On board primer
« on: February 01, 2014, 10:30:12 AM »
Just added an on board primer system.  Small tank plumbed to an electric fuel pump with the line plumbed into the distribution block. We run alcohol, I was thinking of priming with gas to keep from washing down a cylinder, does this sound ok?  How do you guys do it?  I was thinking maybe a 3 count or 5 count then hit the starter. Or should they be operated at the same time?  336SBC, single butterfly, N/A.   Any Advice?

I added a primer system this past summer and after working the bugs out of the system it works very nicely (also alcohol).

I plumbed it so that the return line keeps the primer tank full so after the first start of the day I never have to add to the primer tank



I did have to upgrade the pump as the original could not over come the check valve at the distribution block

This link takes you to my web site where I talk about it a little, and I did not update it after the upgrades were made.

Scott I use the same pump as Glen but I prime mine with gas . I use a 1 quart fuel tank from JAZ and a single nozzle in the center of my tunnel ram manifold . I use a push button switch and give it a couple of shots when I am starting mine . A really good idea for an injected car you can throw away that squirt can !

Bill, my pump looks just like that, solid state Purolator.   Any special reason you went into the intake instead of the dist. block?

If your plumbed into the distribution block any alcohol in the block and lines will be your prime before any gas makes it there. It really doesn't mater which you use. Gas will help on those cold spring and fall days when temps are 50 or below. I found with mine I would prime for a second or two. Start engine and had to hit it a little more until all the lines filled.

I had to pull that pump and bought one from Spud. The pump in the picture just could not over power the check valve

If you are plumped into the intake you have to be very careful that the vacuum does not pull all the fuel in the tank into the intake. That is how I had mine set up originally, and I sucked half a fuel tank into the intake, contaminated the oil.

    I just looked at mine and Glen is right about it sucking fuel from vacume . I think that's why my pump has this little solenoid

BK, I thought about the fuel in the lines,  I didn't know how much alcohol would eat on the pump.  I'm going to give it a shot, I guess we'll know come spring.

 Most pumps now seem to be tolerant of alcohol. Did you use the Enderle primer fitting at the distribution block?

Yes, I used the Enderle  check.  I think they are set at 4psi.
