Fuel pump help
Hi all,
* I unfortunately have a fuel leak on the Proflow fitting on the exit of the second fuel filter (after the twin GS342 Walbro pumps). * If I disconnect the fuel line to replace the fitting am I going to have to contend with a 68 litre fuel flood all over my workshop floor, or will the (switched off) pumps stop the flow from the freshly-filled fuel tank and all I'll lose is the minimal quantity of what's in the lines and filter? If the former，how does one go about changing the fitting without draining the fuel tank? Thanks in advance for any assistance. Sime |
Get yourself a cheap siphon pump and empty the tank.
3in1 Siphon Water CAR AIR OIL Pump Extractor Liquid Fuel Transfer Inflator Hand | eBay I put a fuel drain bung in my tank when I built it for this sort of occurrence. Cheers |
This is one reason I decided to put in an above tank surge tank.

just clamp off the rubber fuel line super cheap sell cheap clamps that work well on rubber fuel lines

I agree with whoever said to siphon the tank. It's easy.

Jam a piece of shaved dowel into the fuel line or plastic dowel, may get a couple of drips but should stop you having to empty the tank. Did this with my Prado and it holds 180 litres!

Thanks for all the suggestions ;)
Before I went to the trouble of siphoning the tank, I thought I'd try and loosen the fitting to see how much fuel I'd potentially lose (had a 6 litre drain pan underneath to catch anything) and surprisingly, only lost about 15ml. It appears that the fuel pumps do indeed have a check valve inside them because there is no fuel flow when the motor is off. |
Anyone else had this problem?
I can't get my pro flow fittings to seal well on either side of both filters. Just one drip each week. I wondered whether anyone had just replaced the filters with another brand and what they used. |
Turns out that my leak is not from the line，rather it is the Proflow fitting on the end of the fuel filter. I'm going to change it out and see if that fixes my issue.
