Universal electric pump for priming.

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.

Greg,

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
