Title: Connecting IP fuel hoses
Post by: haybayian on February 21, 2008, 05:34:51 am
Could someone help me connect fuel lines to my injection pump. This engine is totally new to me and I am in the learning mode.

What I see on my pump is:
1)close to the sprocket pulley there is a banjo fitting . What goes in there?
2) on top of the pump another banjo fitting with a small barbed connector attached to it, (is this a return from the injectors?)
3) underneath (2) there is a rubber fitting (about 1/8") maybe vacuum. What does it connect to ?
4) under (3) there is another banjo fitting with a # 1/8" ID pipe at one end and a barbed connector on the other side. Is this the feed port? Why two openings?

I would be grateful for your help and, if you have one handy, a picture of your pump.

Thanks.

I'm thinking you should post a pic of your pump.
Sounds like you have a non TD pump?

Your year & make and turbo/non-turbo would usually help.

1.  Fuel supply coming from filter

2. Vacuum line to manifold (boost fuelling)

3.  Vent.  Nothing connects there

4.  Fuel return line (back to tank)  Small barbed connector is return line from injectors

A is the return line to the tank going to number 4

Here you go. This pump has always been refered to as coming from a 1.9 TD. If this is something else I would be glad to know.

Thank you very much for your elaborate answer. My pump comes from a 1993-1996?  1.9 turbo Jetta.

Looks like CoolAirVw's post should answer your question no?
