2.3 turbo fuel pump issues...

ok so i have swapped a 2.3 turbo from an 88 turbo coupe to my 86 ranger...keeping it all stock for now for simplicity...i bought a fuel pump that was supposed to be rated at 85psi max...turns out its rated at 125 psi max...so stupid me i bought a regulator for it and it just irritated me so much not working right and what not, so what i am wondering is what exactly is the psi that the stock pump pushes?...and where can i find an aftermarket inline fuel pump of that psi rating?..

i dont want to put one in the tank because of the different plugs and floats used i think it would be a hassle compared to just puttin in an inline pump with the stock fuel rail mounted regulator...

I'm not sure of the exact rating of the stock pump, but if you're running a carb instead of EFI (I assume so because of the reference to floats in your post) you only want about 5-7 PSI max. 85 and 125 psi are way high for a carbed engine, and even a bit high for a stock street-driven EFI engine. The important figure here is the GPM rating, of which I would guess you'd be good with about 70 GPM. This is easily doable with an aftermarket inline pump, but the good ones aren't cheap. Take a look at someplace like Summit for a good variety of pumps and their specifications.

Ah ha...now it's slightly less clear than mud! Anyways, EFI is still in the range of 35-45 PSI stock so your 85 and 125 PSI figures are still higher than needed. I take it then that your Ranger was originally carbed, so there is no stock in-tank pump?

you got it....i drilled and hole and added in a return line to the top of the tank but i wasnt sure if the stock pump pushed 45psi ...or something smaller or bigger....so i figured there was a good deal on an 85psi inline pump and thought the regulator would be able to tone it down, but i was wrong...so before i spend some big bucks on another pump...i found a 55psi pump for about 150 bucks...a 45 psi pump i found was like 200+ ...seems the closer ya go in that 35-45 psi range the more money they want...

would the 55psi pump work?...or still be too much?

I would think the 55 PSI would work and that your regulator could handle it better. But I'd hate to see you drop 150 bucks on it and we find out I was wrong...

Another thought occurs to me: there were some inline pumps on earlier FI Fords, they used a two-pump system with the inline pump being high pressure and the in-tank pump being a low pressure booster pump. If you scrounged one of those inline pumps from a boneyard, like off an F-series truck with a V8 it might put out enough by itself to run that turbo motor for a whole lot less money. Might be worth doing a little online research to see just what those pumps did put out.

Did your truck have a 2.0 engine in the 86 as you said you had to add a return line. The stock Ranger pump will deliver enough fuel, but most change to the Walbro 225gph pump.
