Can anyone tell me how much hse i need to get from where i hook up to the fuel source to inside the cab? I was thinking of getting one of the mounts that goes where the cubby hole is under the passenger airbag switch.I am not going to use an isolator either if this helps any.

check out http://www.dieselmanor.com/ they have what you need

That is where I am looking at but I dont know if I need two 36'' pcs. or something else also I was hoping someone would chime in with a cheaper solution to the fuel line than diesel manor has. I like the idea of the braided line but it is a little on the high side i was wondering if there was something just as good but maybe a little less expensive.

anyone else?

I used 6 feet of steel brad I bought it at http://www.egauges.com/ they had the best price for it. I mounted my gauge on the a-pillar 6feet is about 1 foot longer than needed but the 4 foot would have been to short they sell 3,4 and 6 foot lines.

I mounted my fuel press gage under the dash right above the accel pedal. I oredered a 4 ft peice of -4 an, and had a 1 1/2 ft piece made locally. That gave me enough to run from my engine to the drivers side fender, where I have my needle valve, and then from there to the gage, with enough extra to not have any of the lines tight against anything.

6 ft will be most likely more than enough, but better to have too much then too little.

if you can find a place that will make you up the line with re-useable fittings, you can make it the exact length you need yourself.

Thanks guys. This helps alot

I've been using the same type of 1/8" tubing used for boost gauges for over ten years without a problem. Just push it though some larger tubing to create a protective sheath. You can buy 1/8" air brake tubing and fittings at any auto parts or use a hook up kit for a mechanical oil pressure gauge. Either way will cost you around $10.
Braided line is a way overkill for a measly 15 psi.
Besides that vibration tends to cause braided line to saw though anything it touches creating further problems over time.

I used 1/8" copper tubing and have had no problems. I have about 18" of fuel hose from the VP44 to the tubing to soak up engine vibrations. The small ID of the tubing also seems to dampen out the pump pulsations before they get to the gauge.

TRCM

I chose to go with better hose because I have had the nylon & copper break with age on vehicles which had way less vibration.

and My gage says 25-30 psi....not no 15....LOL.

Mine says 35-40 since it's a 12 valve

I used 1/8" plastic tubing for FP and boost on my trucks the first month after I bought them new in late '94.
Still using the original 11 year old tubing.
Copper tubing is more prone to fail though, flexing doesn't agree with it.

TRCM

let me rephrase that...I've had the copper break from fatigue (vibration) and the nylon got hard from heat and cracked.

how the heck did you get 35-40 psi ? I shimmed my OFV to get what I have now.

I used 7' of 300 psi rated hydraulic hose from NAPA. Didn't cost much, and should last since I don't think I'll ever see 300psi going through it That lenght left me enough to pull the whole pod off the pillar with the gauges in place if I need to for bulb change or whatever....I may have even shortened it a bit, can't remember.

I've got my copper tubing tied down pretty good to eliminate flexing. I've also used this tubing on my Jeep's oil pressure gauge for 20 years now with no failures and I know there's much more vibration and flexing in that application.

I'm using Marty's OF valves, they are 28 at idle instead of the stock 24 psi.
I usually cruise at 35 but on a downhill will peak at 40.
