Will this match my e4500 chev chassis that has 5 - 5 pin omron 13502750 2744a12 one is even for cranking the starter ?

It’s GM’s ubiquitous relay, I’ve installed them in s10’s 1/2 ton-1ton Trucks and vans, I would think they’re the same in their larger vehicles

can this relay be put in a chev expree 4500 rv?

You will need to get the Fuse Box diagram and see what specific relay is specified for that purposed spot in the fuse relay panel of your vehicle. Once you know the relay model specified, you can determine if the Omron 5-pin Black model 12077866 can be substituted. I do not know if it can be substituted.

Can this relay work for a 97 Tahoe fuel pump relay?

My '97 Cadillac DeVille uses a 4-pin relay for the fuel pump. The relay you are asking about is a 5-pin relay. Examine the relay in your vehicle first and see if it is a 4-pin or 5-pin relay.

Could this relay be used for a Silverado fog light relay?

Yes this relay could be used for this and other things, if it can run a horn or fuel pump it can run fog lites.
