Hi all

Well I thought I would get your idea on this one. The coronet is running real well, but it seems to be running out of fuel at the top end of third gear. I noticed last night in both races with Tusk, that the car pulled well up until 5600 in both 1st and second gear, but just at about 5000 in third she started to nose over a bit. hen this happened to me at the track before, I thought it might be fuel boiling due to the mid 90's temps and humidity up the ass. Yet last night was cool and this didn't seem to be an issue.

For the record I run about the biggest Carter mechanical fuel pump they make and it p-umps a very generous 6 to 8.5 psi of fuel on command. The fuel lines are 3/8 all the way down to the tank which has a 1/2 inch pick up. i eventually plan on replacing the old fuel lines, and just to make sure I picked up a new sending unit last year, cause the one that was in it was put in during the Nixon administration.

I know what you all are going to say, which is shrug and go electric, but I'd really like to keep the carter, just cause I like to leave this as stock looking as possible.

What do guys think about putting an auxillary pump down by the back to keep flow constant from the tank? Again best of both worlds it keeps the fuel constant and also remains fairly stock looking.

I thought about using this?

Cute, small and to the point!

Opinions!

Have you pulled the plugs to take a look at them? Its a possibility that you are dumping a bunch of fuel at in the upper RPMs, causing it to nose over. What is your rear end gearing again?

You, know I'm not sure what pressure is at 5000+ and that would be a good place to start. Brian, thank you for the offer. I'm taking it over to get dumped here sometime this week and I got the bungs on it so good place to start.

My 73 does the same thing. I got a new, bigger mechanical fuel pump. Just haven't put it in yet.
