I was looking at a fuel plate on ebay they say its #6 or #11 depending on the year of the truck I though a #6 was always a 6 and #11 always an 11 and you use different plates to get a certain amount of HP depending on the year of the truck and which tranny you have!! If you want to look on ebay its #794550465. How do you tell which plate this is?

 

I guess no buddy has the answer

 

I guess he is talkin about which pump you have 160,175,180,or 215.

Like a #11 plate in a 215 pump may make as much HP as a #6 plate in a 160 pump.

 

I could not figure out the profile on the smaller (hp) plate. Definitely some custom grind that doesn't resemble any plate I've seen. Maybe it was the poor photo.

The larger (hp) plate appears to be a #4 knock off.

 

thanks for the replys a fuel plate has differnt effect on differnt trucks (pumps) but the plate only is one # right?

 

That is correct..

 

Are the pumps that differnt? I see on tst 's chart for which plate to use that they have differnt size injector in the trucks with varing HP so is it the injectors or the pumps?
