Fuel Line: Unfortunately that 5/16" rubber line with a rusty hose clamp will not live up to the pressure requirements of your new electric pump. For all standard applications, it is recommended to use a 3/8" fuel injection approved hose for your supply and return plumbing. In lower horsepower applications a 5/16" supply line can be utilized but it is vital to take multiple pressure readings to ensure consistency. Our Sniper EFI Master Kits are supplied with 20 feet of EFI compatible rubber hose. here

Fuel Filters: Most carbureted applications will require a 100 micron pre-filter (before fuel pump) and a 40 micron post-filter (after pump, before carb). A Sniper EFI system requires the use of 100 micron pre-filter and 10 micron post-filter. I t is critical to use high pressure clamps or AN fittings to reduce the possibility of a fuel leak. here

Fuel Pump: On average, your block mounted mechanical pump will produce up to 10 psi of pressure. While it can move the required volume of fuel, it cannot maintain a pressure needed to supply your Sniper's fuel injectors. Alright, but what electric fuel pump should I use? We have three options when it comes to high pressure pumps: here

Okay, great! We've found a Sniper TBI system that will bolt onto your existing intake, but what else is required? For starters, your fuel system will need to be upgraded. Holley carburetors operate at a range of 5.5 to 7.5 psi of fuel pressure and use a 40 micron filter. Sniper EFI throttle bodies require 58-60 psi of fuel pressure and a 10 micron filter. Let's take a look at the items that would need to changed or can handle the higher pressure. more

So you're ready to switch from carburetor to fuel injection, but you're unsure of what all is involved. This guide will walk you through a basic installation including what parts are necessary to swap as well as what to watch out for. It's time to move towards better fuel economy, increased performance and perfect cold starts. Let's get started!

I looked into doing the EFI swap and adding the vortec heads to my 5.7 TBI. I ended up getting a new moter instead. Sounds like it certainly can be done relatively pain free.

But I do have some spare parts that may be handy for you, I’m guessing most of the parts are interchangeable between the 5.7 and 5.0

Off the top of my head I believe I got these,
Tested and working alternator
Ignition coil, brand new
TPS sensor
MAPP sensor
IAC valve
Serpentine belt.
Water pump.
I’m sure some more stuff as well

Teething problems aside, I�d agree the Sniper runs much better with timing control. It fixed my inconsistent starting problems that I was trying to tune around for a year.

[TaiGel]

My theory is that since my 6AL was getting the RPM signal first and sending it to the Sniper, that it'd run on the prime shot and/or residual fuel vapor before the Sniper had an RPM signal. With timing control, the Sniper gets the RPM signal first. I noticed this immediately when converting over. There�s always a longer crank present before it starts, but it starts way more consistently. And no more weird heat soak related starting issues.
