i have a 1991 R2500 suburban, the repair manual does not break the circuit board down. there is a part on this board that has a heat sink attached to it,unfortunate foe me this (what ever it is) is overheating and breaking open and spilling its guts. at some point after running the engine it shuts the fuel pump off. after sitting overnight when things cool down the fuel pump is allowed to run (for what ever time).if the circuit board is pulled the pump is allowed to run as normal (so far with not a lot of time driving). I'm trying to locate this non existent part or the component to fix the circuit board. the part number stamped on the housing for the board is #10052955 , any help out there. thanks

Interesting I found information that the module was replaced with OEM part number:
10052973
U.S. market on July 1, 2010

Does the connection fit?

When parts are superseded, they are improved. The board is probably upgraded so the soldered points don't break. The '90 trucks had problems with their wiper boards. A good mechanic could fix his own board. Or an upgrade was installed. Post pics once you have them taken apart.

the problem i have is with one of the components that is swelling and the material is oozing out. its hard to read the numbers on the component to be able to find it at the local electronic warehouse. the number is the key.

after i googled the number on the back of the circuit board #p9126-3 , then going to the site (67-72 chevytrucks.com) old posts from 2004 to 2010 pooped up with the info that i may need (post #6). the part in question is a voltage regulator.the post was talking about earlier model years but may have made some changes by the time it made it to my 91.hope this info may help others in the future. thanks for every ones help.
