Default fuel pump/tank conversion

ok, so my first question to try to work from the answer, is what is the difference between a 1990 xj fuel tank and pump and a 1993 per say? i need to install new fuel pump in my 90, but the one thats in there is an airtex unit. i found out that you cannot swap, normally i guess, the pump and parts with a new bosch pump. if i had the oem unit, i guess i could. airtex is about the only full unit i can find to replace what is in there. i DO NOT want to use their crap. I've been to the jy to pull a renix oem unit, but they do not have them there. so, i have come to the point to see what the difference is in the different ones. is there a difference? is it a simple conversion to go to a newer style and use it? if its the tank, how hard is it to convert to a different year model tank, and go from there. any info on this subject would be greatly appreciated. OR, if you know where i can find an oem unit to install, where in the world are they? i will just go with that.
thanks in advance

It's not beyond the realm of plausibility that Airtex, after selling untold 1,000's of crappy pumps, somewhat cleaned up there act. Even without forums like this they must have gotten hit with too meany returns. Next time my pump fails, once again I will just bolt in whatever Napa sells me....

Yeah I'm to the point that I'm bout ready to just slap one of those 2 in there and be done with it. Next question though, have yall ever dropped your tank to drain fuel and clean? Is there a better way to clean? I realize a garden hose is not the prime choice, but the old strainer sock has a bunch of small particles sucked to it, and the gas smells old. I'm actually pretty sure a lot of it is old. Not sure if the previous owner drained the fuel that had been sitting for 6 years before filling it back up.

Gonna order an airtex online. Before install, yall know a good or best way to clean the tank? There was some sediment of some sort in the bottom I guess that was sucked up to the strainer sock. Would like to start with a fresh tank of fuel if possible

With the old fuel out I might use a bunch of dish soap and hot water. Shake rinse, repeat. To finish maybe rice with a pint or to of isopropil alcohol.

If I rinsed with diesel or kerosene...diesel is cheaper, but kerosene is safer, less volatile.

I've usually just used soapy water for my metal gas cans. I even keep a coffee can of 3/4 washed rock (gravel), handy so as I shake it the rock cleans the inside. But that's for a rusted gas can.

Not really. They are so close it makes no practical difference.

The flash point of kerosene runs about 100-160-ish, depending on the source you consult. Diesel runs 100-130 or so. Yeah, it's different. No, it's not much different.

I've used both in a squirt bottle for starting my wood stove. Waz quite surprised to see how sluggish diesel is compared with kerosene.

Oh, hey! Another woodburner! Sole source of heat in my house. I never use any accelerant, though. Just old-fashioned kindling. The hydraulic splitter makes a lot of small scraps, and we just store it in a dry place. Of course, once it gets good and cold, the stove never goes out until spring.

If you ever come across grocery store vegetable boxes, the kind made of wax-impregnated cardboard, grab it. THAT is some serious kindling!

Very true, but neither one is going to flash ignite on you when used as a cleaning fluid.

Here in CA I'll often shut her off at bedtime. Then in the AM, an Oz. or two of diesel on the dead cols/charcoal from a soap bottle by the air intake, light it, and that's it. I confess I can do that without getting out of bed!

Hmm. The wood looks like cedar, but the bark doesn't. Redwood?

I'm beginning to think I should just buy a new tank. After dropping and siphoning all the fuel out, I'm seeing all the crap in the bottom. Not sure how well I will be able to clean it
