can I just say ouch?
that surge tank is pretty pricey.
what makes that one better?
It works very well, is compact and easy to install and hook up.
When compared to the alternate method of buying a custom baffled tank and fuel pump. The cost is very reasonable, and the surge tank system offers a much greater resistance to cavitation than any of the tanks I've see offered on-line. The only tanks I've seen that even come close to having a functional anti-slosh baffle system are high dollar fuel cells for road race cars, and those are way more money.

Oh, I thought you had compared other fuel surge tank setups.
you are right, compared to setting up a gas tank it is simpler. but seemed very pricey compared to some of the sealed versions.
I may look at figuring out how to make one cheaper. lot of leeway on 400 bucks material wise.
Oh, got it. On that note, I didn't see a lot of alternative surge tanks out there. There was a nice one from Japan, but the shipping time was huge, so was the price. Less expensive, home made versions are available, especially if you go with an externally mounted high pressure pump. If you can weld aluminum, you can make a nice tank. Finding a fuel tight electrical connection for an internal pump is a bit of an issue. With the Radium kits, it's a nice package.

This is all great stuff, but what I was looking for was trying to grab a bunch of stuff from the junkyard and making it work on the cheap, as a challenge. If possible, that means stock engine, stock computer (not reflashed, if that's possible), stock wiring harness with maybe a few changes, and as minimal fuel pump and tank stuff as possible. That's why I was interested in the 95 Grand Cherokee, because according to the article I linked to, it had returnless fuel injection, which, with my minimal understanding of fuel injection setups, means you don't have to plumb a return line to the fuel tank. I'm happy if the thread just keeps on going the way it has been, because I'm learning a lot, but that was not the reason I started it.

Educate my on what returnless means. My understanding is that a return line to the fuel tank is required if the pump always runs at the same pressure, so for low demand conditions, such as idle, a lot of the fuel is shunted back to the tank. If it's returnless, then there must be some way of varying the pressure coming out of the pump; maybe the pump has a variable frequency drive motor on it. If it's returnless, why do you need to use the donor vehicle fuel tank and pump? Aren't aftermarket variable pressure pumps available? I know it seems like I am reversing my position about using stock junkyard items with this comment, but it might save money (and it definitely sounds a hell of a lot easier!) to buy an aftermarket pump rather than the fabrication work of trying to fit some other vehicle's fuel tank in your car.

I'm glad this kind of stuff has been done before, successfully. I want to stay as stock as possible, mainly for the challenge of doing it as cheaply as possible with junkyard parts. (Mr. Ehrenberg, are you listening? THIS WOULD MAKE A GOOD SERIES OF ARTICLES!) What I'm envisioning is the engine with all the fuel injection parts, overdrive transmission, engine computer (separate transmission computer? I don't know), and harness from a single junked vehicle. As far as the fuel tank, pump, and return system, there I am open to customization. <snip>
Well, I did do the '62 Savoy / 360 (425 HP was a cinch), and gave lots of hints and tips for pure-junkyard swaps, and did more of the same with the 360 '96 Dakota.
Just a few key points...
> The '96-up PCM (JTEC) is way better (and smaller, etc.) than the old SBEC, plus is it "flashable". But, to use an AT PCM, you must have a 46RE trans or you'll be in limp mode. The solution, as mentioned above: Use a junkyard MT PCM. SCT tuning may fix this w/o a PCM swap.
> Cutting up a boneyard harness isn't hard, but you'll need the appropriate FSM.
> Remember that 360 Magnums, while still externally balanced, are "less" imbalanced then the LA360. Plan damper and flywheel or drive plate accordingly.
> Remember that the '92-93 exh. manifolds are by far the best, and all 2000-up 5.9Ls had the "best" cam (same as GC 5.9L ltd / Dak R/T)
I've been doing EFI swaps for almost over 15 years. Way to go. Frankly, the Magnum is getting kind of "old", most guys, today, would rather use a 3G Hemi, and that logic is hard to argue with, esp. now that Megasquirt can do it all, even VCT, COP, etc.
Overall, this is an absolutely awesome swap! Especially great if you're replacing a dog TBI in a truck or van....a real eye-opener.
