Over the last few weeks/months, I've been collecting parts from various vendors in anticipation of making some improvements to the truck. Now that most of the parts have arrived, I've parked the truck and began the work. Here is a list of the mods I have currently planned:
New Spectra Fuel Tanks
Westin Step Bars
HPX Crossover Line
Tru-Cool Max Trans Cooler
Upgraded (larger) Trans Cooler Lines w/ Bypass
Fuel Line Check Valve Delete Fittings
New Water Pump
203 Degree Thermostat
Tony Wildman Tunes
Trans Fluid Replacement
Yesterday, I removed the stock trans cooler in preparation for the Tru-Cool. This unit was recommended to me by Cary @ CT Performance. I decided to eliminate the stock unit all together over concerns that it may not be working correctly (due to becoming restricted), which would ultimately limit the effectiveness of the Tru-Cool Unit. Besides that, I can't imagine that it would be at all necessary to keep the stock cooler considering the capabilities of the Tru-Cool.

Last night, I removed the front fuel tank. I wanted to shift over to this task so that I could inspect the tank internals to see if I needed to order more parts before the weekend. Happy I did! I got the tank out and inspected the sending unit and pickup screen, which all appeared to fine. Upon closer inspection, though, the pickup screen is missing the small red siphon valve/fitting that goes into the side. So in other words, fuel was getting sucked in through a large hole in the side, not the bottom of the foot. I think this could create cavitation and turbulence in the fuel flow, which certainly could affect performance and fuel efficiency. I get better mileage out of the rear tank, which I attributed to a leaking front tank. While I still believe that to be a culprit, the broken pickup foot likely doesn't help either. So...I'll get 2 new ones on order this morning. For the new tanks, I painted a coat of underbody rust preventative on both sides, actually, 2 coats on the bottom. I think this is merely a helpful measure, but paint rarely adheres well to galvanized surfaces over the long haul. I cleaned the surface off with denatured alcohol, so that should help. I live in the south, and this truck came from the north. It's gone 18 years on the original tanks, so I'm not real worried about it rusting out again.

Spectra Front Tank F6C (price has gone up since I bought mine)
I put the sending unit into the new tank so that it wouldn't get damaged.
The existing tank, when removed, had about 7 gallons left in it. That was/is a little concerning to me, considering that the dash gauge read about 1/8 full. I checked the sending unit in the tank before I removed it, and the screen sits at the bottom, while the float assembly does indeed rest on top. The float actually goes down maybe 1/4" into the fuel, but that shouldn't be causing such inaccurate gauge readings. Any thoughts on this???
And here is a picture of the parked truck, just waiting to be back on the road again!
EDIT: I could literally beat the PO for installing the 5" exhaust. That's a huge pain in the rear to work around under the truck. Those dang long clamp bolts are tearing me up! But otherwise, its a sweeeeeet exhaust
