Stovebolt.com Forums The Shop Area The HiPo Shop Holley Sniper install on a 235

Just finished the install of a Holley Sniper EFI on my 58, 3100, 235. This is my first experience installing an EFI system so I’m learning as I go.

I did have to get an adapter made to allow the TB to bolt up to the manifold.

After initial start up, the throttle blade had to be adjusted and it was ready to go. I also had to increase the start fuel percentage, which was done using the touch screen programmer.

Throttle response and starting have been improved. I’ve only driven it about 10 miles so far so I don’t have any fuel mileage numbers yet.

It’s been a fun project.

DB, you have an historic name, ever been in the northwest?

Ed

Once.

What did you do for the fuel system?

Removed the in cab tank and put a 15 gallon tank under the bed. I have a Holley in tank fuel pump. Ran steel lines from the tank to the engine compartment and incorporated a 10 micron filter in the pressure line. The tank is vented with a roll over valve.

Added a Fuel Link to get the 73-10 ohm tank sender to work with the fuel gauge. That still needs some fine tuning.

As long as you don’t mind having the tank in the cab, it would be a lot cheaper and easier to use the in cab tank. You could use an external pump and utilize the tank drain for a return.

I am planning to do fuel injection of some kind on my 58 too. I was looking at doing an underbody tank to get some space in the cab and move the noise of the pump out.

Do you have pics of your filler setup?

Fibonachu,

I wanted to keep the filler out of the box and I couldn’t find a place on the outside of the Fleetside box side that would work so I decided on utilizing the original filler location.

I bought fuel compatible hoses, one with 1” ID and the other 3/4” ID. That matches the fill and filler vent necks on the tank. I also bought a 76 Jeep filler and cap assembly, which fit nicely in the OEM style filler, rubber gasket. I ran the hoses thru the floor, along the outside of the frame rail and clamped them to bed cross sills. I neglected to get any pictures of the hose runs.

You are my hero. The original filler plumbed to the tank is exactly what I wanted to try and figure out how to set up.

Is the filler neck on the top or the side of that tank?

Here’s a better picture of the tank. The upper neck is for the vent, the lower neck is the fill.

What vendor did you get the fuel injection from and who made
Your adapter for the intake??
Very cool set up
