Hard to start

[masracingtd1167]

Scott I use the Rons Primer plus with a single nozzle in the center of my tunnel ram manifold . I have it hooked up with a push button switch so I can push it a few times to keep the motor running if it starts to die out . I empty out my fuel system after a race so the first start up at the next race I have to prime it quite a bit to get the fuel lines full . After the car if warmed up it will only take a couple of like 1 second taps on the button to fire it .

I have mine plumbed into my distribution block, I hooked a fuel pressure to the primer line and my small electric pump is making 8psi.  On top of that I am running it through .028 nozzle jets.  Wondering if that's enough psi?   By the way, 336C.I. SBC.

are you priming with gas or alky ? If it is cold out it's harder to get alky to light ! My system is totally separate from my main fuel system and I use a small little 1 quart tank for gas

I have tried both, plan on using Alcohol, as that is what's in the lines anyway.  My set-up looks pretty much like the pic.

Do you guys start priming before you start cranking, or prime and crank at the same time?

Prime- spin- ign, at least thats how we do the blown cars

I had another thought, didn't hurt much,  I come out of my fuel tank, under/behind seat, into a 2" diameter 12" long stainless steel fuel filter, and then about a 16" long -10 line to my pump.  Could this fuel filter be making it harder to start? I have read some of you do not run a filter between tank and pump.

If you are priming your car it should start on that; yes quite a few of us do not run filters. I did run a filter between my tank and pump back when I was injected and had zero starting issues. with multiple connection points you could be getting an air leak which I think would just lean you out not make it hard to start.... maybe
