Fuel Injection-What modifications needed

[Blitzkrieg]

I have decided to use fuel injection, instead of carburretors

Now, what modifications are needed with regards to the fuel lines?

I know that there is the one standard fuel line running through the chassis, can that stay or does it have to go?

I suppose that it would be easier to modify the fuel lines on the new chassis now, rather than doing later when the body is on...

Help would be appreciated

This is what I'm doing/ going to do. Back to front.

High Pressure fuel filter mounted on the firewall, properly mounted with brackets, replace all fuel lines front to back with new hardlines and fittings, running under the pan, attached to the pan running two cause one will be the return line from the fuel rails. Either High Pressue fuel pump mounted in front if I can get a nice quiet one, or a submersed one for that stealth look. Modded tank upfront so that a return line can be fitted

Could I still use the standard hard line that runs in the tunnel and just fit one next to it for the return line?The ones in my chassis' are still good so I might as well use those...

I'm planning on using a Golf fuel pump, around R500-00 for a new one...

You can use the standard lines, but they've been running through that center channel for MANY a year, plus I'd prefer fitting slightly larger diameter lines than the stock set-ups, I bought 10 meters of nice pipe from a place in silverton for about R150-00.

Shop around, I saw the golf units for R320-00 at golfwagen.

These fuel line that you have bought, are they metal lines or rubber pipe?

The problem with fuel pumps is that you get differing qualities...

I would like an OEM Bosch pump, but they are rather expensive...

I believe that IMPI used a pump from a Colt bakkie...

The lines that are going to run under the car are metal lines. They'll be attached with the same hardware that Honda uses on the civic, it looks neat and mounts to the floorpan of the car.

I think that you can mount up to three lines next to each other, I'll only be needing two.

I'll probably use a Honda Civic pump as it's small, compact and will fit inside the tank, plus R430-00 is a bit of a bargain.

Downside is that it'll fit on the top like a fuel sender unit, so you'll see the pipes under the hood.

Sweet, thanks Gary

I'm pulling out the old pipe from the tunnel today, will most likely go pipe shopping this weekend

Would like to run all fuel lines through the tunnel, to keep it clean and stockish

[flatfourfan]

main reason I decided against the tunnel was that the lines have to be attached to something and VW tacked them in the tunnel, bit of a cow to do that without cutting the tunnel open.

[Blitzkrieg]

Damn!!Didn't think of that!!

Is it safe to run the lines underneath?

[flatfourfan]

lol, pretty much all car companies do it nowadays.

Okay then...

I will have to source the fuel line this weekend..
