Just a little elbow and the hose goes up the frame a tad. If you plan on a lot of water fording you'll want to run them up to your firewall.

Got plenty of time until the water is liquid around here
Also, do they need the valve like the axle has?

Or, you could put them into a home-made manifold of Tees and use a single CCV-like breather filter. I think some guys have even used fuel filters before

alright guys,
So, we've got more adventures with the wife jeep. It's a 96 zj limited 4.0l. Its got the all time 4wd. It has a random miss. Seems to be worst under load and idling. It will die at stoplights.
Unfortunately, it doesn't do it consistently. One trip it'll be fine the next it will run terrible. It seems that if I run it for a long time, it get better but doesn't go away completely. It almost never likes idling at a stoplight.
I've gotten it to trip code a few times, and it's always all of the misfire codes. 1-6 and random (P0300 to P0306)
I've been working on catching up maintenance so here's what's been changed recently:
Distributor
Cap and rotor
Ignition coil
wires
plugs
fuel filter
air filter
TPS
IAC
Crank sensor
Dealt with rear main
replaced thermostat
o2 sensors
Seafoamed it (worth a try even if it might be snake oil)
cleaned the throttle body
Like I said, I'm stumped guys.
Thanks in advance for the help.

The Manifold Absolute Pressure sensor does basically what it sounds like. Measures the absolute air pressure in the manifold lol. It's used in a role similar to a MAF, to determine how much air is ACTUALLY going into the engine, in concert with the TPS the PCM makes a basic guess as to how much fuel to be injected. High vacuum = closed throttle, low vacuum = open throttle. A MAP sensor that doesn't have a good vacuum connection to the manifold will read near atmospheric pressure and you'll run very rich.

[QUOTE=salad;3037401]What do the spark plugs look like? Are there any interesting pending codes? Have you checked for vacuum leaks?
I don't think I have any vacuum leaks, but I will check yet again. As of 100 miles ago, spark plugs looked pretty good. I've changed them a couple times during this adventure with no real change. The only codes that have popped are the misfire codes. Nothing pending. Edit: And the codes that popped when I disconnected things for diagnosis. e.g. oxy sen code.
