Very cool. Just wondering why you didn't go w/ one of the new plug-n-play throttle body fuel injection setups? It seems like a much easier route to the same end.

BTW, thanks for all the tips and suggestions. Good group of folks around here.

I haven't the foggiest idea. It was bought new and the only thing I did was change the jets. The car is currently buried in boxes until it cools down and I can fix a few other issues. I've received a couple of other tips and will apply when I yank her back out of the garage in October.

SMI Holley 4BBL Vacuum Secondary 750CFM

plumkrazee70, Thanks for asking. I vented the cap when I got to Iowa, but still had some stumbling with a full tank. After a few miles of driving, the stumbling subsided. Half way through the trip I also downsized the fuel filter and covered it in a head shield. I think the larger diameter...

I think the very best option is to run a carb and sell me the efi for $1k US. :)

All very useful information. Thanks.

I'm packing another fuel pump just in case. :)

Update: I drove the car yesterday afternoon for about an hour, with the gas cap off. Equal mixed driving this time around (50% city/50% highway). The temperature was between 85 and 88 degrees w/ 70% humidity. The car didn't stall once. It did sputter one time, but I'm pretty sure it was due to...

Got some days in the 80s this week. Just waiting for a day when it's not raining for hours on end.

I couldn't wait any longer. Kids in bed and wife busy on the phone. Time to test the car without the gas cap. I know it's not sunny and 90 degrees. It's 78 degrees and 81% humidity. I drove the car 30+ miles without an issue. Mixed driving, but mostly highway, and no stalls. Popped the hood...

I want to publicly thank all you guys for your advice. You guys are great.

I tried that last summer with mixed results. I'll try again this week. If that doesn't work, I'm going to make those fuel lines look like a mummy.

I really appreciate the help. The current line is brand new prebent 3/8". The old fuel lines are long gone. I'm going to take your advice and shield the line between the pump and carb. I hope DEI has a frequent shopper program. :D

I wonder if I can get by with adding more heat shielding around the fuel line in that area? I seriously don't have time to reroute the line (the right way).

Overview shot

The carb is a 750 cfm Holley Vacuum Secondary SMI carb. I had it built for this car. I've never seen any trash in the fuel filter. I did notice the hose between the chrome carb fuel inlet line and the fuel filter was pretty hot. Also noted that fuel filter fills up with fuel once the car cools.

This same problem has been persistent. However, the car isn't driven much. I had the same issue last Spring/Summer and not so much this past Winter. As many of you suggested, vapor lock has been my guess too. I just thought the cool tube over the fuel line would fix the problem. It hasn't...

I'll post a picture of the line between the carb and fuel pump after I put the kids to bed.

Sorry, dinner and kids. I have DEI cool tube around the 3/8 fuel line between the fuel pump and the firewall. I don't have any cool tube between the fuel pump and the carb. The fuel lines follow the factory path and are pretty close to the header primary tubes in spots. I have no room for a...

Could sure use some help. Leaving for Power Tour in 2 weeks. I'm running a mechanical fuel pump on my 360ci/380hp Magnum crate. Just did a few miles in the car and suddenly the car dies while cruising at 40-45 mph. I have a clear fuel filter between the pump and the carb and there is barely...

Love that 74 Swinger. Looks like we have twins of sorts. I like your ram air setup. I also like your fuel injection setup. I've been debating fuel injection for a while and keep waiting to see how much easier and cheaper it can get. I'm leaning towards the Edelbrock setup with the external...

I'm running a Mercury Cougar hood scoop on my 73 Swinger and I'm looking to seal the air cleaner base to the hood to make it functional. I'm using a 11" K&N X-Stream element and lid. I'm batting around the idea of using a non-stick 12" cake pan to make a new air cleaner base. My question for...

I would love to hear more replies

Saw this after a bit of web surfing. Looks nice and professional. You can order different heights from 3" to 5".

More pics of ram air setups, please! I just hacked a hole in the hood of my 73 Swinger to clear the air cleaner, have a Cougar Eliminator scoop on the way and really want to seal things up and make it look good. Thanks!
