Hi

can anyone tell me what pump is used on the European 3.1Td Grand Cherokee (2000) - I think its a Bosch .. possibly VP37 ??

Anyone had experience of using SVO ( Straight Vegetable Oil ) in one of these - if so a what ( if any) adapations / %

I don’t know if the 3.1L TD came with the VP37, but I’m 99% sure the 2.8L CRD did. These are the same pumps the VW TDIs are running, so the pump is all right. Just check to see if it really is a VP37.

Why do you want to run SVO in your Grand any way? Why not go straight to BioDiesel. Saves a lot of fab work, as in adding two tanks, heat exchange and all of that crap. I know its easier to deal with once its installed, but SVO can cause engine problems. I run BioDiesel in my Dodge RAM, and its yet to have a problem.

Do you make your own BioDisel?

I was looking to see if how it would run with single tank ... maybe just adding a heat exchanger

Out of interest - I tried to get info from dealer - unable to confirm actual unit make version BUT replecement cost £1784 ( $3500 !) unsure if that includes sales tax (VAT)

Hi
Should say on the side of the pump, i Know it's a bosch pump but not sure on what system and I don't have one on site for me to go check. Premium quality diesel fuel with a minimum Cetane rating of 50 or higher is required going by the info I can find.

Hi

can't make out what the engraving says but having looked carefully/ at websites sure looks like the vp37 / EDC.. although of course feeding 5 injectors .. don't think this 3.1 5 cly was used elsewhere

merlintec... whereabouts are you ?.. in a dealership?

No don't use straight veg oil it will leave heavy deposits in the combustion chamber.

When you get your pump out check to see if it has rubber o-rings/gaskets. Some rubber types are biodiesel compatible but most are not. If not then it probably means that the rest of your fuel system isn't biodiesel compatible, in my experience, I would run a 20:80 mix of bio to diesel. Find out if your system is compatible, I hear that you can get conversion kits for some vehicles?
