I think they are saying the same thing - that an in-line electric pump won't actually run the engine, but that if you select a "flow-through" in line pump, when it is off it will let the regular gear pump work properly and run the engine just fine.  The idea being that a flow through pump can be simply in-line and not have a bunch of valves.  sounds like a great idea!

I own a 1976 MCI8 with an 8v71. My mechanical fuel pump quit and I installed an electric pump off the shelf. There were two types, a low pressure and a "regular" pressure. (bought at an auto parts place) I put the pump inline at the tank. It's still there, I haven't fixed the mechanical pump yet. Bus runs like a dream.

In my opinion, put an electric pump inline, hook it to a toggle switch, it's there if you ever need it.


Life may not be the party we hoped for, but while we're here, we might as well dance.

Sounds very good.

Even better is to fix the mechanical pump and use the electric pump both as a backup and a primer  now that you know it works - peace of mind.

What size inlet and outlet tubes are on your pump and what is the brand & model?

Guys pressure is one thing they will run on 10 lbs but the pump needs to supply 65 gph at 50 lbs and above on a 8v to keep the injectors cool,I would repair the gear driven and do as Gus recommends me I always replace the old style DD pump with the newer DDEC pump 95 gph just my way because I don't like stuck injectors plus those little filters in each injector are a pain to change and they are going to plug without the correct flow and pressure.  

good luck
