RE: Is this the correct Fuel Pump for a 914-6, F.I. pump on Ebay says its stock for -6 Options

[Dominic]

After looking at this auction, I noticed that the pump he is selling is the stock Fuel pump on all VW type 3, type 4 and 914-4's with F.I. He claims it will work on carbed 911's and 914-6 ?

I looked it up in the book of knowledge (Factory Parts Catalog) and it gives me two seperate part numbers:

For the 914-6.... 911.608.107.00 translates to Bosch part# 61309 (Bosch# 0 580 960 009)

For the 914-4..... 311.906.091 D translates to Bosch part # 61305 (Bosch # 0 580 463 005)

I didn't think that the carbs could work with this type of fuel pressure unless it's regulated to 5 psi ???? (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

This story will likely create some debate, but...........
A car I once owned came to me with Webers and the stock 4 cyl FI pump. The pressure was regulated by a hose clamp on the line from the stock Djet pump, then the fuel entered a block with a guage and 2 lines out to each carb. If you look closely you can see the clamp in the picture below. It was a system provided by PMO (they do know carbs!). I couldn't believe it was safe after reading posts like those above (roasting marshmellows, etc) so I called PMO. I was told not to worry. The 30+ lbs of pressure in the FI fuel ring is created by the stock fuel pressure regulator. Remove the regulator and it is like removing your thumb from the end of a garden hose, pressure goes down. I used the system for the three years I owned the car with no problem. In fact I never loosened or tightened the hose clamp "regulator" because the gauge showed about 3 lbs and the carbs performed well.
