This is a Sierra mechanical fuel pump, part number 18-8860, built to replace the pumps fitted to GM based V8 engines of 454 and 502 cubic inch displacement. It also replaces MerCruiser 861677T and 818383T part numbers. Output is 6-8 PSI, and the maker says it meets manufacturer specifications for approved applications. A mounting gasket comes with it, so you do not need to source one separately.
Our take
The 6-8 PSI output is the figure to check against your engine's spec, since this mechanical pump replaces the one on GM based 454 and 502 V8s. The included mounting gasket means one less part to find when you pull the old pump.
