Fuel Pump works but no Power!
Big_Mark replied to Rhys Chalmers's topic in MJ Tech: Modification and Repairs
Great job! These things require tenacity! To make sure I didn't run into the slippery hose issue again, I secured the pump to the bracket with hose clamps as shown below So far so good and trail tested! -
Fuel Pump works but no Power!
Big_Mark replied to Rhys Chalmers's topic in MJ Tech: Modification and Repairs
In my case I installed a new fuel pump and sending gauge assembly. After lots of diagnosis I ended up pulling the assembly and discovered the output hose between the fuel pump and the fuel line had slipped off. So what was happening to me was the pump was working but it was sending most of the fuel back into the tank. I know it's a PITA but you may want to pull out your sending gauge / fuel pump assembly to make sure everything is in place. -
A few months ago I was in the 89 (the right one) looking for misc. interior and dash parts, then I looked up and found my new headliner, cost with extra stuff was $20. Gotta love a good junk yard score! As for the 87 on the left, the 2.5L engine is in there, but most components have been stripped off of it. I might go back and pick up the front bumper but I don't really need it so it's still there (as of 4/23/2023) for someone else that does. Aside from these Comanches, they also have 4-6.5 (It's a junk yard so they have 1/2 cars ) Cherokees 89-98, also in various states of picked overness. There are a few yards near me, and I'm seeing fewer 80-90s Cherokees, let a lone Comanches so I feel fortunate to have this place so near (10 minutes away).

This lives in some bushes in the junk yard known as "All about Auto Wrecking" in Snohomish, WA Very picked over, but has a gray bench seat in it, has a bed no tailgate, no taillights, 6-cylinder engine The Comanche on the right is this one, there are two in the yard.

What about it?

I sold a worse looking set for CJs a few years ago, them things is hard to come by so yea, its a supply demand thing and if you really want a set you either have to be a regular at a yard or pony up the duckets $$

Ordered parts to replace timing chain and gears, rear main and oil pan gasket

CB Radio Mounting Locations?
Big_Mark replied to CheepComanche's topic in MJ Tech: Modification and Repairs
Those mount locations look like they are either in the heater box or close to it. How do your CBs function in there? I am also trying to decide where to put mine, seems like under the dash near the TCU bracket would be a good fit. -
I ran an ignition switch and a separate push button starter switch in my Scrambler. It was handy for "situations" were the starter was required to get through some obstacles I shouldn't have been trying to traverse. Winch + starter + "in gear" kind of things, useful for rock crawler, not so much for a stock MJ. Slightly off topic

I've been thinking about this topic for a few days so here's my take. Safety is relative. You can't rely on drivers around you to keep you safe, so you need to know the limits of your vehicle (any vehicle), safety features, faults, peculiarities, and so on. Part of vehicle safety is operating the vehicle within the boundaries of the vehicles capabilities. For instance I can do 85-90 in my Jeep but I don't, it's got a 6" lift and my timing chain needs to be replaced, either one of those gigs are reason enough not to drive at excessive speeds because, for the lift: the stock geometry is altered. While this is great for wheeling, it's not super for on road performance. for the timing chain: I need to drive like grandma, or at least keep the RPMs under redline until I can address the issue, even with OD getting up to 90 MPH will take some RPMs, so I don't. Also my brakes work well, but not great so I maintain a good following distance and drive defensively in traffic. I discovered these things by working on my Jeep, observing how the car handles and performs, then have adjusted my driving style, for this car to follow suit. I believe if you do something like this with your Jeep you will be a safer driver that operates their MJ within it's safe operational boundaries. Aside from that there isn't much you can do to add safety features unless you want to retrofit an air bag for some feel goods. Other drivers are something we have no control over, the best you can do is stay alert. Like the Drill Sgt says "Stay alert, Stay alive" I've driven "unsafe" cars for years and continue to do so. Fortunately, defensive driving and driving within the capabilities of my rides have done me right, hopefully it works for you too.

I have one with intact fitting on both ends. However but the "brackets" are in bad shape. If you want it it's free (except shipping) p.m. if interested

I'll look in my parts bucket, I think I still have one.

It seems odd that you would have so many defective radiators, I know you're discouraged enough but if you have a bad head gasket blow by could be sending pressure into your cooling system, causing the radiators to fail. You indicated there is a lot of oil coming from your engine, this can also be a sign of blow by (more likely rings than radiator for oil). Sorry to add more to the pile.

Found during valve cover gasket install

That's the widget right there! If mine wasn't working I'd buy this one -
Found during valve cover gasket install
Big_Mark replied to NC Tom's topic in MJ Tech: Modification and Repairs
It's a vacuum driven "servo" that opens and closes the flow of hot coolant to the heater core when you move the heat/air/etc. control in the cab. My money says nothing happens when he moves his lever -
Recommendations for Speakers
Big_Mark replied to Warren99's topic in MJ Tech: Modification and Repairs
That's what I just did, sound deadening, friggin headliner is in and it does sound and look much nicer. I picked up some tweeters from the junk yard the other day, and plan to pop them in this Summer when I install my rubber floor mat. I tried installing the rubber floor mat but here in WA in Jan it was too cold, so for now I'll just run 4x speakers and work on other items -
Recommendations for Speakers
Big_Mark replied to Warren99's topic in MJ Tech: Modification and Repairs
I just installed these. Doors - JVC CS-DR521 speakers fit behind door panel if you leave the JVC grill off. B Pillar/rear - Kicker 46CSC464 speakers I like em! BTW I had to run new speaker wire to 3/4 speaker locations so be prepared! -
I'm going to include vehicles I drove and maintained for 3 years in the Army since thats when I started driving on a regular basis 198* Chev Blazer 3/4 ton Diesel - Army (US) AMFL, Manheim Germany 197* - M577 APC - Army (US) AMFL, Manheim Germany 1989 Ford Ranger 4x4, 2.9, Rancho 2.5" lift, Borla Header 1982 CJ8, eventually this became a trailer queen rig with Dana 60 f/r 6:21:1, 35 Spline, T18, blueprinted and balanced 5.0 from 1987 Crown Victoria, dents 2006 Chevy Malibu Maxx SS 1984 Toyota Corolla "the Bucket" 1989 Discovery 2 "the tin can" These thing are so flimsy I had to sell it, there is a reason all the "Camel Trophy" photos from back in the day show guys unsticking these rigs! 2006 LR3 "the money pit" 1992 Honda Civic "the stolen car" 2010 Toyota Prius 2015 Chevy Silverado 1989 Jeep Comanche 1969 Mustang, Mach 1 - My Uncle bought it new, we've resto-moded it with an SVO Crate 351, Holley fi, suspension, steering, more - it's loud and goes fast So far that's where I'm at!

Hi gang, I have finally rewired my a/c pump to an in-cab switch so I can repurpose my unused a/c pump for on board air. The next thing I need to do is plumb in a hose from the output port on the a/c pump. which will either be plugged into an auxiliary air tank (under the bed I think) or directly to a hose to fill my tires after wheeling. Unfortunately, I "cleaned up" the stock hose so now I either need to replace it with a "new to me" one (junk yard run) or, better yet have a custom hose/pipe made so I can bolt on regular air hose couplers. Can anyone tell me what hose fitting size and type is used on the circled port below? Thanks!
