As part of my EFI conversion I installed a Fram Twist-on between valve and
fuelpump.

Great! How and how long did you burp it?

I am in need of replacing the fuel lines in my 76 Eleganza II

In doing so, how much does one have to raise the coach in order to drop the
tanks

Floor jacks, Jack stands, hd ramps???

Please advise as to the best way to accomplish this

I have fuel coming out on fill up

I have replaced the fuel lines from the switching valve (mid coach) up to
fuel pump and the steel line to the carb

However, I need to drop the tanks and finish the job

Am interested in how you got the coach up high enough to remove the tanks
with 6 each 1x8x6's. Where did you put them, under the wheels or the casting?

>I had the motorhome on six 1x8x6", under the boggies and the front on car

>Had the power steering lines made here locally. Had them replace the steel

>Bought a RIDGID flaring tool from Grainger and a 20' long 5/16 ss tubing from
