hi all i want to go from bog stanard pinto with points ignition etc
i already have a fr32 cam/ omex 600 and a manifold with R1tb's inc tps waiting to go in the question is what else do i need? ive been told i need
Small filter into a
low pressure lift pump into a
Swirl pot into a
High pressure pump into a
High pressure filter into the fuel rail then out into a
High pressure regulator
is this a load of bull ?
or can i just supply the fuel with a bike fuel pump
so im after finding the way to fuel it and any other bits and bobs i need to know to make it run.
thanks

The low pressure and swirl pot side is to provide resilience against fuel starvation on corners.

I would indulge in some porting and valve work on the cylinder head otherwise you won't see the potential of the cam and the fuel injection.

the tb's require fuel at about 50psi (give or take)
Bike carb pump will be at about 2psi.

A bike injection pump may do the business though.
However, you do need a swirl pot somewhere. Can be inside the tank, or use a combined in-tanl pump/swirlpot, or as described an external swirlpot with a lifter pump as well.
So what you have been told is indeed one way of doing the job, probably the simplist too. which is why I am using an intank golf pump/swirlpot, just to be difficult!

I am using one off a mk4 golk.

Never looked at the earlier ones, but "should" work. Worth checking, the golf tank may have had an internal swirl pot as well??

as im as thick as 2 very short planks
how do you get the internal pump swirl pot etc in your own tank and make it leak proof

My understanding is that you dont actually have a "swirl pot" in the tank. What you have is a Sump, which is usually accompanied by a baffle or two. The Sump I guess keeps a buffer or reserve of fuel, which the supplies the engine under heavy demand. The baffles stop the fuel slurping around and assist with the Sump getting the required amount of fuel "fall" into it.


I have been told that this setup is actually better than a seperate Swirl pot setup ( although that could just be one persons opinion ) . I think I will be going for this method as it does away with a low pressure pump and reduces a little complexity for the fuel run.

Ah, my cunning plan involve a mate with access to a steam cleaner (clean the tank out) and a variety of metalworking tools. He is cutting a suitable plate to accept the pump, and will either braze or solder it to the top of the tank. The pump will drop in, and be held down by some little screws and sealed with a mahooosive o-ring or a gasket, whatever he can acquire off a fork lift truck
