Figured at least 20mpg because hardly over 4000 rpm around town. I know carb needs a rebuild, just have to figure out which kit to get. Older Nissans didn't emboss numbers on carb bodies, just attached a silly little aluminum tab to a carb screw and I have yet to see one that has lasted. Then, with carb and cleaner off, will replace ALL those little tubes.

Decal gone but that looks more like what I should have. Runs ok (except for needing carb rebuilt) but only getting about 15 mpg. Have had a few 720's and should be getting twice that. I think the missing components might have something to do with that. Thanks Mike, your the go to source.

Somebody posted a schematic for all those friffin' 1/4" size rubber lines running all over the engine bay, shows one line going to passenger side (inner fender I am assuming) but I have 3 thingies there. 1984 720 4x4 xcab.

So, sensor powered?

Have three or four dashboards in my shed,might have a tach. Before you go crazy, though, check the drive cable. Vancouver Island, BC, Canada

If you really must have a diesel, consider a 3cylinder Yanmar. Don't know if adaptors are available to the tranny, though. Big deal in Europe right now, people putting Cummins into old American built cars.

Now I AM irritated. Sold my 1993 50 xcab 4x4 with same driveline. The '93 had the one ton running gear.You are getting about what the new trucks are getting but no matter how often I checked, was getting around 27 mpg town and highway with a camper on. Maybe different gears in the one ton? That was better milage than my '84 720 Nissan. In all fairness, I do know the 720 needs a carb rebuild.

If you want to go that route might as well buy an old Dodge 4x4 with the 12 valve Cummings and drop the 720 body on top. Be much cheaper but will still have to extend the 720 body about two feet on the front to make room for motor and radiator. Height won't matter, just lift body until there is room.

Boils down to two things, not enough room and the suspension/running gear can't handle the power/torque.

No way to tell from that picture. I have an 84 720 4x4 with the 22 engine but I know that because I put it in.

Let's see.......Cummins (turbo of course) is twice as tall as the stock motor, twice as long as the stock motor, about 8 times heavier than the stock motor, and we won't even discuss the sideways torque. Just off the top of my head, I would say....no.

Brake reservoir bolts to booster, no clamps. O rings in cylinder must have failed. Remove booster and cylinder, drain booster, rering cylinder (if you can find O rings for it!)So much cheap crap available on line.

I have the sun shield that came with the 84 720 still in the original bag.

Nissan wanted $180 for a fuel pump relay and 6-8 weeks delivery time. I bought two (one as a spare) online for about $70. Why would you want to screw with a broken one?

I started that thread and went through all you read. Problem turned out to be a small leak in lower right windshield gasket. Intermittent at first because relay was damp. finally failed when it got soaked. Just enough of a leak nothing showed anywhere else. Didn't discover that until I finally pulled the relay instead of testing circuits. I hate electrical!!
