Mechanical Hilborn fuel injection users
What system/method do you use to prime the injectors on start up?

I use a small tank built into a stand that sits on top of the Hilborn units stacks. It gravity feeds a barrel valve, feeding 8 individual lines, that drip into each individual stack. I can adjust the flow with a shut off petcock. Like the sprint car guys use, or when I don't have it handy, a Zep spray bottle.
I was asking how other people did it.
Have you set up a Hilborn stack unit on a hemi engine using the low mounted pump/non cam driven pump you mentioned? Who makes the pump mounting system?

On my plymouth I've got the pump mounted in the olny place it would fit, with a belt drive. It'll start on it's own, but if its been sitting I prime it with a squirt bottle for quick startups. Anything under a few hours and it fires right up. I would have mounted the pump off the cam, but I had to have a water pump. David

You can get the pump adapters direct from Hilborn as they still make them. I also see them on Ebay pretty frequently.
We use a squirt bottle - once the motor's been fired it later starts pretty easily. We keep a squirt bottle handy - just in case. I thought about making a manual priming system - nothing fancy - cable operated to keep things simple. Others I have seen use a small electric fuel pump with a momentary switch.

Yep, I've got a nice 331 ch 8d (331 354 392) Hilborn injection for sale on E bay right now. Last day.

Re: Mechanical Hilborn fuel injection users
I read someone's post elsewhere 5 years ago about using a small propane tank and push-button solenoid on the start cart, quick-disconnect single hose to a fitting on the chassis near the engine, and steel brake lines leading from there to small fittings in the side of each stack (above the throttle body), no picture shown but sounded good. Solenoid is powered off the cart so no battery needed in the car. IIRC he said he didn't want the propane on board (alcohol car) lest he be accused of hiding nitrous!!
Downside: solenoid failure is a potential fire haz, but can't hurt the engine if the throttles are closed. Crew has to remember to disconnect!!
No liquid leaks, can't flood, no plug fouling.
The brake lines are Adel-clipped to the frame and injector casting, so no loose hoses.
