Fuel Problems!! ej25 71 super...

New to the forums after reading a wealth of info on the site. Heres my problem. Ive had everything setup and had my car running already. the car starts and idles fine. but if i hit the throttle too quick, the engine chokes. then back to a normal idle. if i roll slowly on the throttle it runs normal. soooo... i drove it around the corner and onto a straight street, floored it WOT through 2nd and third. as wonderful as it felt, the car just would start choking under any kind of load after that. all the way back to my drive way. i could barely get it up the driveway cause the motor was bogging and choking. i checked all my lines-no kinks anywhere. im using aluminum 5/16" lines to the motor from a walbro 255 pump. i have a 1/2" output on the tank and 1/2" hose to a surge tank. then 5/16" to the efi pump from the surge. the pump turns on normally as it should and doesnt sound to be struggling. but when i got back from my drive i could hear some slight choking coming from it. quick question - is there a huge difference between the intank pumps and in-line pumps? can they both be interchanged? i modified the intank pump inlet with a 5/16" barb to use the pump out of tank...is this bad? it seems like my system chokes out when pushing the throttle too quickly. so my only thoughts are that i have a bad pump or i need a charge pump, like a facet. any thoughts? some extra info- ecu is a Stinger 4424 aftermarket ems.(map provided by outback) -no exhaust (only primary pipes-extremely loud!!) -no air filter while testing(too much air???) -replaced t-stat with open ring from outback(rad fans arent coming on at all for some reason?) ive attached some pics of my project i didnt know what that plug on the bottom of the tank was for, so i used it to plumb a new 1/2" barb.

Hi

A lot people who fit Subaru motors move the transmission forward by reversing the cradle under the bell housing.

car forums. where a lot of peoples good intentions end up taking a good old car off the road forever never ever to see the road again. 🥲

wow thats pretty clean. i was thinking of doing this to my car but wondered about where the nose cone mount would go since there would be no more room for it. i would have also had to modify the shit coupler length. i didnt mind cuttin it up. its def not nice to look at. but that doesnt matter when im 3 cars ahead of those hondas and v8's!! ill be covering up the poor cuts with strips of zinc sheet metal.
will be putting up pics of my exhaust setup when i can
