> I was also extremely puzzled by how fuel actually enters the unit Hi Martin, I played with it some more last night and saw better how fuel enters. I held the bottom plate in the tube and held it up to a light. Looking inside with my finger blocking the big hole in the bottom, I could see a lot of light entering around the edges. It certainly isn't a calibrated orifice, but all it needs to do is let fuel through slowly. > your > comment about the screws not actually doing anything might be a clue. I am satisfied that the two holes are there only to aid in assembly. They probably use a pair of right angle snap ring pliers to grab the bottom by the holes to tighten it down. Then the screws are there only to plug the holes. I saw a trace of green thread locker on the big cap-screw. > Then > again maybe the screw are plugging holes that were deemed unnecessary, in > the same way as the TankZilla has rivets in it (?). Not all TankZillas have rivets. I discussed it with Rob Grady at length. They put the rivets in there to slow down the movement of fuel because people were complaining about wildly fluctuating readings. Apparently the Saab's electronics have a much slower response time than the DeLorean's. But then they stopped putting in rivets because they 1) didn't look good, 2) was time-consuming to install and 3) caused some people problems with installing them. I would think that they could see to turn the unit so that the rivets passed through the keyway, but then not everyone sees the obvious. I plugged up my holes with JB-Weld, and this tamed the fluctuating gauge. > Add a tiny > amount of water to the sender already full of petrol fumes and the copper > corrodes at an alarming rate. I've played with the insides of 3 OEM senders and found that they all failed due to corrosion. Even the TankZilla is not immune to this. I bought an early TankZilla on eBay (to have as a spare and a curiosity) and found that the whole top inside was an encrusted layer of rust. Most of these corrosion problems are probably due to stagnant fuel and wouldn't be a problem if the cars weren't improperly stored for long periods. But exposed to the same conditions, the new DMCH sender should last many times longer. Walt To unsubscribe from this group, send an email to: DMCForum-unsubscribe@xxxxxxxxxxxxxxx Your use of Yahoo!
