Anyone know the bolt size for the tank straps? I gotta change out my fuel pump and I will most likley break every bolt trying to get them off. I just wanna have some replacments ready.

Tank strap Bolt is GM #11508133
M12 X 1.75 X 30 10.9

Tank Strap nut is GM #11509156
12 X 1.75 X 10.5 10M


Just use some PB Blaster or other penetrating oil and they will be fine to re use.

For the fuel pump swap make sure you remove the pulsator and you may want to replace the rubber oring and metal locking ring.

Sending unit O ring GM #22515965 *Walbro pump should include one
Metal Locking ring GM #22516548

Thanks Jas. I got the lock ring and the O ring was included in the kit. And I will be sure to remove the pulsator, had that in the plans already. I have been putting penetrating oil on them each day now. I just have a history of breaking bolts on this truck so I figured I would pick up some just in case. Thanks!
