This week I have been upgrading one of my daily drivers and removed the stock engine with a built 4.1 which will be converted to e-85.
A while back I installed one of our custom billet fuel sender using the stock lines and the fuel pressure was set about 45-50 PSI.
The fittings on the fuel sender were changed this week to -8 supply and -6 return, and the appropriate braided lines were used.
The -8 supply line was connected to the stock fuel rail using one of our new adapter fittings, and the internal opening of the connection fittings are double the stock line.
The return line was connected to a Kirban regulator in the stock location with a custom made adapter for the -6 fitting also with a larger internal opening.
I was astonished when the pressure gauge was at 75 psi which was easily dialed down to the original figure!
The stock lines have a serious handicap with line crimps and fitting GM used. The stock fuel rail is more than adequate for LOTS of fuel supply as we have modified the inlet on the stock rails for years by welding on AN fittings.
We now have a simple and easy bolt-on method to increase fuel supply to the engine.
I am a simple person and think that way, so I ran the supply line on the pass side and up along the back of the valve cover.
The return line is on the driver side and also runs up to the rear of the VC to the regulator.
My flip phone does not take pictures, I need to wait for one of my friends help before I can post them!
