Converted 300 Tdi with gas fuel filter still

I have a 300 Tdi in a 93 RRC. The mileage has taken a pretty good drop lately and I have been looking at the filter situation. I have changed the one in the engine compartment and when looking under the rear wheel well for the sedimenter it looks like the gas fuel filter is still in place there. After much searching I have come across one person saying they just put in a new gas filter and left it in place, which would be easiest.

I am trying to figure out if I should just replace the current filter, replace it with the correct sedimenter, or bypass it and put one of the cool aluminum glass sedimenters in the engine compartment. I just put a ton of time and money into the Rover would love to not over think this if I don't have to.

thanks in advance,
Craig

Replace it with a sedimenter. The gas filter causes serious restriction. Talk to Robert Davis. He can get you a nice sedimenter.

I've had Rob's glass sedimenter on for 1 week and it already has pulled out a 1/4" of water. That would have stopped a petrol fuel filter in it's tracks. you need a proper sedimenter. The think I like about Rob's is you can clearly see it working and when it's time to drain. I had a Racor, and it was always fogged up, making the alleged transparency useless. Get rid of that crappy petrol filter. It's an Achilles's heal.

The wheel well filter in your RRC is the diesel version. Doug sent it to me and I replaced the petrol filter with it. They do clog up after a while. The diesel ones look just like the petrol with just less restriction.

Everyone else is right. Get the sedimenter from Rob Davis. Much better.

Thanks for that info Jason. I dug around under there looking for any markings on the filter and couldn't find any with it in place. I will have to pull it out and see if I can find any identifying marks for replacing it.

I like the idea of the sedimenter and have had tingly urges for the nice glass and metal ones but I do worry about it in the wheel well. I have been digging around for ideas for putting in the engine compartment but haven't found any yet. My RRC compartment is a little tighter than on the defenders.

thanks
Craig

On my 93 RRC Tdi I put a 12v diesel fuel pump in the stock RR fuel filter location per R Davis on hand persuasion.
He laughed at me while I got my hands covered in diesel fuel.
It's too tight there for a sedimenter.

Ive had my racor in my rear wheel well since 2006, and the bowl is plastic on that. Never any damage to it in all the trails Ive been on.

Heres ny new glass sedimenter. See the water seperated out at bottom?

The paper petrol filter is not diesel compatible and will swell and clog with both water and diesel.
Your engine will always run fuel starved.

Say what they will, but I've been running my D90 300tdi conversion with the gas filter in place and the diesel filter in the engine bay, had to change it only twice in over 150K miles and 14 years now.

When mine starts to get plugged, my mileage doesn't suffer it's my top speed that does. It won't go over 45 mph when it starting to get plugged up. That's when I change the in line stock gas filter out.
I carry a spare with me on long trips, and it hasn't hurt a thing as far as I can tell.

So there you have it. The inline gas filter doesn't hurt...until it does. Then it sucks (figuratively, not literally).

Change that junk out.

So that's what I do, change out the gas filter and I'm good for another 60, 000+ miles.
I'd bet the diesel filter would have plugged by then too if I'd have eliminated the gas filter

My power seem to be about the same. Mileage has always seemed a little low compared to other Tdi reports. I lifted it 2", 245/75-16 tires and a roof rack added and has the correct diesel automatic transmission. I generally get 19mpg around town and 22-24 on the highway.

The guy who built it said he used to get 30 mpg all the time, but again that was conservative stock size tires and no rack. I don't know what you used to get with it Jason? Lately I seem to be down another couple mpg for the last few tanks. Put in new diesel filter in the engine bay and new air filter and neither have made any difference. Power seems about the same though.

thanks
Craig

FWIW, I have never gotten better than 25mpg on a road trip in mine.
My around town mpg seems to be mid to upper teens, too.

And I dont believe anyone who says they've gotten 30mpg with a 300tdi...

You need to be careful as to which gallons people are talking about.

30 mpg in UK gallons is 25 US mpg. 25 mpg is possible, but you need to be driving slow on "normal" tires without roof racks and such.

"I dont believe anyone who says they've gotten 30mpg with a 300tdi…"
This has kind of been my thought as well. I am pretty happy with where I was at mpg wise before but am more concerned about the drop in mileage now.

thanks though,
Craig

You have to be lucky enough to have always used a gas filter with composite media and not the paper style that will greatly restrict the flow of diesel.

With 2 filters, how do you know which one to change?

Excellent point, John.
I guess under some driving conditions you could get better mileage if your engine is running fuel starved with the gasoline filter in place...

This is all US gallons as the truck has always been here in the states. I have played with different driving styles and don't see a huge difference in mpg. The automatic might help mitigate some of the advantages one could gain by driving efficiently with a manual. I get right at 19mpg around our small town, 20 mpg idling along off road in low range, and have seen as high as 24mpg on the freeway, although 22 is much more common.

My Dad has Jason's other rig a D1 with a 300 Tdi and I think I get slightly better mileage than him.
