Hey if you guys have been following along you know I swapped a 460 into my '91 F150 in place of the 300 Six wheezer. One thing I had to do was use a remote oil filter since the factory oil filter hit the crossmember. Anyway about a week or so after I got it running it blew off one of the hoses to the remote filter. Luckily I saw the gauge at zero right after it happened and only went about a block or so before I pulled over (went back later and scoped out the oil slick on the road to recreate the particulars of exactly when it let go). Well since then I have been paranoid about another hose coming off even tho I replaced all the sorry clamps that came with it, but I drive around with my eye glued to the OP gauge. I remembered that my '90 F150 had an "engine" light that came on if the OP was low or the temp was high. Well it seems Ford deleted this little attention-getter on the '91 trucks with gas motors.

The good news is that there is a little module on the back of the instrument cluster that controls the light and I was able to just take that module off of a '90 cluster and screw right onto my '91 cluster, add the light bulb, and viola! I have an engine light on my '91. I tested it by pulling the wire off the OP sender while the engine was running and it works perfectly.

This will make me not have to watch the OP gauge so closely anymore, maybe I can enjoy just tooling down the road with my hand slung over the steering wheel without a care in the world like I used to. A little thing, I know, but thought maybe somebody else might want such a light on their '91.

 

Good info! Also, if you want a bit more peace of mind, go have hoses made for the lines with crimp fittings at a hydraulic store or the local Deere dealer. No more worries about blowing a line off.

 

I've taken a step in that direction, I have all the stuff to make braided hoses with AN fittings, just have not put them on yet.
