Looking good! Keep the photos on your progress coming.

You can't tell the year of manufacture from the VIN on an A3, only an A2. The best way is to get under the truck and into the engine bay and look at all of the ID tags you can find. Look at all three axle tags. Look at the tags on the hydraulics for the winch. Look at the transmission and...

If the fuel filter is full and the separator valve is open and nothing comes out when you crank, don't trying starting the engine anymore until you find the cause and correct it. Continued cranking only puts wear on the starter and those starters are expensive. If the check valve on the tank...

The 3116 CAT engine in an M35A3 can be notoriously hard to get air out of the fuel system. The fuel filter sits upside down, so you can't fill it before installation. Just changing the fuel filter can require a lot of engine cranking. I've found that after I change the fuel filter, the best...

I ran into a guy in Minnesota that told me he paid $17K for an A3 when they were first being released. The poor guy was convinced that they would escalate in value due to the small numbers. I wonder what he thinks of his investment now. I have to say that my A3 has been very dependable. My...

You should find out what the actual year of manufacture is. All were advertised as 1993, but they were built through 1998. However, you had the option of putting whatever date you wanted on the SF97 request. I found out that mine was manufactured in 1998, and my Georgia title states 1998 as...

The plastic battery boxes are far superior. They don't rust out and are relatively easy to slide in an out. Plus, you can find them cheap if you look in the right places.

That might explain a lot! :funny:

That was a good thought, but no, that wasn't the case.

I pressurized the hose to 25 PSI and used soapy water out of a spray bottle. I'll take your suggestion and repeat the test and submerge the aux fuel hose in water. This is very easy to do.

I absolutely agree with you. It has to be on the suction side. Perhaps there are multiple pinholes in the hose that are small enough that I didn't see any bubbles with the soapy water when I pressurized with air but between all of them enough air gets in to kill the suction of diesel fuel. Or...

I would recommend trying to find manuals.

My 1998 M35A3 has all of the hub to drum bolts safety wired. It was heavier gauge wire than I had on hand so I found the proper wire on Ebay.

Definitely the correct pump for both original and new. I ordered a new FACET 480517E pump from Yacht Supply Depot as they had the cheapest price I could find. Both pumps produce the specified PSI on the output side when using short input tubing to diesel supply. This hasn't been a significant...

Definitely has proper voltage at pump when running and also when I jumpered the pump directly to the batteries.

I've let it run as much as one hour.

If the dataplate isn't original, I would advise you to compare the numbers on the data plate to the numbers stamped on the frame. When I was in the Army, it was very common to swap data plates and change USA numbers. Before inspections, we would sometimes visit another unit, steal the vehicle...

You definitely want one of the plastic battery boxes.

Draw tube is clean and clear and the line to the tank is clear. I did bench test both the old and new pumps. Both work fine with short hoses although suction is not a high as I would have thought. Both behave identically. I can blow through the line to the tank with the solenoid valve open.

Yes, and I always keep the cap on unless using the aux pump.
