I have a 1998 Isuzu trooper that I had to replace the fuel pump assembly and when I removed the assembly I had to cut the bolts. I need to know the size bolt to attach the fuel pump assembly to the gas tank. there is 8 bolts I do believe. It goes thru the assembly and thru the seal then into the tank.

 

Ive got a 2000 trooper that I dropped the tank on. I can look at it tonight and let you know. I'm looking for someone who sells replacement tanks for Troopers???
