First things first:So at idle I have 18psi. At wot it drops to 3psi. Sometimes at idle it has only 7 and then will just back to 18 after a few. Could it be that I streched out the pressure spring or could need a new one. Thanks for the help
Man....double check that sending unit.....been down this road with them several times.I have the 150. I have the pressure in the additude monitor and I cant find any leaks. The filters are new. Whats the bucket test, how do I check the in-tank pickup, and where I get a new spring because this seemed to happen at around the same time I played with the spring. Thanks for all the help Dan
That's Correct, you can use the FASS to load and Unload the test bucket as well.Just so im straight on this the return goes to the filler neck and the suction goes to the tank correct and also do you have any online dealers. Thanks alot
OK.....i still like to always see a mechanical gauge used to test for pressure in these situations when troubleshooting a electric gauge. Just good practice.2001 24 valve,my 95 pump only runs 14/15 at idle but drops fast to 8/10psi on light throttle up and 0/2psi wide open.:CRY:I tried a different sending unit same.I was wondering if I went to a 1/2" line fump to filter instead of the 3/8" it came with? I would like a stronger spring just to try or do I need a 150 pump?I use a WS 1001 stand alone for a pre strainer.
Its internal and not servicable unless you cut the wire. This is not really an issue unless you got real crazy with the teflon tape or didnt use our prestrainer. That is about the only time I see issue with debris that causes pressure probs.Pump is 6 months old,I do not have the SN handy. I think I will blow back the siphon to see if it's strainer is partially restricted.Where is the bypass located in this pump?
Have you tried the 5 gallon bucket test yet or sucking out of a jar of fuel?Well used high pressure to backflush the siphon tube and still no luck.If you have it in neutral with the box on #3 stick it to the floor real quick & let off 10 psi is what it drops to.opcorn:
Most likely your gauge set up..... have you checked it?I just installed a fass 150 4 weeks ago pressure was reading 16 all the time with a 1 to 2 psi drop when i hogged on it and now it is reading 5 all the time. What might be the problem? it didnt drop all together, it dropped like 2 1/2 psi per day. Now steady at 5. Please help.:CRY:
