LINCOLN suction gun

We have had a Lincold suction gun in the shop for more than 20 years. Our original one recently was replaced with a "new" Lincoln.
The old one could have been rebuilt, but we assumed with buying another by the same manufacturer we'd have no problem with its functioning.
Almost immediately the gun was malfunctioning.... seems liquid inside would slip past gaskets inside, or the arm would not move at all.
Mr. Fix-it assumed it was because we were now suctioning ethanol-laced fuel. Which seems to wreak havoc on any rubber parts it touches. So we decided after having this gun only a few months we were going to have to rebuild the seals inside already.  What did we find? On the old Lincoln each end was threaded in case you needed to take it apart for any reason. Well, unbeknown to us upon purchase  the new gun's ends are crunched on, and cannot be removed for any reason unless you get a cutting torch you cannot get them off.
Thoughts:

1.) Our old LINCOLN was threaded on the ends for easy access.
2.) Our new LINCOLN was not threaded on the ends for "no access"
3.) Neither rubber seal on the suction guns was ethanol- resistant.
4.) there is ethanol in all the fuel we purchase in the Northeast except for Sunoco Racing Fuel (which we can only get by traveling about 20 miles in each direction at at a cost last I checked of $8.25 per gallon)

What can we do?

1.) We can ask LINCOLN to go back to their old design with the threaded ends so we can take apart the gun to rebuild everytime the ethanol damages the seals.

2.) We can ask Washington D.C. to stop allowing the ethanol to be added to fuel and let the corn go back to being treated as food (so maybe we could afford to buy food that had corn as an ingredient)  because all the petroleum companies would no longer be vying for it.
3.) We can purchase racing only fuel to put into all the equipment we run, therefore when it needs to be sucked out from the tank for any reason we wont damage the innards of the suction gun, well if we won Megabucks we could afford that!.



What do you think the chances of any of these 3 things happening? .......Yeah, I agree.
