The part on the pass seat is the correct master cylinder. The carburetor is incorrect. The dangling hoses are for the fuel/vacuum pump. Never seen the main data plate mounted to the battery box cover before.

Dang. I wonder if at this point I shouldn't just go ahead and re-engine the vehicle.

I haven't priced Tornado 230 parts, but I'll bet they aren't cheap.

I wouldn't. Looks like since the fuel pump is missing, it failed and the deer hunters never got around to finding a replacement. That's likely all that is wrong with the engine. The Tornado is a good engine for putting around at 50 mph. I've driven mine all over Texas and my buddy took his from TX on vacation to Durango CO and back. Runs like a sewing machine.

Meaning smooth; as in "good", right?

Looks like they moved the data plate to the battery box so the could mount a CB and a master kill switch to the dash. The kill switch is not stock.

Wonder what the MC on the firewall is from. I suppose they wanted one with a bigger reservoir or didn't bother looking for an original one if the factory unit went bad. I missed the replacement when I looked at the photos the first time. I would check the fluid and try bleeding the system to see if things are actually working. Depending on how long it's been sitting (I don't really trust the previous owner remembers the last time it ran accurately) the wheel cylinders might be locked up as well.

There is a dual circuit master cylinder conversion that is available for this truck, I am not familiar with it. From what I have seen on brush trucks and hunting trucks, something will break and someone runs into town and brings back the closest appearing part they can find.

It also looks like it has a civilian dist., plug wires and spark plugs and I would check to see if they converted it to 12v. A lot of the hard to find usually missing parts look like they are still on yours which is a great thing, especially the tailgate. What's missing looks to be common M-series items which are plentiful to find. I wouldn't be quick to count out the 230 either, they are great running motors once you get them tuned up, just remember that they are not hot rod motors and have problems if they are over-revved. That's why the later ones had a governor installed on them , to keep the RPM's down.

Trust me, I am not a hot-rodder. I believe in making vehicles last as long as they can.

Dang, I'm having a hard time finding a fuel pump. Only ones I've found in stock are at some milsurp places, and they want 225. And the original for core.

I know alot of people are going to cringe, but I think I have to go with an electric fuel pump. Given that, any suggestions about a particular electric pump?

Yeah, I think there's an aftermarket MC on the firewall behind the carb. With a wire latch on the cover.

Individual wheel cylinders I'll take off and see if they can't be rehoned and rebuilt with new springs and rubber.

Try the mechanical mentioned earlier. Just don't do a lot of drving in rainstorms.

Thanks, but I haven't been able to find that either.

I tried autozone, oreilleys, advance, carquest, napa, and rock auto.

Search terms and parts number searches for "6510" "AC6510" "AC 6510" "6510 fuel pump"

Looking at some threads online at places like IFSJA, it looks like some people were able to find some by a manufacturer called airtex at carquest as recently as 2009.

Can you see if the seller still has the OE fuel pump? If not I have some cores, and I believe that kits are available.

I was able to buy an Airtex one about 18 months ago for my M725 I just finished from Autozone for around $35. The listed fuel pump for the civilian 230 does not work with the military dist. due to the extra size of the military dist. and I can not think of which application the 6510 fit. I'll look to see if there are any cross references for a different part number for the 6510.

I can't tell in the picture, does the spot for the fuel pump have a plate covering the opening? Or is it just shadows.
