Is this the AMX at Daytona with rear 1/4 panel gas tank access?

I also made a fill spout for my cars. I cut a piece of 1 inch Home Depot schedule 80 pipe stock. They sell a 2 foot stick that worked just right. Cut it into 2 pieces about 9 inches and 11 inches. 45 degree ell (elbow) in between the 2 pieces. Finished it off with a long-neck filler spout cut to fit into the upper end. Gravity flows just fine to keep up with gas going in. Bungee'd it to the trunk latch. I made it after I pissed off a gas station attendant for spilling gas.

Maybe a metal extension that would be similar to a gas cap fitting with clamping ears so the two will attach. Could have a slight bent in the extension that would tilt up. |

I just use the gas cap on the White70 and wedge it in between the license plate frame and the lower valance panel. The homemade tool is definitely awesome though.

I installed a billet gas filler neck and gas cap assembly on my 68 Camaro. It caused gas to back up because of the bend in the neck. So I would push a 10" long fuel hose (7/8" dia?) onto the nozzle and push it past the bend and fill up. Worked great. This might make filling up an AMX easier. So, in the trunk store a piece of hose, license plate stay-open tool, and a small rubber mat to place your knee on. Cheers

Yeah, I remember those. It's like a swollen gas strut boot on the pump nozzle.

Very clever. My GN has the spout higher and the gas cap actually holds the same type of license plate door open. One of the problems is; the Ca. gas nozzles are massive. |

BTY putting gas in this car with the Ca nozzles is a PITA. You almost have to lay down to access the gas spout. Jeff [/QUOTE]last month, member AMXTSY posted photos of a license plate stay-open tool he made. This make refueling easier. Search "license plate tool." See photo. |

96.5:1 compression ratio?! What octane does THAT require? Just kidding....
As for the fuel needs, I have a 1970 390 with stock 291C heads and with the .030 overbore I get around 10.4:1 compression ratio. I am able to use 91 octane gas with no ethanol and it seems to work ok. I have the advance set fairly conservatively and the total advance is around 36 degrees total. Chris
