Ford 5000 fuel tank with Simms injector pump

I have been trying to rebuild a 1868 Ford 5000 with a Simms injector pump. I
have noticed that all of the fuel tanks that are available for purchase
online say they are NOT for use with the Simms injector pump. Can anyone
tell me the difference in the tanks and why none of the tanks can be used
with the Simms pump?
 
Looked at the picture illustrations. If I remember correctly, on the left upper front face should be return line fitting, none of them have that. Should be easy. Drill a hole in the new tank, solder in the correct brass fitting. 3/16 inverted flare if I remember correctly. If you have the old tank, check it out.
 
That is what I was wondering as well. I found a place that would split the tank an fix the original tank, but it is a very expensive option. There is a small return line on the right front of the tank on the bottom of the tank. I didn't know how hard it would be to put that fitting into a new tank. Or even if I could find that fitting. The book that I have shows the return line going back to the filler neck. I wasn't sure how critical it was verses just going back to the filler neck.

A regular diesel tank for a 5000 with the fitting in the filler neck would be just fine. That fitting at the bottom of yours most likely has a standpinpe on the inside of the tank that goes up to the top to empty above the fuel level in the tank anyway. If there isn't a standpipe then there's always pressure in that return line that the pump has to push against and I doubt that it's designed for that.
 
Interesting, Im going to have to check our fords now. I know our 5200 has a sims and it is a non-return type pump, only fuel return there is is from the injectors.
 
The line on the side is a stand up line. It
extends from the bottom of the tank all the
way up the side. It's not quite as tall at
the tank, but it's close.

I don't know where your tank came from but it is probably not original to the tractor. I just checked the parts drawings and the drawings for the Simms and CAV diesel fuel systems both show the return line going to a fitting on the filler neck, but the fitting on the tank for the CAV system faces the front of the tractor and the fitting on the Simms tank faces toward the right side. So either tank can be used, it's just a matter of fabricating a return line to approach the fitting on the filler neck from the appropriate direction.
 
I have looked at the drawings as well and I
am also stumped because i dont see it the
line on the tank either. I assume that the
whole tractor is original, but I cant be
sure. I looked at the manufacturing code
and serial number and again I am stumped on
what this tractor actually is. Here is a
picture of the stamp on the right side of
the tractor.

8F10 would be the unit Number for May 10 1968

B092765 is a serial number for a tractor assembled at the Basildon UK plant that was built to be exported outside of the UK. That serial numbr is correct for th eUnit Number above. The Basildon export serial numbers were at around B088 on 4/1/68 when they switched to the newer smooth sided hoods and inset grills.

Their should be a third number, which is the model number, and it is most likely up above those other 2 numbers in the picture, stamped into the rougher part of the casting. It may be difficult to make out.
 
Thanks Sean, I will look for that other
number when I get a chance. In my research
I thought it was a 233 diesel. But could
not figure out why my calipers showed a
bore of 2.4" instead of 2.2" then found the
serial number on the block casting that
said it was midyear 1968 they changed to
the 256 diesel. Also here is the best
picture I can find of the line on the fuel
tank.

A lot of the earlier 4.2" blocks were bored oversize to 4.4" in the field. I'm not saying yours was, rather I'm pointing out that there are many pre-'68 blocks out there that are actually 4.4". Makes for thin cylinder walls though.

His Unit Number puts it after the 4/1/68 changeover to the larger displacement engine.
