Fuel Pressure Hose

[JPittman]

I will be installing an electric fuel pressure gauge, running the hose from the banjo bolt post filter on top of the fuel canister ('99) to the sending unit. I have read posts that air should be left in the hose. I would think that if air is in there it will eventually get into the pump, etc. and I would have a "no-go" situation. After all when I change the fuel filter, I bleed the air from the test port so it will start. Wouldn't it be better to have that hose full of fuel to the sender or am I am just thinking too much?



Thanks in advance for the help.

I bled the air from mine before connecting the sender but when I changed the filter, I'm sure it got air back in there. Seemed like too much trouble to worry about it so I just long-cycled the lift pump 3 or 4 times. Started right up and no troubles since.

Don't worry......

alot of people do this and have never reported any problems.

I have a mechanical Autometer gauge which uses 4' of braided line, never bleed the line before the install and it works great. I don't think it's necessary to bleed the air from the line, but if it makes you feel more comfortable with the install, I can't see how it would hurt anything either. A few members have stated that they felt that leaving the air in the line may help to lessen the pulses to the sender. I'm not sure if that is correct, but I can tell ya that my mechanical gauge has a very smooth needle sweep. I plan on reversing my FP gauges when I change the next fuel filter, so that the mechanical is post filter and the SPA is pre filter. I'll leave the air in the line and see if it performs the same.
