7.3idi: WVO and glow plugs

[sieg01]

Are there any glow plug recommendations with WVO usage?

I am currently converting my '94 van towards WVO.
On German WVO user/supplier pages, you can read, that longer glow plugs are used to support the engine starting process. Especially during winter time.

Are there any other "longer" glow plugs available or are there any "dedicated" WVO glow plugs for our engine?
In this moment I have Beru/Motocraft ZD9 and one AC Delco 32G (https://www.oilburners.net/threads/diy-glow-plug-harness-no-wait-to-start-light.91399/post-1104588) and I believe it could be better...

Thanks.

ZD9s are fine.

ZD9s are fine.

Sadly, I can not share your experience.
That's why this is now happening: https://www.oilburners.net/threads/special-designed-wvo-glow-plugs-for-7-3idi.92160/
