Sorry Hank, I almost never come into this forum so I just saw your question. I looked them over and they are different brands or appear to be. Nothing on either one as to the maker, just L-2 on one and Made in the USA on the other. One has 3 truss bolts and the other has 4. Tank lids say nothing either. Many were made by the oil companies themselves sort of like Gulf building it's own pumps. I haven't had the need to buy any parts for them as both work.
