Underseat gas tank woes

I do. I brazed a bigger pickup tube onto a fitting and screwed it in the threaded hole. I assume this is the same for steelies, or is it just brazed right on the tank? Whatever. Bigger pickup. I got it. It's cool.

 

Jim,

I can't believe what a ruckus I started! To your suggestion about flat towing and knuckle grease, everyone knows you haul your Jeep on a tandem axle trailer, and only 90 weight oil should be used in the knuckles. That stuff is simple and not open to the interpretation that apparently the undereseat nuclear devices are.

It's an easy change and shouldn't cost more than $100. A real no brainer if you are already doing conversions on your rig. Didn't see it mentioned but I'm happy about having a couple extra gallons of fuel, a real plus if you've gone from a 4 cylinder. I really have noticed the mpg change with my v6 conversion. But I love the power and wouldn't have it any other way.

 

What's the difference between the 4-banger underseat tanks and those for the V6?? Is it a return line or something?

Ha ha JK you certainly didn't start any ruckus. Offense is never intended here; hopefully none was taken.

As far as this goes tho:

The FSM does call for 140wt.

 

All in jest Hippo. As you saw Jim pitched the soft ball and I just hit it! The actual case in the tank outlet is that the 4 cylinder version is identical in every respect to the 6 cylinder version, except for two items:

1. The return line is not accommodated by the 4; and
2. The fuel line tank fitting is for a 1/4" OD fuel line on the 4 cylinder.

My mistake, since I was in a hurry, was not noticing the 4-cyl. only note on the item I ordered. When it showed up and the fuel and return lines wouldn't fit up, I decided to take a chance. It worked well for quite some time. I think the main problem was that the rubber fuel lines began weakening and collapsing. The reason I say that, is that the problem was getting worse, yet nothing had changed with regard to weather and use. live and learn.
