fuel pump in tank

[Vanity Plate Bob]

Why??

Simplifies plumbing and reduces assembly line time.

With well over 1,000,000 miles on vehicles with in tank pumps and no problems, I like them.

This is why we have a General Tech forum.

One of the reasons for the fuel pump in tank for fuel injection is to provide a reservoir of fuel under cornering acceleration and braking which is accomplished with baffles in the fuel tank or a "can" around the pump which serves the same purpose as the fuel bowls on a carb.
fuel injection is run at higher pressure then a carb sometimes as high as 45 lbs for EFI or TPI and requires different lines and clamps, filters etc and a return line (which can be normal low pressure stuff) to the tank.
There are other ways to provide for this reserve of fuel, but they require a additional "reservoir" and plumbing and a second fuel pump.
here is a view of a in tank pump install on a 72 tank for my TPI setup

it is basically a "can" with a partial slot to allow fuel in while the "can" keeps the pump inlet full of fuel at lower tank levels.
Hope I do not confuse anyone

On that subject, here's my set-up (note the fuel pump on the bottom of the surge tank):

Neet set-up with that setup you can run low pressure to the surge tank and only need short High pressure lines. Are you running an aftermarket fuel cell?

No fuel cell Craig, at least not yet.
