| Cost - Howell TBI Installation |
| |
When Jen got her Jeep, she took it out on some easy to moderate trails and
each and every time she would go up an incline or down a little slope, the Jeep would stall out. This became
tiresome and she knew she wanted a solution so she wouldn’t have to keep restarting the Jeep. Fuel injection
started looking like the solution to the problem.
As we started researching the possibility of fuel injection, we came across a lot of information about how to
bolt it on to a 2-barrell setup, but nothing when it came to the 1-barrel setup. The 1-barrel carburetor is
bolted to the 1-barrel intake, which in turn is coupled to the exhaust manifold. In short, we needed an entire
2-barrel setup before we could proceed any further. I started looking on eBay and other sites to find an intake
and exhaust manifold. Once that was settled, we were able to order up the kit, which is mostly complete and
then start to put this on.
The kit was ordered up from 4wd.com as they were the
cheapest place I could find with my parts discount. In a few days the parts arrived and we were able to start
getting it ready to assemble and install.

Total Time:
30 Hours
NOTE: This has to be broken down into pre-fitting time to make sure that the newly purchased early
80’s 2-barrel setup and aftermarket exhaust manifold would fit on the engine prior to installing that and the
TBI setup. This took about 4-5 hours to get all the stuff out and new stuff test fitted and then the rest of
the time was just installing the TBI setup as well as cleaning up the “new” intake manifold.

| Cost - Offset |
| |
| To offset the cost of the buildup, there are a lot of parts that could be sold.
We have the old mechanical fuel pump, the carburetor, the intake and exhaust manifold for the 1-barrel setup.
I don’t know how much this would run, but it could be done for some good money I suppose since this is such a
vintage setup and you can’t really get these parts anymore.

| Conclusions |
| |
The total time should be around 20-30 hours all said and done for installation. That
being said, some time was spent fitting to get everything to line up right. If you have a 2-barrell setup
already on the Jeep, obviously this will go faster and cost less money.
A second pair of hands is almost essential on this installation. The old manifold setup weighed a ton when we
pulled it out; the aluminum was nice and light going back in. Also, there was no need to put the 2 in at the
same time, you could do it separately, which was a lot easier to do and didn’t hurt the shoulders as much.
