Editing Z31/vacuum lines php (section)

== Z31 Vacuum Line Replacement ==

To replace all the applicable engine lines (including all '''vacuum''' and
'''coolant''' lines), you will want to order the following lengths.
If you are not replacing certain sections, simply subtract the noted lengths and diameters
from the total in the ''"kit"''.

Important: These lengths are based on the rerouting modifications I have made on my car. Each measurement is slightly overestimated, and totals are rounded up to the nearest foot. This means you’ll have a little left over from each hose length.

Since hoses are sold by the foot, expect to end up with a few extra inches of material—
which is helpful as a backup. If you want to replace the
'''vacuum tank through firewall hose''', be sure to
add about 6 feet to your order.

=== Order Needed (Modified Lengths) ===

| Hose Size | Exact Length | Order Amount | Notes |
|---|---|---|---|
| 3mm | 116" | 10 ft | Base replacement |
| 4mm | 165.5" | 14 ft | Base replacement |
| 6mm | 103.5" | 9 ft | May require 10 ft minimum order |
| 10mm | 56" | 5 ft | Replaces brake booster hose (stock is formed) |
| 3/16" Clear Vinyl | 14" | 2 ft | Available at Home Depot |

'''Note:''' Does not include vacuum tank through firewall hose (~6 ft) or vacuum hoses inside the car (A/C controls).
