looking for a diesel fuel vacume gage and o-rings for firewall

[haryv]

Doing some mods to the truck looking to add a fuel vacume gage to the diesel line if anyone can recomend any. Also, looking for a large dial white water temp gage with perhaps a trip circuit that will blink if there is a over temp.
Lastly looking for though the firewall rubber sealing disk if thats what thay are called. Orings are nice but do thay do the best job keeping water out of the vehicle? Need a place that sells them close to Delta BC.

Try Autometer website. See what they offer.

What is the fuel vacuum gauge used for? To see a restiction in the filters? To see how hard the injection pump is pulling?

What would the info be used for?

The vacuum gage doesn't work for a deisel like it does for gas! A diesel has NO vacuum.

there are diesel vacume gages for boats.

Its is for anyone who runs wvo and wants to see if the fuel system is plugged. not a absolute nessesity but very helpfull to see where the restriction is and when its time to change the filter
