anyone know what size the bolts are that mount the pump to the intake manifold. i had them and now cant find them and spent hours searching the web but can only find all other bolts but those.

im in the midst of doing the 99 intake swap with the newer style bracket and pump.

 

What year? I have a renix will that be the same? I have the pump and bracket off so it will be easy to measure, but let me know if it's the same first.

 

i dont believer theyer the same its to my understanding that in 96 they changed the bracket and such

 

The three bolts to mount the pump to a '99 manifold are M8x1.25x95mm.

They have a captive washer on them but I think that a flange head bolt will work.

I doubt you can find a 95 MM length bolt at the hardware but a 90 MM length may work; the extra 5 MM is the threadless pilot on the threaded end of the bolt. Even 90 MM will be hard to find. You can check with Fastenal to see if they have them (flange head). The longest M8x1.25 bolts I've seen at a hardware were 80 MM long.

OEM part number is 6502425. MSRP $5.45.

 

great info. thanks for this.

 

Went out and checked my bolts. It looks as though you could sneak an 80 MM length bolt in there (with a washer under the bolt head or a flange head bolt), but the threads would not protude out of the manifold.

If you get bolts from the hardware make sure that they are at least Class 8.8 bolts.

 

that's good to know cause the nearest dealer isn't exactly close so hopefully i can find them at a hardware store
thanks CCKen for all the help and info

 

7/16-14 work perfectly.

 

Agree, can be found at Tractor Supply

 

I think the OP is talking about the three bolts that hold the pump to the '99 intake manifold (which are M8), not the mount bracket to the water pump.

 

Oh snap!

I'm so used to seeing posts about busted/rusted/AWOL steering gear-box bolts....
"Pay no attention to the man with the loose nuts behind the steering wheel."

 

I could use the measurements for a renix. My Comanche is an 89 and I don't have any there. Been looking forever for someone who knows the bolt specs.
