I am considering using this between the hard metal fuel line in the engine bay and the clear filter to help assist the flow of the oil and flush the air out when filter changes are done.

How much pressure would be necessary to help assist the WVO thinned with 10-20% RUG? Would 7-9 PSI be too much?

Hey Curtis,

I know a guy with a 84 300SD White in color, tinted windows & factory wheels that have been chromed. It's really his wife's car(Carina).....anyway they have been using that fuel pump for at least 18 months & over 16k miles now and is still working great. I can give you there PH# if you need it. Hope this helps.

me too!

I'd like his ph#!

I should put a pump on to save the IP, at least that's what I heard, and I don't know about the pressure, etc, even though I read a ton of posts.

If he doesn't mind that is...

i know this is and old thread.....but, aside from the lift pump issue, has anyone had serious issues with the greasecar conversion? any reservations on recommending it to anyone else? i am still debating on building my own or just buying a greasecar or frybrid. id still like to hear people talk about their experience with the greasecar conversion.

Other than adding the aux fuel pump from GreaseCar - which I now think was unnecessary, but still a bit of added insurance for the stock lift pump - I've had no serious issues with my GreaseCar system except than the fuel tank venting issue which causes me to have problems switching to WVO when I've just filed my tank.

This is my hypothesis:

Because of the way GreaseCar vents the tank through the cap, it is very easy for those tiny vent holes to become blocked and then a vacuum builds inside the tank. That vacuum then literally sucks the fuel back down the line when the car is either stopped or running on diesel. When I try to switch to WVO, the car will die, then restart on WVO just fine. I am not experiencing this problems as much as I did before, but it still happens from time to time. There are a couple remedies I've read for this problem, but I have not tackled it yet - I'm still hoping I can find a way to stop the vacuum from building without having to drill into the tank for a release valve.

Otherwise I have no real complaints about the system. I did augment mine with a VegTherm Mega (electric fuel heater) from PlantDrive and now I can switch over to WVO much sooner than I could - so now I'm burning more WVO and less diesel. That works out well since I have about 80 gallons of WVO in the garage - and more being delivered to the house on a regular basis.

thanx for the reply. do you know how the other kits are venting? i hope to get this converted before i move to denver in the spring/early summer. that might give me a couple of months to tweak it all out before the winter hits again.

No, I'm sorry I don't know how the others are vented.

On a somewhat different note, I just realized that the lady who regularly drops off WVO at my house left a whole cubie of brand new canola oil - unopened!! Crazy, huh? I guess she or someone at the market must have picked it up by accident! Oh well!

Wait a second. You get your WVO home delivered? I thought I had it good just getting it in the cubies from the bar, but wow to the door service is unbelievable. Maybe you can talk her into filtering for you too

Yep - there are two other WVO drivers here in Las Vegas who bring dirty WVO to my house and then fill up with filtered WVO in exchange. One is the owner of a Japanese restaurant (their daughter drives a WVO Jetta) so they bring me several cubies of used tempura rice bran oil every week, and the other is a lady who drives a WVO VW Beetle like my wife's car so she picks up used canola oil at a market/bakery and brings several every week. They don't have the time/space to set up a filtration system at home, so they just bring the WVO here and use mine - and I get home-delivered WVO to boot!

Venting, Frybrid Thoughts for comparison

The Frybrid tank has a vent line coming out of top of tank which I just routed to under car.

Im just now finishing up Frybrid install on my OM603.

So far, Im reasonably impressed with their kit.

What I think Frybrid offers over Greasecar :

- 2 3port valves made of metal, very durable. Greasecar uses Pollack plastic 6 port, from what I hear its not very durable
- Since Frybrid uses 2 valves, they have 2 completely separate systems for diesel and WVO. There is a time lag between the 2 valves during switch back from wvo to diesel, so you don’t get ANY quantity of WVO into your diesel tank (ie, no growing diesel tank). Very important for longevity of engine to have completely separate systems.
- Computer to control switchover / purge – VERY foolproof, if you need it. If not, overkill.
- HIH lines – I was skeptical of this set up at 1st, but Im well impressed with how much heat it can transfer.
- Aluminum tank with local heat exchanger requiring only the fuel near pick up to be heater, rather than entire tank. Makes for quick switch over – important for people like me who make short trips.

Problems with Frybrid –

- Im not impressed with customer service at all, or install instructions. I cannot seem to get in touch with them for the life of me. Phone or email. So I have to post on their forum. They usually answer 1 time with 1 sentence reply and that’s it. You are on your own with them. Sounds like Greasecar might be better about helping.
- Kit not well designed for installation in my 87 300D ---
o Tank too wide to fit in trunk without modification (this, after COUNTLESS emails telling them exact width!!)
o Kit came with 3/8 fuel hose, 3/8 valve fittings, 3/8 filter fittings. Great, but my OM603 diesel filter housing, diesel pre-heater, diesel intake and return hard lines, and lift pump are all 5/16. They supplied no provisions for any 5/16 fittings, or method to interface 3/8 valve fittings with aforementioned 5/16 fittings.
o No 5/8 heater hose supplied – but you need 5-10’ of it. No biggie, but for $1800 give me what I need.
o No instructions how to route HIH to trunk. Very tricky on this vehicle to do correctly (meaning, not routed in between moving suspension components!)
o Final heat exchanger the size and weight of a cinderblock. Not suited for tight confines of OM603 engine bay at all.
o IDIOTIC hose clamps for 3/8 line. Unless you feel like spending a half hour on each hose clamp, you need to go buy different ones. Unacceptable in $1800 kit.
- 2 month ship time
- My tank came untapped for the fuel sender. Required me to have machine shop drill, tap, install sender in tank. I paid this out of pocket. Unacceptable in $1800 kit.
- No provisions for mounting WVO fuel tank – although I think most kit builders are guilty of this. Laying it up against vertical diesel tank would be disaster in a front end collision. The WVO tank would squash the diesel tank and could ignite the whole car. Honestly cant believe ppl are not more concerned with this.
- No provisions to mount final heat exchanger, WVO filter housing. Had to fabricate brackets – again, this should be included. Although Im not sure if any kit maker provides this.

As for your questions about plumbing – yes, the lift pump should be last thing in line. It should feed directly into IP. This means you need to re-route plumbing such that diesel side goes from tank, directly to diesel filter, to diesel pre-heater (if your model is equipped), THEN to solenoid valve, then finally to lift pump. Note that you are now pulling diesel through the lines all the way to lift pump, rather than pushing. Recall the factory set up is to pull to lift pump from tank, then let lift pump push through diesel fuel filter, heater, and then on to IP. In my opinion, its much better to push rather than pull (pressure rather than vacuum) because vacuum will draw in air. Air will stall motor. Pressure would just leak fuel out, no big deal (and easy to spot!). So…route lines like Ive said, and also you need to test for vacuum leaks. I did this with a mitivac hooked into lines, took many re-do’s to correct all the vacuum leaks.

Nice write up. Greasecar I think used to use the Pollack but they definitely have not for at least 1 year. They have their own custom built 3-port solenoid with viton soft parts of which 2 are needed to install the kit. This of course is nothing to say about their reliability, but so far they have not failed on me in about 2-3K miles of operation. No idea longterm.

Paul,

The 5/16 lines are not a problem. You cut off the existing lines about 1/2" past the hose barb and slip the 3/8" lines over the old line stubs.

^ i'm sure that works fine, but for that kind of cash you'd think they could just supply 5/16 line and fittings. you know, a kit somewhat designed for the vehicle.....

i have a walbro 6000 series pump, works great so far, but it is on my cummins, which i only have 1k greasy miles on.

frybrid now sells a fass pump w/ a 2 yr warranty for veg use. $$$

They could supply 5/16" line and fittings but it wouldn't flow as well and you would risk damaging the barbs on the Mercedes fittings when you tried to remove the stiff factory lines. After converting several Mercedes, I compleatly agree with Frybrids choice. But I think that their documentation as a little vague on this point.
