veggie kit filter replacement problem

Hi ya all, I just bought an 85 300d turbo that came with Lovecraft, or as u guys called, Lovecrap kit. The fuel filter started to clog, but I'm not ready to ditch the kit since it's still summer n since it ,most of da time, avg above 32 F in Winter around here. I'm planning to modify it here n there n step by step.
Lovecraft is no longer around, so I can't get this filter anymore. Many people here said Davco 234's filter can b used in place of this old Lovecrap one, but I compared the picture online with what I can see through the clear plastic of mine n they don't seem to match. I figured there's not enough time in this life 2 figure everything out on ur own, so I choose 2 get an advise from wise guys here. So any one has encountered this problem, please let me know ur solution
Thanks in advance.

How does the motor run? No stuck rings yet?
Best you dont worry about the filter & put some extra preheat on it.

their infuriating celebrity encrusted, car destroying, over hyped web site is still up. Are you sure they are not around?

Not sure what a good replacement filter is for lovecraft, benz that continue to run those systems rarely make it this far across the country.

If everyone says that davco 234 works, you should order one and see. In the meantime, you can burn diesel and get a fram G5 from an auto parts store and just bypass the lovecraft filter temporarily for now if you need the car daily.

Personally, I would get rid of the entire filter assembly and buy a heated Racor.

how hard would it be to put on a plate heater, and pick up a decent high volume 5 micron filter head?

If it's the early Lovecrap system it uses a Davco filter. Clear bowl on top.
If it's the later system you clean the filter element (clear bowl on bottom).
Add more heat.......

After a while that fuel filter is going to be the LEAST of your worries.

Even with a plate heater. On a cold start you've got an injection pump and injector lines full of cold VO. That's what's gonna kill the engine. I run VO but I'd never run a Lovecraft kit. The only heat they put on their systems it coolant heat. When means your running cold VO until you have hot coolant. This equals death. I'd STRONGLY advise you to get a 2 tank system or at least blend your VO with the single tank system. It's only a matter of time before you're having engine problems.

I worked for Greaseworks for a while. And we spent a fair amount of time thinking about how you could do a single tank conversion long term. You'd have to have injector line heaters that come on before you start the car, and an aux pump with electric heaters in a loop with the injection pump that would heat the oil up and pump it through the IP with the engine off. Once it circulated VO and heated it up, then you'd start the car. So you'd still have electric heater and at least one 3 way valve. But you still have a tank full and fuel lines full of cold VO. The filter is also going to need electric heat. The filter is the biggest stopping point when you have cold VO, and you have to heat it far beyond the gel point to get it all back into liquid once it's gelled up.

I'd also like to note that even on a really hot day here in the PNW at 100*F VO won't burn completely, so even on a 100 degree day the first start of the day you oil won't burn properly. And at

Gather it, filter it, heat it, filter it again to 1 micron, put it in the tank and go.

IT DOESN'T EAT RUBBER.

IT DOESN'T CLOG YOUR ENGINE.

YOU DON'T NEED A KIT.

IF IT GETS COLD, MIX IT 50/50.

I HAVE 4 MBs RUNNING ON IT.

Here we have exactly why Lovecraft has left so many dead MBs in southern CA. I run VO too, and im gonna say the only totally true thing here is that it doesn't eat rubber. Otherwise this is just more of the same "its working now, its gonna work forever" mentality. Id rather put some time into modifying the fuel system so it does work forever.

These unilateral statements are just as accurate as "VO will destroy your engine"

What do your injectors look like? What do your combustion chambers look like?

You don't have to be smart to dump WVO in your tank, but you do have to be smart to rebuild a OM617... So i hope your up for the challenge one day.

Look up 'blowby'. Before the engine is warmed up, combustion gasses and uncombusted fuel leak into the crankcase, OK if it's diesel, VO in the crankcase can cause other problems.

One reason that people use a 2 tank system.

Consider a Racor, or even a cheap low micron spin on filter. 35-40$ for a filter block and a filter. Should do the trick.

Consider adding a second smaller tank for the purpose of diesel/ Kerosene/ Biodiesel purge. This will require additional fuel line and switching valves, but well worth it in the long run.

Moon has a good point, ie: crankcase contamination. I am not fond of the fact that my engine oil is black immediately. I am considering installing a CF to polish crankcase oil while driving. If this removes the suit from the oil, I will be happy.

Oil analysis will tell the story.

VO will polymerize and form a chicken skin in a fuel tank, if it gets in the lube oil (hasn't happened to me) it's said to form crankcase mayonnaise.
