Well after the engine swap all went well until emissions testing time, and I couldnt get the thing dialed in to pass the sniffer. I tried to rebuild my carb but the shop that tuned it for me the previous year stripped one of the jets and over tightened it. I tried my darndest to get it out but it was messed up and jammed in there too tight, i trashed my carb in the process. It was an Edelbrock 1403 (500 CFM performer).
I picked up a new unit on CL still in the box for $200 (musta fallen off the back of a truck, I didnt ask). Put it on the truck, and it just missed the sniffer by a hair. I dropped it off at my new mechanic and paid them for an hour of labor to get it to slide by the sniffer, which it did with zero issue. They probably just bumped up the idle.
Well, truck was running well, but I still had a few known issues. I had what i assumed to be fuel percolation problems, as in the extreme heat the truck would surge a bit on the highway, but it never vapor locked. I installed a 1" phenolic spacer to try and isolate the carb from the heat. I also have had issues with my fuel system venting. I never mentioned it but one of the PO's used the truck for towing, and had installed an auxiliary fuel tank, with a valve switch and a small electric pump to prime the mechanical pump when the tanks were switched over. Sweet bonus right? Thats expeditiony!
Well turns out the most recent previous owner had vapor locking issues but before moving the dang fuel line away from the exhaust manifolds, he went and chopped out the OEM tank, and removed all the lines for the vapor canister, removed the lines to the e-pump, and welded shut the filler tube so it ended after the aux tank. son of a b! So this whole time i'm running off of an AUX tank that was like 19 gallons (great range at 10-12mpg haha). But.....it worked. It wouldnt vent correctly, and i had already done a bunch of work because the dang filler neck was a bunch of pipe and 90* fittings so it was a major PITA to fill at the pump, and not to mention there was no breather tube attached so the damn tank was venting into the interior of my truck. you about got choked out just sitting in it. I fixed all that crap in the first few weeks of owning it though. All that crap is covered in my build thread.
So, as I said, things were running well enough that I decided it was time to see what the old girl could do.
Camping time! :REOutCampFire03:
I loaded her up, fueled up on a 98* day in September of last year, and hit the highway headed north. The Destination was Ely, NV, about 250 miles north of vegas, at about 7,600' elevation. I didnt really know what I was in for. Driving down the highway with a full tank of gas the truck started to stink. I discovered I was pouring fuel out the filler cap. The tank would heat up because the exhaust was dumped right before it, and the road was probably 115*. It was pouring out as I drove down the road. I pulled over, removed my gas cap to let the pressure out, put it back on, and carried on. Truck was surging like crazy so I pulled over again. I removed the cap and it literally shot gas out like a hose. Crap.
Well, easy remedy here. drove without the gas cap for the next 100 miles until we gained elevation and got to cooler climes. After relieving the pressure it drove fine, except for the random corners where i would slosh like a gallon of gas out the side.
Comforting sight with a 19 gallon tank, 10mpg, and a broken fuel gauge haha. I had some jerry cans though.
So, in my true (dumb) fashion, even though I was having LARGE problems withing the first 20 miles, I pressed on, and we made it up to Ely, through the mountains, without further issue. However, had i known the rest of the things that would happen, I'd have stayed home.
I coasted into town on what I assume was my last gallon of gas, and filled up with 85 octane mountain gas. (bad bad bad idea...but little did i know) then headed off to our campground at Ward Charcoal Ovens (15 miles outside of town). it was well into the night at this point, so we set up camp and crashed.

Well, our friends from Vegas spent the first night in Rachel checking out Area 51, so my girl and I headed off into the wilderness to check out some local ghost towns we knew about.
Where you see the jeep in those two pictures was where it died, by the way :Mechanic:
Truck would not start back up. Mind you i've swapped an engine at this point, but have almost no experience troubleshooting, especially with carbs. I've never had a car that had ever broken down before.
I rolled it back down the hill to level ground and was getting kinda panicky. My girl didnt care, she would reather break down in the middle of nowhere than on a road.
For some reason my carb was bone dry. Not a drop of gas getting to it. I cranked and cranked but could not get it primed. Eventually I got the smart idea of feeding gas into the carb by hand, and it fired. I then used a hose and a bottle to fill the bowls, removed my standard fuel filter and put in a glass one with a servicable filter element (bad bad bad idea, btw....all this foreshadowing!) and had my girl fire the truck up. Started right up and as it was running i connected the fuel line and had her bring up the RPM's and the mechanical pump got enough suction going finally to prime the lines, and it ran fine all the way back to the campsite....
Finished our evening and the last day we were headed out of town, but decided to stop off and go for a trail ride beforehand, now that there were two jeeps. I pulled up a hill into a parking lot, and yup...it shut off all on its own. had to roll it flat to get fuel into it again. I decided 'screw it, i've got 250 miles between me and home, i'm hitting the road'
Rolled into town, it died at the pump again, filled her up with that lovely 85 octane again, and couldnt barely get it started. It was acting flooded. Had to hold the throttle open, it would fire, dump a crap load of black smoke out the pipe, then run mostly okay. I figured now or never, and started bombing up the road with our friends behind us. I almost made it up to the 7600' peak of the mountain headed out of town, pouring smoke everywhere, truck sounded like crap, stunk to the high heavens, and as we were starting to descende the mountain headed south, it killed out on the highway doing 65mph. . Stopping a 5000 lb truck on 4 drums with now power brakes or steering at this point, headed downhill, was not a fun experience. I pulled over, popped the hood, and let her sit. I went off and took a bathroom break in the woods, hung out for 20 or 30 minutes, and fired it up like it was flooded. Got started, and boy if I didn't keep that pedal to the floor for the next 150 miles to Alamo, NV.
It killed out at the gas station there as I was coasting in. Filled up, got it fired, and bombed the last 100 miles back into vegas. Ran 100% fine as soon as we got home. I let it sit and a few days late couldnt get it more than 100 yards down the road without it flooding and bucking and surging. I ended up breaking down the carb and found out that my dang servicable fuel filter had worked loose and was just letting all kinds of crap through into the carb. Great. Ya big dummy!
Brand new carb was full of rust and the needles were all grimed up.
Cleaned it out, but a real filter back on it, put a filter back by the tank too, and hoped that would do it.
nope. still acting up. It turns out it REALLY didnt like that crap tastic 85 octane. I drained the tank, put in a bunch of 91, and never had that issue again. Live and learn I guess. But on the bright side, i can break down and rebuild an edelbrock in about 30 minutes now, and i know my way around the adjustments, and get how they work!
So, as you can guess, all of these issues lead to some further modifications a little bit down the road.
All in all, it was a successful first trip. The jeep and I made it back just fine, despite it's best efforts to ensure otherwise, literally from the first leg of the trip.
More to come.
