Welcome to Diesel Update

We create modern engine parts for antique diesel vehicles. Our first product is a compression test adapter for the direct-injected Toyota 13B and 13BT engines usually referenced as SST 09992-00023 Gauge Adapter by the Factory Service Manual.

We're working on a VGT turbo controller, solid state glowplug controller, EDIC relay replacement and more.
Designed and machined in Maine, USA.
