  1. Not bushings. Eccentric bolts. I'll look the tech desk request up and link it tomorrow.
  2. Yep. You should be able to. If you need some extra material, I submitted a tech desk question and I am allowed to make my own eccentric setup with repurposed parts. No reason you can't slot a hole and redrill a washer.
  3. If it's a safety issue, make the rule directly address the safety issue. Fuel capacity is not a safety issue. I agree that the intent has to do with safety.... but, its like giving us 5 minutes for a pit stop so we don't spill fuel.... why not just make a rule against spilling fuel?
  4. I'm not so sure the e30 are going to be impacted by this that much. They already have pretty large tanks and can go up to 18.9 gallons legally. T hats a lot of fuel.
  5. Well, if you do it at an extreme temp, then you are gaming the system and you should expect to get smacked down. Just simply fill your car to the tippy top. Then pump it out till it won't come out any more. Then fill again to the tippy top and see how much fuel that took. Thats your fuel system capacity. I don't see how people can really game this. Changing the temp of the fuel would be pretty obvious. Getting back to the REAL issue at hand..... What is the reasoning behind this change?
  6. For sure! Nobody is arguing that. Fuel expands! However, if you filled that tank and pumped it right out (no matter in spring or winter or summer), the amount going in and out would still be 275 gallons.
  7. I do. But your wrong. The cell doesn't change size. Therefore, it can not hold any more fuel than its physical size. If you do a pump out test in Florida or do one in Wisconsin, the results will be identical. That being said, your fuel volume will change if the fuel changes temp. In the case of a pump out, the fuel is NOT going to change temp enough to make a difference.
  8. Exactly! 18 gallons is 4158 cubic inches. It will always be 4158 cubic inches.
  9. I tell ya what.... fill your tank with fuel in the middle of summer. Figure out how much you can pump in. Then fill your car in the middle of winter... I can guarantee you that it will be the same exact volume. If it is not, your car has created a wormhole.
  10. Doesn't matter... Volume of the system does not change. It can't hold MORE fuel than what the internal dimensions allow.
  11. Yep, fuel expands or contracts with temp differences. This is true. How does that effect a fill and pumpout?
  12. Nobody is saying the fuel itself doesn't change volume with temperature or pressure differences. We are saying that the volume of the fuel system doesn't change. Unless you apply a temperature or pressure variation DURING the test, the volume of fuel does NOT change. 1 gallon of milk has the same size container in Wisconsin or florida.
  13. No, it won't. Really. It won't. What dimension of the cell is changing? Volume is just linear measurements multiplied by each other. L x W x H. Which one of those is changing due to temperature?
  14. I cant.... I just cant.... This assumes that the weight is not changing... It is also referring to a simple object. It would also require some way to change the density (temperature or pressure). We wouldn't be applying any temp or pressure to the system while performing this test... Are you guys being serious with this?
  15. I looked into this and found that the vessel itself is fine. However, the cap and the seal on the cap on most of these containers (including oil bottles) MAY not last.
  16. Just curious... how do you get it IN the cell?
  17. Uh, yes it can.... In fact, that's exactly what changing density means.... different weight in same volume.
  18. Are you planning on heating or cooling the fuel when doing this at impound? If not, IT DOESN'T MATTER.
  19. So with your filler, you are at more than stock plus 2 gallons? (The above was a bit unclear to me) I'm trying to get a feel for how encompassing this change actually is.
  20. No, it won't. If you fill it with 15 gallons of 35 degree fuel and pump out 35 degree fuel, you will get out 15 gallons. If you take that same exact system and fill it up with 100 degree fuel and pump out 100 degree fuel, you will still have the same exact 15 gallons. However, the density of the 35 degree fuel will be higher and habe more "energy". Volume will be exactly the same.
  21. Setting aside the change to the competitiveness of the affected cars.... Can't a displacement block just be put in the cell? Are there really stock tank cars getting 2 extra gallons out? I'm asking, because I REALLY don't know. My question for this entire situation is why? If it's safety, make a rule that directly impacts the safety. For example, only allow so much fuel in the filler neck, or make a maximum length and diameter of the filler neck.
  22. Agreed. I'm not talking about that part. I'm talking about people riled up about how it will be checked. I am not going to contribute to the new ruling regarding capacity. My car is borderline able to make it 2 hours with a stock tank, so I am not directly impacted by this change.
  23. I'm kinda confused why this is suddenly an issue... Isn't this how cars were checked for fuel before? Didn't we have a wee bit of an incident earlier this year that set the precedent?
  24. This is all making my head hurt.... The process for pumping out and filling the cell is all going to be at the same temp. No chilling or heating of fuel. And no, they didn't put 23 gallons of fuel in. They put 22 gallons of fuel in (that can then expand due to quick temp changes). It is not possible to put in more fuel than the system can hold. You can change the density of the fuel. However, density is not part of the volume equation. It's just volume. The only way that density or weight COULD play a part in this is if the fuel changes temp. I believe that the check will happen as quickly as possible and isn't going to let the fuel cell sit in the sun for a few hours, and the fuel being put in isn't going to be chilled. In other words, the volume of fuel doesn't change if checked at the same temp. Is somebody planning on heating or cooling the fuel and or components during the process?
  25. Just curious, but can't you just throw a displacement ball in there and be fine?
