What are the fuel pumps Cig used as stock on a 93 TG?
I can picture them, black, cylindrical pumps mounted to the lower wall in the engine room.... Who made them? What are good replacement pumps for this application? stock 525sc's for the most part....
thanks!

I think the stock pumps back then were Stewart Warner. I've had great luck with the Holley "Black" pumps.

so, in looking at the holley blue and black pumps.... they are rated in GPH.... I dont know what mine are. I know I am at about 7.5 - 8.0 PSI at the carbs, but what flow rate do mymotors need? they are 502's with TBS 250's making 5 lbs of boost. Thanks.

-The Black pump will work fine for your application. The Blue pump has had reliability issues.

cool, so no regulator needed? this will be a direct swap for my factory pumps? thanks gus

I would run the regulators...

Yup, the black pump requires a regulator but I'm pretty sure it comes with the pump.

Thanks fellas, I appreciate the info!

yep, go with the holley blue or black pumps they do come with the regulators. (use them) when you notice they are getting louder replace them right away dont wait for them to burn out. greg

I looked real closely at the fuel pumps that are in there.
They say Walbro on top of them. I cant make out any of the writing or engraving on the sides of them though. Judging by the looks of the rigging, I am assuming they are the stock / original pumps. Anyone know anything about these? What flow rate they have? Model #, etc? Just want to pin down exactly what I have in the boat now. Thanks.
