[QUOTE="TARM, post: 446719, member: 578"] That is a fav but just an FYI to everyone: I called Bosch for other reasons a while back and I was told they are no longer producing the Ford 7.3 fuel pumps as of this second or third quarter of this year . Any pumps going forward will be Carter or airtex. So once stocks are depleted off the shelves it will be salvage yard only to get them. Maybe someone else would be willing to call as well and confirm this. If correct I would get them while there may still be some on the shelves. I can tell you from looking at the specs of the other pumps the Bosch's are for a number of reasons a much better made pump. Flow rate is only a small part when you are talking about durability. The dual pump is the reason I find the Holley offering so appealing. Two pumps that can be wired to work just like our dual setups but they coming in all one housing with a single 10an inlet/outlet. This saves on extra fittings etc. You can wire it a number of ways. One run full time and the second to only come on where either a min pressure is reached or via boost, throttle position I would think could be done as well. With these you would run two separate 30amp relays for each pump. If you just want it to run like the typical dual stock pump running together full time then a single 40 amp relay with both power leads combined into the one relay. The pump can also be submerged so I could build a surge tank to fit it as well. I think this pump would be the one I would use on the next fuel system I build. They are suppose to have a rated 100,000 mile regular driving duty life or 3000 hr continuous on duty life. I thought the pumps were brushless but I must have read it somewhere else as I can not find anything in any of the documentation. It would be nice but not a deal breaker as the bosch pumps use brushes and last for 200K and more at times. I very happy when I saw they were diesel rated as usually most pumps are not. [/QUOTE]
