Questions for under bed gas tank guys....

[SCOTI]

Those of you that moved the tank under the bed, can I get some follow-up info on the job?
What kind of tank did you use?
How did you route the fill line?
What size fill line?
Any problems w/modern pumps 'shutting off' during the fuel fill process?

I removed the in cab tank for a blazer unit under the floor. I've routed the OE 2.25" neck to 2" line to the tank w/one 90° bend (2" 90° pipe) to the tank inlet (enlarged to 2"). The fill line which is approx 22" currently only has < 5° of slope so I'm concerned the gas from these 'environmentally friendly' gas pumps is going to constantly shut the freakin pump off which is something I hate dealing w/on my 74.

I did some Googling on the subject last night & didn't like all the issues I came across. Not just old cars (very common issue after searching through the HAMB) but new cars as well (late model Mustangs & Vettes seem to have more than their share of PO'd owners).

I really don't want to have this 'filling up' hassle w/a truck that gets driven daily. Your info could help me or possibly others make better choices when taking on this modification.... Thanks in advance!
