VDO Gauge Swap "master list"

Can anyone provide a list of all the part numbers and sending units needed to do a complete swap out of the stock gauges to VDO. I spent a couple of hours last night zig zagging between threads, but many part numbers ended up contradicting others, or don't call for which sending units are required, and which are not.

It seems the adjustable speedo is: 437 155
Fuel Gauge: 301 105 (but don't know which sending unit, if gaskets are needed...)
Temp Gauge: 310 105 (but sending unit is different in FAQ then in another thread)
etc.

Figured it would be nice to have them all in 1 nice long list - then again - I probably missed it and am gonna feel like an idiot when someone posts a link to it.


Thanks so much in advance for any help!!

-Aaron

There's already several lists, slightly different depending on year of vehicle. Search for: VDO Gauge parts/installation/problems merged threads.

Speedo: Yes, for MPH. You might need a sender depending on if your truck has one or not.
Fuel gauge: Yes, it uses the stock sender. Just install the gauge in place of the old one.
Coolant temp: Yes, for Farenheit. Sender depends on which engine you have and whether you want a high temperature light as well.

So basically, it seems the only sender you need (for a 97) is for the temp gauge. Now the only problem seems to be that I've come up with 2 possibilities for the temp sender: 323 095 or 323 417 Anyone know the correct sender for the 97's?

Also, with respect to the jumping fuel gauge needle on the oem gauges... is this fixable at all? - will replacing the gauge to the VDO fuel help, changing the sender help, or no such luck and just quit whining?

Some gauges are made with signal dampers ... I don't think the VDO is ... Quit whining is probably the cheapest option.

Jumping needle? The VDO gauges are dampened. The stock gauges are dampened more.... You can decide if that is good or bad.

I'm pretty sure the V8s use 1/8" NPT so the 323-095

Jumping is more like dropping down a quarter tank, then flicking back up... All well and fine until I end up at a quarter tank or less... then it's russian roulette with how much fuel is left in the tank. Just wasn't sure if changing the sending unit would fix this, or if there is something more to it. From what I remember reading a while back, it seems to be more prevalent in the '97's

For the temp sender, think I might go with gauge that is 310 1052. It comes with the 1/8 NPT, as well as a couple of metric adapter bushings - happens to cover the 323 417 option and a few others for a total of $4 more than the single 323 095 adapter alone. So the list looks like this:

Speedo: 437 155
Fuel: 301 105
Temp: 310 1052
Tach: 333 158

I would guess your sender is worn.

I am doing the same upgrade and this is the response I got from Rob in ABQ; who is the man BTW.........

A good upgrade for all D90s is to go to a VDO temp gauge and sender that has actual numbers so that you can tell exactly what temperature the engine is running. The gauge is a direct fit into the instrument panel. The sender requires retapping the port on the intake manifold, but can be done without removing the manifold.
The sender you need will be a 3/8NPT thread size. The truck comes with a 3/8BSP sender and must have a 3/8NPT tap run into it to open it up for the new sender.
Regards,
Rob

Hey Todd,
Thanks for that info, my only concern is the deifeence. Between the 95 & 97. Not sure if that would change things up a bit

Yes that I dont know but I would think they are the same. Rob also said that the aftermarket fuel gauge will not work but all other gauges will work.

Per Rob:
"You will have to retain the original gas gauge as none of the aftermarket work on the same resistance parameters"

I'm not sure that I can agree with what Rob is saying. The VDO gauge mentioned does work with the stock sender. I've had one in place for years and did a bunch of testing on it.

I ran into the problem with the 300tdi and the fuel sender is that the replacement didn't fit my tank. The replacement is connected with 4 screws to the tank the one currently in there is a twist and lock into place.

There are so many posts out there on the VDO. Thanks for putting all the info into new post.

It would be great to have a spreadsheet like list that summarizes which gauges and or senders for each year range and engine. Would be nice also to add it into the FAQ's. As far as the fuel gauge goes, seems from reading other posts that it should work as a plug 'n play. I am still wondering if anyone has replaced the fuel sender along with their VDO swap on a '97 and if it solves the bouncy needle issue.

Bouncy needle on cornering is due to the tank not having baffles

I cheated on the temp gauge and bought a kit with sender included and a bunch of adaptors I ended up not needing for my 97. My parts list says it was 310-1051 but I can't confirm right now as the eGauges site is acting up.

The sender screwed directly into the inlet manifold. No drilling or tapping required. I ran a new wire to it from the gauge but if you use the very skinny/iffy stock wire you will need to put a new connector on.

Ian,
Would you confirm 310-1051 when you get a chance - I was thinking it would be the 310 1052 (as that's the the one with the additional metric adapters) - but if 1051 works, than that's great to know!

Jason,
Bouncing fuel gauge is all the time (even standing still) and really only makes me nervous when I start getting down to a quarter tank. After that, there's very little way to know how much fuel I have left. If replacing the sending unit would fix this, I'd love to know about it.

Thanks All!

pull your current sender unit out and take a look at it ... I would have thought you'd be better off getting the 'original' sender and matching it to a new gauge rather than trying to fit a new one. If your tank is a NAS tank then the sender and pump are all one unit which is around $500!

Hi Aaron,

It looks like it shouldn't matter. I ended up not needing to use any of the adaptors, just screwed the sender that came with it direct into the manifold. Both kits contain a 1/8-27NPT sender and 100-250f gauge. Only the un-needed adaptors are different.

Looks like the adaptor is 323-057 and the gauge is 310-105 but together they cost more than the 310-1051 kit anyway.

Ian

So I already had put together a list a while back and found it sitting on my computer.... I'll clean it up and put on the web next week when I have time (wheelin this weekend..).

My records do show the V8 water sensor is M16x1.5 Can someone confirm this? I do not have a V8 or parts available... Oh, I see that Ian is saying it is 1/8" NPT. I wonder if there might be a change through the years?

edit: Funny reading on the net people are saying 5/8"-UNF which could be mistaken for M16-1.5.....
