1998 502 MPI MEFI-3 parts: Two of everything.

Upper and lower intake manifolds.
MEFI-3 ECMs, untouched.
Throttle bodies.
ECM and injector wire harnesses.
Cool fuel pumps with fuel lines (no covers).
Fuel rails for short-style MEFI-3 injectors.
Injector sets (brand new from BUP in spring of 2019 - maybe 15 hours of run time if that?)
Circuit breaker/Mercathode bracket (just the bracket).

No distributors, coils, knock sensors..

Parts will need to be cleaned for installation. Were used in brackish and salt water - intakes are in good shape - cool fuel pump brackets will need a little attention. These came off of engines that were last run a month ago or so. I'd prefer to sell as complete sets but may consider parting out if no takers.

$1200 each plus shipping. I'd prefer local pickup if possible (the manifolds are heavy).

I will get some pics added later.

Thanks!

What are ya changing to?

AFR 325s, Crane 621 cams, Merlin intakes, Demon 850s, Hoping to add some good umph to the old 311.

Pics...

Fuel pump assembly and wiring still on starboard engine as well as ECM. But they’re all the same. Mounting bolts etc are all there. Thanks for looking.

They look good, won't take much clean up to plug and go to anyone with a stock 502
Make someone a great upgrade

The rail and injectors are different then mine, there older then yours

I’ll have camshafts and roller lifters, pushrods, etc too. All in great shape. Whole package.

I’m going in the same direction. I’m selling 2 excellent condition complete 500efi systems. I’m building twin 509’s with AED 850 carbs, single plane manifold and crane’s 741 cam that’s equivalent the Mercury’s 525 cam.

What heads?

I’m just selling the fuel injection system off both engines and using the block and all the good mercury racing internals for the 509 build.
