MPFI Spider
 

I have a '96 k1500 with a 5.7 R engine.
Spider assembly went bad,so ,try ing to save $$,I bought a set online,...yeah,...bad move.
So after 6 months they went bad....what brand do y'all recommend ?
Is Sorensen ok ?

Re: MPFI Spider
 

On fuel system parts I try to stay with Bosch, Delphi, AC Delco, Echlin..........any of the known brands that give good warranty.

Agreed Delphi or ac delco are my preferences. Get the updated injector assembly that converts it to multi point injection and ditches the single injector setup. I’ve had really good results using them in the past.

For example… the part in question on that list is the new GM assembly that has the injectors down on the bottom of the “spider legs” rather than one central injector and the poppet valves at the bottom of the legs that the original style injector had.
