Default How many pounds? 90 L98 fuel injectors.

Just to find out ahead of time. How many pounds of pressure/hr. does stock 1990 L98 fuel injectors produce. If I need to replace them inwhich I may have to from a earlier question I had on the Forum, i want to keep my eyes open. I just saw a new set of eight accel 30 pounds going off shortly on ebay fairly cheap. Thanks vettefast :chevy

They are 22lb/hr full flow at 44spi.

A set of 30lb/hr injectors would be way too much for even a lightly modded L98.

You can use the 24's, you just need to buy an adjustable pressure regulator and turn it down some to help the ECM compensate.

That is exactly what I did about a month ago. Car now runs fine. However, with the new injectors my average mileage dropped by about 4 mpg......... :skep:

I looked up " 5 0 motorsports" and it did not come up on the web. Is there a web site or a different name I can look up? Thanks! :nonod: Vettefast

I just found ford svt racing 24#lb/hr in Summit for $219.95. A friend of
mine used them in his supercharged 86 with the regulator and he says they work great. :auto:

When you get them installed let us know how it works out! If it runs great or to rich or if there are any adjustments you had to make to make it run better! Thanks! :cheers: Vettefast
