Truck Breakdown part II

[Nickathome]

I pulled the fuel pickup assembly out of my truck last night, and I am almost embarrassed to mention that the reason my truck died on the road was because I simply ran out of gas. The tank had about 3/8ths of an inch of fuel in it at most. The tank is surprisingly clean inside though with only a small amound of particles floating around. Much less than I had expected. I did notice my float assembly was bottomed out about two inches above the bottom of the tank. I would have thought it would be sitting lower than this. I was surprised to see that the pickup line in my truck is just a simple 3/8ths inch tube bent into the shape of an upside down question mark with not filtration of any kind on its end. Just an open ended tube. This looks homemade to me. I do think this tank is not original so that probably explains things. Where can I get a replacement fuel pickup assembly that has an internal filter?

Nick,
The question mark shaped line is what I have and I believe this is the factory pick up line. I am not sure how far the float should be from the bottom but if 2" is right I would imagine it is that way to leave some reserve fuel after you show m/t. Or did you show fuel on the gauge?
Perhaps you could plumb in a small spin-on fuel filter block assembly right in front of the fuel tank, mounting it off the frame? That would keep debris from traveling the whole length of the fuel line

Nick - mine was actually a piece of rubber gasline with a fine nylon mesh screen over the end. I now wonder if the rubber is going to degrade over time?? Anyone?



I added an in-line filter back by the fuel tank seen here:

My electric fuel pump is mounted on a cross member directly in front of the tank. The only way to mount an in line filter there would be to do so past the pump, which would protect the fuel lines, but would do nothing to stop the pump from getting full of crud. I would like to be able to mount a filter in the tank on the end of the pickup tube if I could. Is there such an animal that could remain immersed but be able to attach directly to the end of the 3/8'ths metal tube that I have?

That could work. If you have ever taken an intank pump assembly out they have rubber hoses in them as well. But it may not sit well on the bottom of your tank as you might want. You do have an option use a compression fitting at the same place that your hose it attached to the pick up. That could get you going, as faras steel line in your tank. And then you could reattach the strainer to the new steel line with a small pice of rubber line as your transition pice. I will be honest and say that there is no strainer in my tank. It is stupid of me but for now the screen in my facet pump acts as the strainer. But do you have a part # for that strainer cause that seems to be just right for the application. And I will with out a doubt take your idea and use it on mine.

The early M37's up into 1952 did not have the in tank fuel filter. The filter was mounted in front of the voltage regulator. The later in tank filter is much better at filtering out junk.

I have found a few complete units with the cover, fuel tank vent, pick up tube and the filter. They will not arrive here until end of November. If anyone is interested, let me know.

I also will have NOS intake/exhaust manifold assemblies; Fording kit air filter shrouds: US made NOS with good diaphragms fuel pump overhaul kits: Standard and.060 oversize pistons: Standard chrome rings: New radiators for the flat fender Power Wagons and M601 Military version of the Power Wagon; plus a lot of other items.

My M37 parts list now has over 1000 items on it and is available as a Microsoft Excel file. If you want a list and can open Excel, just let me know. Sid

Nick,

I have the same ? shaped early pick up tube. For a strainer, goto Advanced Auto parts and look through their fuel tank strainer box. It contains about 20 different sprainer types. Pick a long strainer that slips on to the tube end - and fab/zip-tie a method to keep it in place.

I ran the universal military elect f/p used in generators and M43 rear heaters (among other things) on my truck in the same location as you. It incorporates a resusable pre-filter. (Saturn Surlus is where I got mine) and is 4-6psi, so no regulator is needed.

Drew;

Thanks.

NICK, I have my tank out right now and and the fuel pick up in my tank is the same as you described. I had my tank "dipped" at a radiator shop, then finished cleaning out the inside, and painted it. Got a new sending unit from Adirondack Dodge. I also want to install an elect pump near the tank with a clear filter prior to the pump. I am considering using a rubber gas line all the way. My M37 is a driver and does not have to be "correct". Not sure if I need the return line to the tank or not. Any ideas?
