I guess that old saying “you get what you pay for” is accurate for fuel pressure regulators as well. After having trouble with the Holley regulator, I did some research and read reviews on different manufacturers and landed on Fuelab. They seem like a specialty manufacturer of fuel pumps and regulators that know what they are doing.

While investigating the fuel system to try and address the rough running issue, I noticed that the fuel pressure in the rail would drop off quickly.

I removed the throttle stand assembly and decided to have it bead blasted at the same time as the intake manifolds.
I am finally to the point of installing the new fuel rail. I started with a rail from an HE XJ-S. It was well worn when it arrived so I cleaned it up and sent it off to get zinc oxide plated in the original color.
In 2004 (10k miles ago), I removed all the injectors and sent them in for an ultrasonic cleaning and assessment to The Injector Perfector. After servicing them, he painted them gold (?) and replaced the fuel hose on each. I have read that these early Bosch injectors are pretty reliable, but with all the effort I am going through to improve the fuel system, it made sense to have them checked again.
My main goals for the fuel rail project are to keep the fuel hoses as short and straight as possible and to de-clutter the engine bay. With those goals in mind I decided to relocate the fuel filter to the trunk.
I have started the project to fix the vapor lock problem.
Shortly after purchasing the car I logged the following comment “After engine is warm, rough idle and hesitation on acceleration”. Over the last 20 years, this has been the most consistent annoyance. The following has been done to try and address it: Continue reading “Runs Rough”
