Ditching all the Rover gasoline system & building a heavy duty diesel fuel system to feed the new 4BT Cummins engine. Started by tearing out all the old hoses & emissions junk, then dropped the tank to wash it out but it was spotless inside, thankfully had a hand from some good friends to manhandle it. Next up was running lengths of stainless braid covered & teflon lined AN hose, with -8AN (~1/2") for supply & -6AN (~3/8") for return. Then I got another chance to learn a bunch (& drool over cool machinery) with a machinist friend who helped be bring an idea to life for a replacement fuel sender cap. The old fuel sender has a pump & level gauge that's of no use for me anymore, so we made up some aluminum straws & threw in a reed style level gauge. Before I locked all the hose in with my new brackets I made sure to leave a bit of slack to service the tank while it's on the ground, sure beats trying to get wrenches up above the tank to get it free. Welded my new hose brackets onto the frame to secure the new hoses & protected them where necessary. Check that system off the list!
~ PART#20 in a project dubbed "Nanuuq" to swap out my lifted Land Rover Discovery 2's blown 4.0L V8 & boring ZF auto for a Cummins 4BT 3.9L turbo (Holset Super HX30W) diesel 4-cylinder engine (Bosch P7100 pump) with an NV4500 5-speed manual transmission. The AWD 4x4 will remain with the LT230 transfer case divorced behind it all, & plenty of Dodge 6BT parts too. Another big phase of my custom DIY build to create a do-just-about-anything off-road / overland rig. Did I mention it's a camper too?

NOTE: Fuel filter is up by the engine, a screen before the lift pump & a filter/water-trap after it, all before the injection pump. Also I may add an aftermarket prefilter setup, but not yet since I'm not sure whether or not I'll utilize bio or waste oils with this build.

I too just watched all 20 episodes. This is a long process and its great to see you're committed to get it done and done correctly. I like what you've done so far. I've been thinking about a 4BT swap into a Jeep TJ and watching your series and a few others here on RU-vid have really given me the itch to start. Your videos are very informative and amusing keep em coming.

Thanks & yeah it looks much worse than it is thankfully since the back of the truck sits over a part of the concrete floor that always sweating so the rust just rubs right off with the dirt. But I'm going to scrub it down & slather in a special coating before too long.

For sure! I'm waiting to finish the swap & then I intend to restore the whole frame & all the brackets. I'll gently sandblast everything & spray it with some fancy stainless steel flake spray, & then wax coat the internals. The frame used to be so pretty, it just took me way too long to figure out the moisture issues in that shop :(

@Bread996 6 лет назад

In my experience. Install the rubber seal on the tank first, then push the sending unit through it. The first time I filled my tank fuel overflowed all over the ground. I would check that because it didn't look seated in the video. I also found that aftermarket sending units would not allow the guage to read correctly. At least in 2003 Discovery, the guage needs a 15-251 ohm range whereas most aftermarket guages are 33-240 ohms and the gauge will never read past 3/4 tank. I had to attach the land rover sending unit to my diesel pickup assembly.

@Tinker1837 6 лет назад

Good looking out, but that clip of me tightening the ring over the sender was just for the video edit, because I ended up having to get a second set of hands to secure the 2 retaining clips. I had it all greased up so it wouldn't bind up as I got it threaded down proper & verified the installed height using a measurement I took off the old sender. And I'm not using any of the old gauges, she's getting a complete electrical overhaul from front to back (dual jacket tinned wire, weatherproof deutsch plugs, breakers instead of fuses, dual batteries, etc). So this new reed-style level sensor is more of an upgrade than replacement vs the float-arm style, will read way more accurate while off road!

@Bread996 6 лет назад

Ok cool. It was embarrassing having my tank overlfow at the service station so didn't want it to happen to anybody else. The one benefit to a factory style pickup assembly is that the cup on the bottom holds some fuel, preventing it from sucking air when making corners or driving up a slope. Nice on the electrical work as well. I don't know why I've wasted so much time on my build making the factory gauges to work. Didn't want to bother making a custom cluster, but realzing now in the end that would probably have been easier.

@Tinker1837 6 лет назад

I appreciate the insight though! I love all the advice coming from strangers here & on forums, always trying to stay flexible with outside input on a project like this. And I have no doubt I'll have some embarrassing moments when I fire this thing up, forgetting things & all that.

@xArondightx 6 лет назад

Anytime I see a fuel pump removal I have PTSD from replacing the pump on my XJ. Your sending unit is beyond cool, is there a reason you didn't use a sending unit from a 200/300 TDI? I believe they use the same fuel tank as the V8.

@Tinker1837 6 лет назад

Clifton Rodgers That's no kidding, can be a serious pain! Thought about trying a TD5 sender, but as it turns they use an in-tank pump as wel,l so I'd have to chop it up too. The new 4BT setup has the 1st stage of fuel pump mounted on the side of the block, instead of in the tank, & actually runs off of the camshaft with a rocker arm of sorts.

@xArondightx 6 лет назад

Was actually referring to the 300TDI which uses a similar engine mounted mechanical fuel pump. Yours actually looks like a much better design than the OE unit, I just figured the only advantage would be a working level sensor.

@Tinker1837 6 лет назад

Clifton Rodgers Ohhh okay now I'm with you, & that would've been a good option if I was using the old gauge cluster, probably shares the same ohm range for the gauge mine has. I went with a reed style level sensor that'll work with most any aftermarket gauge, think I found a series of gauges that'll cover everything I need. Plus it should do a much better job at reading levels accurately when I'm off road vs the float arm variety. Although I do wish my tank had a drain plug like I see most the Defenders have!

Thumbs up to all your work but if I may... I definitely wouldn't cure any paints or coatings in your oven that you use for food. There are harmful byproducts that you can't remove from the oven once you have done so. I always keep a second oven in my garage for this reason. I would move your kitchen one out to the shop and replace it.

@Tinker1837 5 лет назад

Thanks & good looking out! That appliance needs replacing altogether & only the range top is used, so the oven goes unused with no danger to cooking. Only used for parts on rare occasion.

And how does that fuel level sensor works ? Also the fuel pump is in the engine ?.old school pump right ? Isnt it better to update it to N elictric one ?

@Tinker1837 5 лет назад

It uses a series of resistors & a magnet in a linear movement, so it's more compact & accurate for an offroad vehicle versus the swing-float style. The engine has a camshaft driven high-volume low-pressure "lift pump" to draw from the fuel tank, then the high-pressure injection pump takes it from there to the cylinders. Very simple & dependable non-electric system 👍

@NeoB-Lac 5 лет назад

Can I take you my 1965 impala so you can do new brake system like the other car and fuel like this? Lol

@Tinker1837 5 лет назад

That's a beauty of a car! I don't think I'll ever go back to hardline after learning to work properly with AN hose. It's just so easy to work with & longer lasting. Well worth the slight added cost when it's a project that goes thru extremes or changes often.

@NeoB-Lac 5 лет назад

What does the - in -8an mean?

@Tinker1837 5 лет назад

As far as I understand it is a suffix meant to be attached at the end of the fittings number in 1/16" increments. So if you had some fitting with the part 999, then the fitting for 1/16" inner diameter pipe would be 999-1. Then each "dash number" up is another 1/16" larger, so 999-4 would be a 999 style fitting with a pipe size of 4/16" aka 1/4", or in other words a -16AN size is 16/16" aka 1". It's clever once you realize! Leave it to military & aerospace to come up with that 🤓

To remove the fuel pump & install a simple fuel straw & a better level sensor, since the 4BT is all mechanical & has a camshaft driven "lift pump" that does all the work drawing from the tank.

94Discovery Nah, no need, an electric pump in there can't reach any lower than the straw I have (which is only a 0.25-0.5inch / 6-12mm from the bottom). Well, if I started chasing huge power with compound turbos & big injectors then I'd want an added in-tank pump, for the extra flow.
