RE: Heater problem. I went to home depot and bought a 3/4" brass coupling http://www.homedepot.com/p/SharkBite...FA5/202270595# and a ball valve http://www.homedepot.com/p/SharkBite...2LF/202270560# to replace the stock diverter as a temporary fix. Took 10 minutes to install and works great. I don't do any troubleshooting that I don't have to in zero degree weather!

 

Now I can use nice filthy E85 in my Jeep?!

 

For a little while anyways.

 

ha ha, Nah I avoid all that E10 stuff like the plague as it is. I was driving through Nebraska and they actually offer 87 in 10%E and no E which is pretty cool. Got way better mileage with the pure gas.

 

YUP!!! They know you do too. Go on www.fueleconomy.gov - when you compare gas mileage, look below the mileage and you'll see something about "original EPA estimate"... when you look up the info on why it changed - one of the reasons is the ethanol in the fuel.

It's hilarious that there's this big push for more fuel-efficient vehicles, but they're putting additives into the fuel that take AWAY fuel efficiency... STUPID!

 

Yep. I can only imagine the depth of the clusterf#$% that is the oil & corn industries which has resulted in some Brazil-esque **** like the E85 thing.

 

Before they started adding ethanol to fuel, lawn guys could run their 2 cycle motors for a year without needing to rebuild the carb - now, it's every few months. The fuel is HORRIBLE!

 

Ethanol in the US is a joke for a couple of reasons. Actually it's nearly criminal. Ethanol has a lower energy density than gasoline, so it's no surprise that most vehicles have worse fuel economy running on E10 blends. Certain engines, have actually been known to have economy worsened to the point that the overall rate that gasoline is burnt has actually increased! Go figure huh. The great "environmental" irony is that ethanol burns cleaner than gasoline - this is true - however in the US (and Canada, by extension) ethanol is derived from corn. As you've probably noticed after eating corn on the cob, corn is incredibly tough. To process the sugars into ethanol and break down the fibrous matter, the corn is made into a slurry and cooked in coal-fueled furnaces. So not only are engines using more gasoline, but we're also firing massive coal plants! Yeah that sounds green to me! In addition to this, the whole nightmare is actually driving up world food prices because we're using food for fuel... and world fuel prices because we're using more fuel because the food doesn't burn well enough! (Technically the corn used in ethanol isn't "food grade", but tell that to cows. As well the amount of arable land is very limited and this is a colossal waste of natural resources, and stuff like fertilizer) Literally the only parties that benefits from ethanol are corn farmers, who receive a nice government subsidy to waste gas instead of feeding people.

Brazil, on the other hand, is doing it right and using sugar cane, which is easier to process and much more efficient in terms of resource use to produce a certain amount of sugar (way sweeter than corn...). The US and Canada would be doing the same thing if not for some political bull****. In vehicles that can run it, sugar cane-derived E85 is much cheaper and has an overall lower environmental impact than running pure gasoline or E10.

 

Corn is the most subsidized crop in the US. Always follow, the money to politicians.

 

Got a techie question for the oem, I know my lines, regulator, and injectors are set up for 40 psi or so, but how much can the pump generate? what are the flow/pressure numbers for an oem pump? '88 cherokee-stock in this regard. My master manual says pinching the return line could generate up to 95 psi, but that is of limited use.

 

Probably right at 95.

Forced induction?

 

I am going to run higher pressure, as my regulator will not work withe '99 manifold and rail, and yes, forced induction soon, but I dont want to get stranded (or a fireball) burning up my pump running 50 or 60 psi out of a corvette inline regulator, which, incidentally, costs half of what a renix rail regulator costs.

 

I ran 120 for short bursts using an AFPR on my supercharged Miata.

 

I've heard good things about LII leaf sliders used in place of traditional shackles. Anybody have a long term review of them? I'm curious how long the plastic bushings last and how the product does over time as a whole.

 

AFPR? I know what it stands for, but why not a fixed 80 or 100 or something?

I'm not in the know, I just want to bump up the regulator pressure on my '88 XJ by 10-20 psi, I know to keep an eye on the lines and connections for bulging, leaks and other signs of possible failure, I will be using a wideband to tune for my cam and manifold swap anyway, but I am somewhat new on extensive mods, I don't know if fuel pump constant pressure ratings are typically much higher than their regulated pressures, or what the deal is, is would seem like the higher you could run the better off you'd be, better atomization, higher flow.... And if that's the case my extrapolation begs the question; Why don't manufacturer's run higher pressures?
