240A first start and prime?

[1985 CCX]

Anyone know how to get the prime started in the 240A?
It turns on and pumps but it is dry at the moment, do not want to burn out motor trying to get it wet.
Have it feeding the mechanical, should I just start the car and let the draw off the mechanical Carter pump?

Running 289 tank to 240A then to mechanical in front through regulator and into 4IDA..............

Thanks

Hey Jeff,
I removed my pumps early this spring, did some work to them and re-installed. They wouldn't prime! That was a first.

I have a mechanical pump at the engine. I then cranked and fired the engine for a few seconds. Shut the engine down, flipped the pump switches and low and behold.....the 240A's were primed and ready.

Since then, when I hop in for a drive and before I start the engine, I'll check the 240A's to see if they're still primed. They always are.

Let me know if you have the same success.

The mechanical pump should pull through the electric, this is how SAI originally installed them and I did mine the same way.

Thanks guys!

Will give it a shot this week.

Electric pumps don't prime easily unless they are gravity fed.

Mechanical pumps "suck" better than electric.

Electric push better than pull.

Great

I will start with the mechanical Carter and then turn on the 240A.
makes sense as it is diaphragm style I believe.

Many thanks
