Hi,

I need to install an in-line fuel pump for my nitrous kit.

The instructions are pretty straight-forward. The part that I'm concerned about is this:

"Cut-out a section of the vehicle's steel fuel delivery line. Debur the cut ends and remember to remove any metal shavings that have accumulated in the fuel lines..."

My question is, how exactly do I go about doing this? What tool do I need to cut into our fuel lines, and do I need to worry about sparks starting a fire? Is there an easier way?

Thanks in advance,

Matt

Be sure your tank is empty for one thing. You should cut the metal lines to do your install since the only other choice is the plastic lines and they're harder to terminate and get a good seal.

You should remove the line at the fuel rail and disconnect the fuel filter. You could use a compressor to blow the fuel backwards out the filter end of the line. If you cut the fuel line with a tubing cutter, you will get the best cut. Be sure to check if you need to flare the tubing after you cut it.

I just installed the Aeromotive fuel pump after removing the intank unit. Sumped the tank and used braided fuel line and removed all the old fuel lines. I will install the 383 next year and need more flow but won't be using giggle gas.

Any more questions email me at jamianddave@juno.com

good luck

 

NOS has instructions and parts list in the 5176 kit for tying in an inline fuel pump without cutting any lines. They pull the pinch clamp line off the inlet of the fuel filter, add a "pinch clamp-to-barbed hose" connection, with double clamps, and complete the install with reinforced high pressure fuel hose and clamps... no cutting.

If you are interested in a copy of the install instructions, e-mail me your fax #.

 

Where might one find one of these "pinch clamp to barbed end fittings?" PLEASE tell me at Kragens. Also, does anyone know the sizes of the fuel lines offhand? I'm putting in an MSD inline pump today.

Thanks,
Chris

 

go to www.vortechsuperchargers.com, in the install manual for 93-97 fbody they have instructions for installing the T-rex. The directions were pretty good and there was no cutting of metal lines involved, I would not want to do that.

 

I did end up cutting the metal line, was easier that way, and makes future fuel filter changes "normal." I also didn't want unfiltered fuel hitting my new MSD pump.

BTW, after the install of the inline and a new filter, the car runs TONS smoother, and no 300/302 codes anymore. No word yet on more power (it's like 94* here right now) but as soon as I get my replacement 6AL in I'll be ready to hit the juice.

 

what happens when you want to take the inline out??? now ur screwed. when mine needs to come out i just unscrew one fitting and screw it into another.

 

Not really a good idea to put the inline pump after the filter. Too fine a filter element could help starve the inlet side of the pump. The supply side is already adequately protected for the clearances in the pump by the sock on the intank pump. When you protect a pump with a suction side filter, you use a much coarser filter than you would use on the discharge side to protect the injectors.

NOS part # 15007-S, 1/2" hose barb x "GM" fitting. No cutting required. My NOS (Bosch) inline pump ran for 5 years in that configuration, and is still being used as an outboard/parallel pump in my current nitrous system. Going on 8 years of use.

 

if I need to remove the inline, I can splice in a piece of aluminum 3/8 fuel line, or rubber fuel line. How can that POSSIBLY be a big deal to you? As I said earlier, now the inline is after the fuel filter, so not only does it get clean gas, it now gets to compensate for any pressure or volume drop caused by the filter.
