will this cause my fuel pump to die an early death

[rfalker1]

SO I have an issue and I am not sure how bad. Basically my 68 camaro .. twin turbo and I am swapping out my fuel system to go bigger and fuel my fast refi 2.0 throttle bod. However in doing so I was required to get a bigger pump and thus bigger houses.

So I bought a Holley 12-1600 fuel pump, the lines and all the fittings but then when we opened up the tank we found out the sending unit is only 1/2 inch (basically) -8an and has to stay in the length for 8 to 10 inches.

I don't have any other options besides trying to get a smaller pump, which would kill the amount of power i can make or go with some type of full cell. This is just a normal car. no racing. just some random drives. Wanted to know how big of an issue do i have or will I be okay. The guy makes one with 10an fittings so it must not be that terrible since its an option. But I wanted other opinions. I have talked to one person at holley and they said it would be fine and another that was like I was going to kill everything from doing it.

Thanks for any advice

I think this warning on the Holley website pretty much says it all:

This pump is not designed to use a standard conical seat style union in the inlet or outlet of the pump. Example: Part # AT981510ERL. Use of this style fitting will block flow and WILL lead to poor performance and pump failure. The ONLY correct fitting to use is a contoured port fitting with an O-ring seal such as :Part # AT985010ERL.

In other words use of a -10AN fitting to connect to the pump instead of a -10 o-ring will lead to poor performance and pump failure. Presumably a -8 AN fitting will be even worse.

28 amp current consumption? That is an awesome fuel heater and I can’t see it working out on a street driven car.

1600 hp capable. How many do you have?

Are you planning to run the two pumps sequentially? I think you should to reduce fuel heating....

No I was just planning to run that one giant fuel pump. Its basically already installed. So Is there a pump I can run from this that would work out. I seems I am at a stalling point.. this sucks

found a magna fuel pump that is set for a -8an line! Will run that instead! Thank you so much for your response. You changed my direction of thinking and saved me a lot of money!
