This has been an interesting read, quite an eye opener for me about Fram filters - I've used them religiously for as long as I've been doing oil changes and never had an issue with them. I recently did an engine swap on my '88 Comanche (4.0L), and the issue I'm having is only on start-up. I have a pressure guage installed, and it's taking 3-5 seconds after start-up before I'm getting any oil pressure, and I can hear the engine running dry (rattling) until I get pressure on the gauge and it smooths right out so I know that it's working properly. This only happens when it's left for a while (like over night), if you use it again within an hour or so it doesn't do it, and I don't have any pressure issues once it's going, it's as though the filter is completely draining and the pump has to re-prime and fill the filter every time. I've taken the pump and filter base off and I'm not able to see any check in that section to prevent drain back - is my engine missing a piece, is the check on the discharge side of the filter? I set the pump up in my bench vise and filled it with oil, it does drain down slowly if left alone - I have a spare oil pump that I know is good and I did the same test with the same results, which is not suprising as it's just a gear pump and there will be some internal clearances. Any insight that you guys would be able to provide would be greatly appreciated - the less times I take the oil pan off the better.

Those look pretty sweet - is it possible to get these sent to Canada? Thanks.

Thanks for the ideas, I did find that sensor on TeamCherokee (Intake Air Temp Sensor #17221.01) - but it specifies that is is for 1991-96 models only. I'm not really sure what the difference is but I want to make sure that it will work with my Renix system. I'll give them a call and see what they have to say - if that's a dead end I guess I'll start going through junk yards too.

Hey, I know there are a couple of other forum posts on here about this - but I wondering if anyone has any fresh information. I need to find a new MAT sensor for my '88 Comanche and I'm hitting walls everywhere I go - I've checked all the online places mentioned on here (Rockauto, Tomco, Standard) along with all the local part stores and dealers, everyone tells me that it's no longer available. Any tips you can give me would be appreciated, thanks.

Thanks for the reply, exactly the information I was looking for!

Looking for a little advice here, maybe even a pic or two would be great. I recently picked up an '88 Comanche and when I started digging into it found it to be in worse shape than I thought - slowly ironing the kinks out though. One of the things that I was hoping to get some information on is where the arm for the rear brake compensation valve should sit when the truck is empty - somewhere along the line someone has put on a home made lift kit on this truck and they just strapped the arm all the way up (simulating a full load). I haven't driven the truck much to know if this is causing any problems or not, but it would make sense to me to have it working - if anyone can let me know what the best solution for this would be I'd appreciate it, thanks.
