Hi all. 

My conversion includes a lift pump to help with the wvo from the main tank . It is located in the engine compartment before any heating takes place . 
I want to replace the pump since it is a Subaru  petrol lift pump and i dont want to wait for the day it will stop working . 
Any recommendations on one? I have been looking on two on the web :

Also should i change the location of the pump to be closer to the fuel tank?


Thanks

Obviously one of those pumps is much less expensive. I have not personally used that one but am considering doing so on my next conversion. I have used the more expensive one but only because it can produce a higher pressure. There have been a number of reports of it failing after a few years and I have in fact had one of those failures. But in fairness we cannot compare reliability since few are using the less expensive pump and so there is not a large enough "sample" for accurate comparison.

Do both of them produce enough pressure for your engine?

Changing the location of the pump would depend mainly on what temperature the fuel is at the current location. There is a balance that must be created between warm enough to be easily pumped and cool enough to not cause the pump to overheat. 

Do you know how warm the fuel is at the current location once the engine is at a stable operating temp?

Hi Dana,

Thanks again for replying, 

I do not know the pressure of the engine, i am using the lift pump just to help the IP with the thicker WVO. I guess i don't need such a high pressure . I have a 96 2x4 toyota hilux 2.4 engine (4 runner in the US).

As i mentioned the pump is located straight from the fuel tank before heating of the oil takes place . never measured the heat of the engine compartment air but the pump is warm to touch. I thought of changing the location  since i read it is easier for the pump to push from close the fuel tank rather then to pull all the way from the engine area. 

Is there any pump that is VO tested?

Thanks a lot

The more i read on the web the more i am having  difficulty to decide which pump i should get. Any other pumps that are proven to work with VO? 
How do you tell how much pressure to adjust it to? 

Do you think one of this transmission oil pump could be a good idea?

Also i have read some info here about mist washing which is something i have never done before but am considering to try. couldn't find a page that describes how exactly to do it? Is there one?

I have not used that pump nor heard f anyone else using it so you would be the primary experimenter. I suggest doing a thorough internet search and contacting the seller to see if anyone else has tried using it. 

As for the mistwashing info go to  http://voconversionbasics.forumchitchat.com/post/Basic-mistwashing-info.-1883553
