Have some questions for a '84 GT 350 I'm currently building. I want to convert the car to fuel injection. Most likely be a 347 stroker engine to keep stock-like appearance.
Here's what I picked up so far:
-Stock gas tank for fuel injection
-Fuel pump cage assembly
-Walbro 190 lph fuel pump GCA710-2 Link- https://www.summitracing.com/parts/vpn-gca710-2
Here's where I think I'm going to have problems.
I want to keep the dual snorkel air cleaner so I picked out the Holley Sniper fuel injection kit. Link to kit - https://www.summitracing.com/parts/sne-550-511k
Reading through the instructions, it states that I need 50 gph (no problem with current pump), but I need 55-65 psi. Is this pump capable of this? I found only one pressure listing for this pump and it's rated for 45 psi normal operating pressure.
The next obstacle is the line size. Stock pressure fitting is 5/16" and return fitting is 1/4". Holley states a minimum of 3/8" feed and return line. They also state you should not have more than 3 psi in the return line or you may run into tuning problems.
Is there a way to adapt to that line from the tank fitting?
I'm feeling like this may be a dead end trying to keep the stock air cleaner and having a stock tank with in tank pump.
Anybody have any ideas?
Scrap all my ideas and start over?
I could go with factory injection, but would have to get the harness, computer, etc.... and it would not look right, and I'd loose the air cleaner I like so much.
ETA: Just thought of this too. I could add a sump to the tank I just bought and put a fitting of the correct size in it. Then, cut a disc to fill the stock pump hole and add a fitting to it for a return line. Does that sound better, or not?
