Potential Fuel Pressure Regulator Solution
Looking into potential alternatives to our NLA fuel pressure regulators.
Here are some photos of tansplanting a later style Delphi regulator to the original LT5 regulator body. So far looking very promising. Next step is machining a retainer ring and drilling and threading several screw holes to hold it together. Then test it out. Will keep everyone here posted as to the results.

Re: Potential Fuel Pressure Regulator Solution
Is the stock one just a press fit?

Re: Potential Fuel Pressure Regulator Solution
The stock one is an old school design with a separate diaphragm and valve disk assembly under the vacuum dome.

Re: Potential Fuel Pressure Regulator Solution
The L98 was a bolt in top.. maybe a ring with screws to bolt in..

Re: Potential Fuel Pressure Regulator Solution
Retainer ring finished and regulator installed on the fuel rails. Now on to the testing phase. Wish me luck.
