(I read 6 ohms > [Rest of message deleted] I had the exact same problem on my '78 camper. I believe you have a fuel sender that opened in the middle. A new sender's resistance at full scale is much lower than 240K ohms, mine was in the neighborhood of 80 to 100 ohms, I believe. Before I fixed the problem by replacing the sender, I fooled around with the voltage stabilizer adjustment, to no effect. If you have the "toilet bowl float" type fuel sender, like I got, you CAN take out the old and put in the new without yanking your engine or undoing the fuel tank straps or chopping holes in your bus. If you unbolt the crossmember supporting the motor mounts and lower the engine about an inch or 2, you should have enough room to remove the sheet metal cover for the fuel tank. Clean the area above the fuel tank with a wet rag. Take an old screwdriver and bend the blade into a mini "backhoe" and use this to turn the twist-lock cap for the fuel sender. I managed to to get the sender out by shoving it through the gap on the right (the passenger side), though at times, I didn't think it was possible. Good luck. Even though I don't remember doing it myself, you should disconnect the battery and have a fire extinguisher handy. BTW, I would not have known about this technique had not another netter, Monique Deveux (spelling?) wrote a reply to my posting earlier this year; thanks Monique! -- Tom Quan Tom_Quan@smtp.svl.trw.com ------------------------------------------------------------------------------ Tobin T.
