I just put on a NAPA spin fuel filter on my stock M37. It seems to be doing the job it was designed for. However, it seems to me that I am not getting enought fuel up to the carb. The fuel pump that I have the truck is less that 3 years old and I have never had any problem with it before.
You may lose a couple of psi of pressure across the new filter....
My son replaced the mechanical fuel pump with an electric one in his M37 after the pump leaked gas into the crankcase, so it can certainly be done.

Most pumps, especially the electrics, like to push better than pull. An electric, mounted close to the tank is my recommendation.
I was sold on them the first time I ran out of gas and didn't end up running the battery down trying to get fuel up to the carb; just turned on the power and when the electric pump's rate slowed down it fired it right off and I was on my way again.
If you do go with an electric pump (I'd check first to see if that new filter was clogged...) make sure that you get a low pressure model or instal a regulator. It's real easy to get too much pump and then flood out the carb... I think that you are looking for 4-5psi, but I will verify.
