HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Fuel Injection Empty Fuel Injection

Post  epsylon9mm on Tue Jun 12, 2012 8:06 am

Thought I would share what I am doing/thinking with regards to fuel injection on my 928.

My 928 is a early K-Jet. I plan on running the factory Porsche fuel pump and fuel filter ( both were replaced recently before I started the swap ). The K-Jet pump should be good for about 70 PSI. I will be deleting the Porsche fuel accumulator which deals with keeping pressure in the lines while the car is off to prevent hot start issues with K-Jet. Once the Porsche pump fails I will go with something more economical.

Finding the right fittings to adapt the existing hard porsche supply/return fuel lines fitting to AN fittings turned out to be futile. For those that are looking to do this do not waste your time, I sure did. Ordering different expensive metric fittings from various venders online and waiting for them to be shipped only to find out they will not work. The best way to do this would be to cut off the flares, remove the fittings, and re-flare the hard lines for AN.

In frustration, I decided to carefully cut the crimped rubber fuel hoses off of the existing porsche barb fittings and reuse them on new rubber lines that will have AN barbed fittings to go to my fuel rail and pressure regulator. It is not ideal but it does work.

I am using an return style fuel rail setup with an adjustable fuel pressure regulator not the c5 fuel filter / regulator / return combo.

Fuel Injection Empty Lines

Post  ynbad on Sun Jul 29, 2012 4:14 pm

I pulled the fuel lines, p/s presure line and ac lines off, marked the way I wanted them pointing and took factory gm lines to a shop in town that makes up lines and they made the lines up with my fittings. I did the same with the oil filter they made up the lines as requested. All for less than $200.00

I bought metric to AN fittings from BAT in Florida; they worked fine for me but I'm still using a 928 engine, so I have AN-metric fittings on the fuel rails too. Can't you use AN lines for your engine?

I tried finding metric fittings that would work with the existing 928 fittings on the hard lines ( the convex or concave end would not mate up properly to create a good seal ). After trying a few 20+ dollar fittings I gave up. rpwach could you post information about the fittings you found that worked?

If I could have found metric/AN fittings I would have used nice braided lines to my fuel rails instead of the FI rated rubber hose I settled with to reuse the porsche fittings. This is something that I can easily do later with the right fittings hint hint...
