little bit.

Step 17

Extrude the faces a little bit to add some thickness.

Step 18

Insert several supporting edges and edit them to complete the holder.

2. Modeling Bolt for Connecting Pump Holder

Step 1

In the Polygons mode, click on cylinder icon and create a small cylindrical shape in the viewport.

Step 2

Set the values of Subdivisions Axis as 6, Subdivisions Height as 1 and Subdivisions Caps as 2.

Step 3

Place this hexagonal nut at the indicated place.

Make another copy of the nut and place it at the other side as well.

3. Creating Hand Pump

Step 1

Create a polygon cylinder with the settings as shown under INPUT node in Channel Box/ Layer Editor. 

Step 2

With the cap faces of the cylinder selected, go to Edit Mesh > Extrude command.

Step 3

Scale up the extruded faces a bit outwards.

Step 4

Press F9 key for vertex selection mode. With the two indicated vertices selected, go to Edit Mesh > Merge command to weld the selected vertices.

Step 5

Following the same procedure, select and weld each two alternate vertices together as shown in the following image.

Step 6

Merge the triangular faces also.

Step 7

For reducing the unwanted edges, select every alternate edges and delete them all. 

Step 8

With all cap faces selected, extrude once.

Step 9

Keep extruding and editing the faces to get something like this.

Step 10

Insert an edge loop as shown in the following image.

Step 11

Following the same way, insert edge loops around all triangular faces. 

Step 12

To make the hand grip better, insert several more edge loops around the hand grip area.

4. Creating Fuel Controller Chamber

Step 1

For modeling the fuel controller chamber, duplicate the grip model polygon mesh and rotate it about 80 degree as shown in the following image.

Step 2

Select the rig faces as shown in the following image.

Step 3

Extrude and scale down the selected faces. 

Step 4

Extrude the same faces once more and edit the edges as indicated in the image below.

Step 5

Select and delete the bottom faces of the mesh.

Step 6

With the border edges selected, extrude and scale down a bit as shown in the following image.

Step 7

Keep extruding and editing the edges until you get the shape as shown below. With the last border edges selected, go to Mesh > Fill Hole command to fill the empty space.

Step 8

Insert two edge loops as indicated in the image below.

Step 9

With the indicated face loop selected, extrude and scale down a little bit.

5. Finishing Hand Pump Section

Step 1

After finishing the fuel controller chamber, it’s time to complete the hand pump section. With the handle grip polygon mesh selected, go to Show > Isolate Select > View Selected and turn on the check box.

Step 2

Rotate the indicated border vertices around 25 degree in X axis. 

Step 3

With the cap faces selected, go to Edit Mesh > Extrude command to extrude the selected faces.

Step 4

Keep extruding and sculpting the shape as shown in the following image.

Step 5

Unhide the hidden meshes, so you could model the objects seeing all parts of the mesh. 

Step 6

Extrude thrice the end part of the object to make it like the injector pipe holder.

Step 7

The hand pump section is completed now. 

6. Creating Handle and Trigger

Step 1

Create a polycube.

Step 2

Extrude the top and bottom faces as shown in the following image.

Step 3

Keep extruding and editing the bottom face and form the indicated shape as shown in the following image.

Step 4

Select the inner faces.

Step 5

Extrude and scale down the faces a little bit.

With the indicated faces selected, press G key to repeat the previous extrude command.

Step 6

Select a face as indicated in the image.

Step 7

Extrude the selected face thrice.

Step 8

Continue extruding and editing the face to make it as a trigger as shown in the following image.

Step 9

To add details, select the two faces at either sides and extrude a little bit.

7. Suspension Spring Modeling

Step 1

Go to Create > Polygon Primitives > Helix command.

Step 2

Set the parameters of the helix as shown in the INPUTS channels. Place the helix shape around the pipe as shown in the following image.

Step 3

With the all hand pump parts selected, go to Edit > Group command to make a group of the selected meshes.

Step 4

After making the group, go to Modify > Center Pivot command to center the pivot of the grouped object. 

Step 5

Put this hand pump model inside the pump holder. 

8. Creating Rubber Pipe Connector

Step 1

Create a polygon cylinder in the side view.

Step 2

Keep the values of Subdivision Axis as 16, Subdivision Height as 1 and Subdivision Caps as 3.

Step 3

With each alternate central edges selected, press Delete key to delete them all.

Step 4

With the indicated faces selected, go to Edit Mesh > Extrude command to extrude selected faces.

Step 5

Keep extruding and editing the faces to make something like this.

Step 6

Go to Create > CV Curve Tool and click on its options box. In the Tool Settings window, turn on 3 Cubic radio button.

Step 7

In the front view, start creating the curve from the rubber pipe connecter to downwards.

Step 8

Complete drawing the curve line for the rubber pipe model as shown in the following image.

Step 9

Edit and arrange the vertices of the pipe something like this. 

Step 10

First select the indicated faces of the rubber connector and then with pressing Shift key, select the CV curve also. Go to Edit Mesh > Extrude command.

Step 11

At first, it will only extrude the mesh from start to end. You need to increase the extrude subdivisions.

Step 12

With the extruded mesh selected, go to INPUT section and increase the Divisions to 75. 

Step 13

You might have to edit the starting part of the pipe to make it look better. 

Step 14

Create a small cylinder with Subdivision Axis as 6.

Step 15

Put this nut object above the base plate as shown in the following image. 

Step 16

Do it for all corners of the base plate.  

Step 17

The fuel pump modeling is completed now. In the next part, I will start unwrapping UVs for texture map. 

The wireframe look.

Conclusion

The modeling of the fuel pump is done. I hope you must have enjoyed the modeling session. In the next part of the tutorial, I’ll start unwrapping.
