So, this project I picked up, 1988 2.6L 4x4, has a Mr. Gasket electric fuel pump wired in. What doesn't make sense to me, is why, when the stock mechanical pump as well as stock carb are still in place? IS this a common thing to do as a "lift" pump with the factory setup? Because to my understanding, the truck should run just fine without it.
I'm thinking that the electric pump was installed due to a problem of some sort, however the factory fuel pump has not been removed or disconnected.
All of my experience with cars is with port fuel injection, so carbs are a mystery to me.
Should I remove the electric pump and just run the mechanical one?
Can I remove the mechanical pump (prone to leaking fuel inside engine when failed) and use this pump? https://www.holley.com/products/fuel...s/parts/12-426
Can I use a self regulating pump with the factory carb? Or do they not like that and I would need to run a regulator anyway?
Last question: When Installing a Weber DGEV 34/36 later on, (Also, is this correct size for 2.6L?) can I simply run that fuel feed line out of the tank to the holley self regulating fuel pump, and eliminate the fuel return line? I couldn't find concrete info on this.
Sorry for all the questions but I'm still trying to wrap my head around carby engine things.
