Aftermarket Fuel Line options

Black97civic · 08-04-2005

I am going to be upgrading my conquest to multi-port fuel injection eventually, and now that I am replacing the fuel pump, and need to fix part of the fuel line, I am planning on upgrading, something that is definately recommend for starquests.

Anyway, I am wondering what kinds of aftermarket fuel lines you guys have used, and what you thought of them.

I am looking at a braided stainless line right now, as I don't know about many other options, and I have seen many cars with them.

My HP goals are fairly modest, somewhere in the neighborhood of 300-400hp, and the fuel pump I am going with can supply enough fuel, so no worries there, I am just wondering about my options for fuel lines.

You'll need either -6an or -8an braided line and a fuel rail, stock DSM would work. You'll also need to tap some hole in your manifold for injectors and fab up some mounting holes for the fuel rail. I'm not sure what the Starquests had back then but you'll also need a return line to the tank, -6an is more than adequate for this. Don't forget to put an inline filter before the rail.

There are other types of line besides braided SS line that you could use. I have only used SS braided lines, because they are shiney and I like shiney objects. -6 will be more than big enough for the feed line. Hell, -4 might be big enough for a Starquest.

I am going to be running the feed line and getting something made so it will go to the stock fuel filter for now, the multi port is still a ways off. I just don't want to spend money fixing the stock line, then take that off to replace it with the bigger line next year, or whenever the MPI happens.

As far as the return line, I guess they are big enough stock to handle pretty much anything until you start getting really extreme, but there can be problems with the capacity of the feed line when you go from 2 injectors to 4.

That is also one of the major draws for me. Braided stainless is cool, and this thing isn't going to be a sleeper, so it's not like I am hiding anything.

What size would you recommend for running 650cc or similar sized injectors??

**Shane@DBPerformance** · 08-04-2005

-6 up to 600whp or so.

Braided line is always cool. Expensive, but cool.

What would you guys recommend for a fuel filter.

I am looking to replace the one in the engine bay, which is about the size of an oil filter (i dunno what it would compare to on a DSM for sure)

There are a lot of filters that are similar on JEG's but I don't know which ones are good, and I can't really find any with -6 inlet/outlet.

This ahs to be a high pressure filter too, if they aren't all that anyway.

Yea, they aren't all high pressure fulters. I run an Aeroquip filter, but I think I had to get adapters for it, since it's a -10.

Do you think it would be possible to tell me a model number, or something along those lines??

If not, thats cool, maybe just a general idea of what filter it is.

BTW, this is Blue89quest, I'm just over at Andy's house.

Sorry, I meant Aeromotive, not Aeroquip. #12301

Some of those smaller aluminum fuel filters that you might find with -6 fittings on them by companies like Edelbrock, Earls, Russell, etc aren't meant to handle the fuel pressures you might see on a high boost car. If you aren't going to run 30+psi then you might be able to run one of them if you keep your base fuel pressure down at a normal level.
