Don't use the in-tank electric pump.

along with my afpr i bought a holly blue inlne fuel pump...so i was just gonna pull the intank pump runa hose into it, dial in the pump and dial in the regulator...but i was reading the sticky for the 10th time about doing efi to carb and says i NEED a return style

i am pretty sure you will need a return style FPR for the holley pump... a hose into the tank isnt a very good idea... if you wanted it would probably be easier to go pick up a tank from a carbed 3rd gen then dealing with your current one

easier to deal with...harder to find, i dont see a problem with he non return afpr all its going to do is restrict unneeded fuel instead of free flow it through and back to the tank?? sort of dead head but not complete right?

SpitotRs305

well it will pretty much be a dead head with the carb and will burn that pump out.... early.. unless it has its own pressure switch

You can use a non-return style AFPR. I have used it on my other firebird for a year. I do not recommend it, makes the temperature in the pump go up. Therefore decreasing the life of the pump.

So.. $80 for a AFPR return style? Or $100 for a new pump and the amount of time it takes to drop the tank?

very good point nelapse its about time someone just gave me the blunt facts. i just dont understand...why would they even offer an non return fuel regulator if it lessens the life of a pump? is this simply to increase product demand? or just a cheaper way of getting your goal complete such as swapping to carb? SO..what your saying is start looking for another regulator return style and ditch the non return regulator. great thanks. ALSO another question for someone who's done the efi to carb swap....how exaclty do you do he intank pump mod in order to accept the new inline pump? i know, drop tank and pull it out and put a hose on it??that sounds too...idk simple

check the carb board they have pictures of the most effective in tank pickup

Every fuel pump is different. Some inline pumps that are external to the fuel tanks do not require a return style. You can buy those pumps all day long. They are everywhere, and those are okay to use the 2 port regulators.

Another reason people use two port regs is because they have dual carbs and they use he 2 port as a secondary regulator.

If you used a 2 port on your pump I am sure it would last a few years, just know that you will not get 100k miles out of it, but if you were to use it to get you by then by all means.

Also, what inline mod are you talking about? Just installing an inline external pump?

I drew this up for someone a while back, maybe it could help.


Just make sure you remove the inline pump from the tank if you plan on using an external pump or else you will vapor lock the intank one.

im planning on using my holly blue fuel pump inline to run into my fpr and then to carb. im not sure how to mod the intank fuel pump ***. to accept the new modification. i am not sure what the specs. are on this pump its prolly just a standard pump w/o pressure switch.
