Question:

Since the entire fuel system for a GSL-SE is set up for high pressure fuel injection, is there anything needed to change if I want to eliminate my EFI and go carburated? I assume I'd at least need to tone down the fuel pressure from the pump.

I've remember reading about someone that was trying to retrofit EFI to a carburated 1st Gen who indicated the gas tank needs to be switch'd. Something about baffels.

Inpute, experienced thoughts, learned opinions????

 

a fuel pressure regulator is a cheap mod that'll help regulate fuel flow to the carb. a carter fuel pump (rated @ 9.5 psi i believe) wouldn't hurt either so as to take off excess pressure on the FPR

 

I have done this. You do not need ot change the tank or the pump, You just need a mallory return style pressure regualtor. Works perfectly

 

So, in the alternative, if I replace the fuel pump stock type I'm good to go carburated?

 

You don't need to replace the pump. You only need a new return style regulator.

 

sitting in my garage. So no additional cost if that is good enough.

Good enough?

 

correct, either way wether you get another pump or not you NEED a pressure regulator or else you will just Pwn your floats.

 

Yeah, what FBII says is true.

With any aftermarket fuel pump you need an FPR to go carbed. I've got a Mallory Comp 70 6psi/70gph fuel pump and I needed to buy a Holley low pressure FPR to bring the pressure down to a managable level. The difference is that with the 6psi pump, a non-return style FPR works but with the higher pressure EFI fuel pump you *have* to have a return style one.

So since you have the lower pressure fuel pump, go out and buy a 1-4 psi FPR and regulate your fuel pressure down to about 2-3psi for any stock or modded nikki. IIRC a Holley can take higher pressures.. Dunno about Weber and Dellorto. What carb are you planning to run?

is to go Mikuni. I've tried Holly, Webber side draft, and Mikuni. Not as deep as what a Holly gives, but faster reacting to the throttle without the extra noise of the Webber.

 

but but.... weber = teh faster! do i have to post pics??

 

go with a sterling carb

 

You can use the stock SE pump. For the regulator, use a mallory regulator OR the EL CHEAPO holley but with modified outlet to allow installation of the f/p gauge and the return line.

 

YES YES YES YES!!!!!!!!!!!!!!
