I was wondering... Is there any big reason the Walbro boost pump for WVO available on this site [http://www.mercedessource.com/node/2133] couldn't be mounted in the engine compartment, perhaps on the driver's side inner fender for easy maintenance access since there's room there? This car is my 1982 300D. I was thinking about setting it up there on the inner fender, with the easier access afforded, to pull the veggie fuel right out of the hardline as it comes fore and send it on its boosted way to the heated filter (a Vormax unit I scored used out of a wreck for insanely cheap). Would that be inadvisable to locate the pump thusly for some reason I'm not thinking of? Also while we're on the topic, how much noise and vibration do these pumps create, and would that be problematic in the engine compartment? Thanks for any and all input!
