1998 Mitsubishi Eclipse 420 A Fuel Pum & Filter Locatio

Engine Performance problem
1998 Mitsubishi Eclipse 4 cyl Front Wheel Drive Manual

My 1998 Eclipse has the 420a non turbo Chrysler engine in it. All the service manuals and how-tos I find talk about the fuel filter being on the firewall and the fule pump being able to be accessed under the rear seat. This is not the case on my car. The access under the seat has no fuel lines going into it. Just a wiring harness for the float.

Crawling under the car reveals what appears to be the fuel pump and some other "canisters" under the tank near the frame. Where can I find information on this setup? Is it factory? If so what all is down there and what are the part numbers? Info on this setup seems to be quite lacking and I am wondering why.

What prompted me looking into all this is the car will start just fine, will rev up for the most part. However, going down the road the car will die within a minute or so. It won't start for at least a minute. During that time if I crank it over it will not start. It does not generate any error codes to a scanner and the check engine light does not come on.
