Fuel pump location on 1995 S420
 

I replaced the battery on my wifes s420 and it cranks but there is no fuel getting to the engine. I do not have a shop manual for it and am trying to find the fuel pump location. Is it in the tank or on the side of the engine. I am used to working on early model 300sd's and other diesels. I am wondering if it would pay to install a new pump or find amechanic up in st. Augustine FL where it is sitting. Thank you
