Inline electric fuel pumps
I'm looking for a low pressure inline electric pump for my TBI 350 Chevy to Holley carb conversion. On the Hotrodders Forum they recommend Carter P4070 for converting from mechanical to an electric pump (on a carbed engine). When I messaged Carter they recommended P4070 or P74019. Has anyone here used either of these inline pumps or have any other suggestions? Carter said with both of these pumps I would need a pressure regulator and a fuel return line.
Thanks.

I've run the Mr Gasket (42s I think) for years behind a mild smallblock with a holley street avenger carb. Has worked like a champ.

I've no experience with the Carter pumps. My go to is the old Holley Blue pump. It works very well combined with a bypass carb specific regulator but it's a noisy little bugger.
It's mounted where an EFI filter is located with a pre filter in the wheel arch and a post regulator filter at the carb.

I went ahead and jumped the gun and ordered the Carter P74019. It has a one bolt strap mount, so I'm going to try to bolt it to where fuel/brake line bracket is on the left rear subframe rail where it starts to go up in back of the axle housing. That way it's within the two feet o f the tank Carter said it needed to be and as low as possible. I believe you get a filter to put in front of the pump with the kit so I'm planning to do away with the factory filter under the car. I may add a filter in front of the carb just for grins, but I don't know is it's necessary.
The two fuel/brake line clips holding the lines to the rear subframe rail sure were a pain to get off. I ended up breaking one in the process. I suppose it's good luck finding a new replacement for these oddball clips. I've come to the conclusion that these cars weren't made to be worked on.

A 100 micron pre-pump filter is typically recommended.
Another filter before the carb at 10 microns is the other standard.

Re: Inline electric fuel pumps
really! I feel like mine was made to be worked on, like all the time. I hear it calling from the garage sometimes. And yeah, once everything has been removed and replaced it's easy to work on.
Except the gas tank! I can have the rear and all the stuff off around the tank in an hour and wrestle that tank and curse at it the whole time. Getting it in definitely had more cursing than out.

Oh, I know all too well. I'd rather do a trans or engine over that again!

Re: Inline electric fuel pumps
I wonder why GM didn't just stick with the filler neck coming out the back in front of the license plate like on 2nd gen F-bodies. It would have been a lot cleaner look, too, than having a plastic gas filler door in the middle of the quarter panel like our cars got stuck with.
Were any 3rd gen F-bodies made with metal gas filler doors? It would be nice to have a metal one.

Because of the Rear-Glass design/ Latch Location...
