My '54 will have a 5.0 Coyote - can I just use one of the cross member gas tanks that mid-fifty sells and buy a coyote-compatible fuel pump or does it have to be in-the-tank pump?

 

The in tank pump is the most efficient, in term of both function and space. But there are several applications that use an external high pressure FI pump. There's a Camaro/Firebird application that's popular with the street rod crowd exactly for your situation. I don't know the requirements of the Coyote system, but it might be a place to look for you.

 

In the tank is better but an outside the tank will work. It is better if the outside the tank pump is mounted as low as possible so the fuel will gravity feed after it is out of the tank. I am using an outside the tank pump with my Coyote but since I have a 52 and am using the stock bottom outlet tank I have gravity feed to the pump.

 

I have a 73 Mustang tank in the back of my truck behind the differential. I slightly bent the arms on a 1995 Mustang GT pump and it went right in the top. I put the fuel sending unit in the bottom hole. It still needs some adjustment, but gives me a fairly decent idea of when it's time to fill up. Since the 95 GT is a 5.0 as is the Coyote I suspect it would be up to the task and I'm pretty sure one could buy higher outputs. The only downside is there's no internal baffling in the tank(that I know of). I bought my tank from Mustangs Unlimited. If you go this route, you'll have to put the filler cap in the bed.

 

I opted for the 70 Mustang tank and still trying to decide on pump options. Subscribed.

 

I'm probably gonna go with a tank from Hot Rod City - they claim, I haven't called yet, to be able to set it all up with the proper pump for EFI engines and configured for a F100.

 

As for the 5.0 Coyote, an external pump should be able to be utilized. It havent done 5.0 research but as far as the 4.6s go, an external pump can supply adequate pressure. If you follow the install instructions you will be fine. As for mounting, low and as close to the tank as possible since the fuel helps cool the pump. Check out Aeromotive Inline pumps. Holley also makes pumps.

As for the 95 5.0 and new 5.0 pump comment.... they are completely different engines with 20 years of technology between the two. The stock pushrod 5.0 uses 19 lb/hr injectors. The new 5.0 Coyote uses 24 or 36 lb/hr if I remember correctly. That will require a different fuel volume supply and pressure more than likely.

If you call either company, Im sure they will at least point you to a part number and pressure/flow requirements. Its not the first Coyote to go into a non-coyote equipped car so there has to be a swap kit already available
