Holley Sniper EFI?

[78elk]

Has anyone put in the Holley Sniper EFI system?

I put one on a mild 350 in my old S10 Blazer. Worked pretty good. I'd do it again.

Thank you. What fuel pump did you use?

 

[Chevellefan]

I used a Walbro 255 in-tank pump. It was in an S10 Blazer, so I was able to get a new tank + sending unit cheap on ebay. I just put the better pump on the sending unit.

here's where I wrote it up.. 1985 V8-S10 Blazer - Page 12 - TireSmoke.org

been running EFI for a long time.. happy to help if i can.

Thank you. I'm going to try and use the tank I have. It's a spectra tank made to fit the El Camino. I put it in new in 2007. It doesn't have many miles on it, so I'm going to try it. I'll share what's going on with it and if you can help me that will be much appreciated.

With fuel injection, you really need a baffled tank to prevent cavitation. You would need an El Camino/Caballero tank for the injected 4.3 V6.

Thank you. I wasn't aware of that. Much appreciated.

Will a Holley Hydramat work in place of the baffles?

It looks like a good solution for your stock tank.

Thank you, I'll give it a try and maybe have to change the tank.
