94 Civic Si

I have a '94 Civic Si w/ a B18C1 swap.

The fuel line from the filter to the injector rail looks a little short/tight - see pictures.

Does anyone know which line is longer - Civic or Integra?

Or is there a recommended fuel line for going from filter to the rail in this swap?

Thanks all!

With both ends tight... bend the hard line slightly toward each other and there will not be that stretched look that concerns you. There will be no flow related issues as long as you don't kink it from bending way too much.

I had not thought of that - thank you!

If no one has any comment about how long the 2 different hoses are (Integra vs. Civic), then I will do this.

I had a similar problem
y7 97dx
jdm high comp b20
used og y7 fuel line
was just short by 1-3 inches
also had to bend the alignment pieces out

What I did cuz I didn't wanna bend the actual fuel lines
the fuel filter is held by 3 10mm Iirc
i took out 2 of them
bent the fuel filter mount out further a bit
held the filter mount with one 10mm
works fine for me

Hopefully you can imagine what I was describing ^

I can! You re-oriented the fuel filter to get a better reach out of the line, eh?

Thanks!

One last question - did you get a chance to compare the B20 fuel line to the Y7 line to see which one was longer?

I can't say for sure yet because my C1 is still sitting on a pallet, but there is a difference in the two fuel line.

First, you'll notice that your fuel filter is fed from the top and the fuel line comes out the top and down at a 90* angle.

On the Integra, and later model year Civics, the fuel is fed in from the bottom and the fuel line comes out of the filter at a 45*ish angle.

With our type of fuel filter, I'm hoping, the fuel line with the 45*ish bend will create some slack.

You cannot use a Y7 fuel line with a stock "B" series fuel rail if the rail has a fuel pulse dampener on the inlet side. The appropriate fuel line choices are from a '92-95 Civic EX/Si OR a '94-01 Integra (any engine).

If you want a longer line, purchase a Russell Integra fuel line... it is longer than a stock line and looks nice too. Part number is 641120.

Thanks all. I will check out the Integra fuel line - stock or Russell.

Best bet is always to start with the line from the chassis the engine came from. There are very few circumstances where that won't get you the right one.
