View Full Version : For those with aftermarket FPR's, or who are making any changes to your fuel lines

Just a friendly reminder to always double and triple check your work. Simply turn the ignition to the on position to get the fuel pump going, then check your setup with a fine tooth comb *before* starting the car and introducing spark.

Then, check again. And one more time. Then start it, and check again.

Also, for any and all of us, these images may encourage you to purchase an appropriate fire extinguisher and fire blanket to carry in car at all times, and take this advice to heart.

If this were my car I would be heartbroken.

I would also like to point out some products that ARE NOT GOOD ENOUGH to do the job.

I recently purchased some SS braided hose and fittings from siliconeintakes.com, mainly because it was cheap and I figured I could use some extra to have on hand.


Although the site goes to great lengths to explain how great they are - I would beg to differ.

The quality was horrendous, the fit was extremely poor, and I couldn't get the damn line/fitting to seal for the life of me. I compared the fittings side by side with Earl's fittings that I had, and the differences were so obvious that I had no choice but to toss the siliconeintakes crap in the trash.

Please don't use that stuff.

Fuel is not the place to be cheaping out...

That car did belong to one of the members (brandontoyota) at Alltrac.net. He'd just got done dumping a lot of cash into and had installed a CT27 about a week earlier. From what he said, it looks like something went wrong either with the AEM FPR or the install. Either way, it torched the car completely and melted most of the engine parts. Tough way to spend your Thanksgiving.

And on top of all of this, it was one of the 81 1993 models.

I guess this would be a good time to ask then. Is it ok to have a brass fitting in your fuel filter to rail line? I did it to check the fuel pressure a long time ago and haven't seemed to have any problems.

Something similar happened to a friend of mine who's cold start injector hose broke and he decided to ghetto rig a fix. I told him not to chance it and it replace it with an oem line but he didn't listen. It was fine for a month or so until one day it burst and the car caught fire. He got super lucky as someone just happened to pull over with a huge extinguisher and helped him put out the fire.

That sucks man. -1 alltrac.

Amen, skimping on the fuel system in ANY way is a recipe for disaster. :ohnoes:

I don't see brass as an issue - although I'm not 100% certain if reacts with fuel...I don't think so. Isn't there some brass fittings oem? I have no idea, it's been a while.

Yes, brass fittings can be used in fuel line setups, but only fittings and if you can get chrome-plated brass fitting, thats even better.

It's a sad thing to lose a car. But it sounds like everyone made it out with their lives, and that is infinately more important.

As a side note, don't certain racing classes require vehicles to have fire suppression systems built in? I seem to recall hearing about needing a big red button on the dash near the drivers door (easy access to driver and anybody outside car on drivers side) that would both cut all the electronics and douse the engine bay and cabin with fire extinguishing foam. I think the kits are worth about $400 and up. These stories make me wonder why more people (myself included) aren't putting these in. Hell, considering how dangerous car fires are these should be stock!

Back on topic. You can not be too safe when dealing with fuel systems. Like Chris said, check your work over several times. Then have a fresh set of eyes check it over.

Thanks for the reassurance guys. Done threadjacking now. Yeah, saw that on AT.net also. Actually kinda made me queezy.

When you buy AN fittings for your fuel setup, you will notice that it states it is only compatible with certain hose. Sure, it will work with other hose, but it was designed to work with a certain hose. You should be fine if you stick within the same manufacturer.

If you so buy an extinguisher, get one that is B and C rated for liquid and electrical fires.

^ Fittings themselves are interchangeable so long as they have the same flare. JIC/AN fittings are all 37*. SAE are 45*.

The problem is with hose ends and you don't necessarily have to stay within a manufacturer. It's more important that stay within a certain type of hose.

For instance, Earls makes a kevlar hose with PTFE lining, speedflex with ptfe lining, and super stock hose that is incompatible with their autofit/ano-tuff/swivel hose ends which are meant for cutter-type hoses like their stainless/nylon braided hoses with rubber lining.

But Earls prolite 350 is essentially the same thing as Jegs proflo 350, et cetera. So hose ends for those would be interchangeable.

But you can mix and match fittings all you want as long as they seal the same way.

That's what I meant.
