1997 cummins 2 tank conversion questions

Postby CUMMINS_MAN » Wed Mar 23, 2011 10:09 pm

Hi my name is Ben Abraham I am 20 and a college student, I go to sc4 (a community college in Port Huron MI), but I will be transferring to Michigan tech in the fall I am going to be a mechanical engineer. I played two years of junior college basketball at sc4 and plan on playing football at tech. Right now I am an assistant manager at an ace hardware and work 40 hours a week and take 15 credits so I really busy, the good thing about the job is that I can get everything at cost. Enough about me…..

When I bought this truck 2 years ago I bought it because I wanted to run it on veggie oil. I have a 1997 dodge Cummins with 220000 on the original automatic transmission (shhhh. don’t tell anyone) p-pump. I would argue that 1997 dodge Cummins truck are the best truck ever built but that’s another topic. I have started on my processing plant and on my conversion. Ill post pictures over the weekend.

My first question is about the hot water heater elements, I know quite bite about home electricity and I know that the hot and the common go to the element its self but my question is can I ground the pipe to a GFI so if there a problem it will blow or is the whole element the common, I don’t know if that makes sense or not.

Why have the elements on the pressure side it doesn’t really make sense to me you aren’t gaining that much heat by having heat right before the centrifuge and I am using a sbc pump so the extra heat shouldnt make a difference I think, tell me if I am wrong.

I am only using 1” pipe so the element might touch so let me know if that will affect the GFI plan of mine I am not sure exactly how the element works.

My other plan with the hot water heater element is to have no metal connecting it to the other parts. I will have vinyl reinforced tubing connecting it to the barrel witch is a coated metal and to my pump and I will have it sitting on a wood frame. Just in case it shorts out.

Thanks for all the help in advance and sorry if it’s confusing or if there a lot of misspelled words I am a horrible writer.

Hi and welcome to the forum.

They make a brass clamp that lets you hook a ground wire to any pipe, ask in the electrical section.

My gear pump is at the limit of its temperature rating. Putting the heat before the pump will make it exceed the limit. Any length of pipe cools the WVO down and I want the max. heat at the CF.

You need a bigger pipe. Hitting it can make a hot spot where the WVO and the heater element burns.
My other plan with the hot water heater element is to have no metal connecting it to the other parts. I will have vinyl reinforced tubing connecting it to the barrel witch is a coated metal and to my pump and I will have it sitting on a wood frame. Just in case it shorts out.

The GFI will already protect against that. Having everything metal connected together is safer since then its all grounded.

I bought aluminum heads. I am going to run the 10 micron water absorbing filter in front of the 2 micron filter.
