fuel filter fittings

[George M. Dailey]

Early musicions used to say electronic keyboards were an abomination. We
routinely use compression fittings on sample systems with 4,000psi of
pressure at 1,000F. They have worked for us for well over 20 years.
Compression fittings work and they work very well. I'm not sure what your
fuel pressure was (may have exceeded our pressures/temps), but I've used the
cheap brass type on my dailey driver and have never had a failure or leak.
Sure, it aint as jazzy sounding as double flaring tubing but it is neat,
quick, and proven to be very reliable. The only negative draw back is cost.
The double flare is much cheaper. 

As far as perfect instalation goes, they are a lot easier to use than duoble
flaring tools. My 10 year old could install one first time from verbal
instructions alone. Don't try that with double flaring. You've got to cut it
straight, de-burr and camfer, form the buldge from just the right length or
tubing, and then switch dies for the final flare. Damn....I made a perfect
flare and forgot to put the nut on the tube! I'm sure all double flarers can
relate to this one.

With compression fittings, you just clean the tube end and tighten um up.

And now Jim, I'm going to release the safety on this flame thrower
real....easy ;)
