Engine/Transmission (1998.5 - 2002) Less than 1/4 tank = Hard Start

[smokinhole]

After installing the GFS pump kit I have been having trouble with hard starts when my fuel gets down below a 1/4 tank. I've never had a problem before and didn't touch the plumbing back there at all. It's wierd, I can go put a couple gallons in and voila all is good again. What's the deal?

Fuel tank module? Sorry, I'm not sure what that is. If you are referring to the in tank pump setup. I never had one, my pusher was still mounted up front. This is a common problem?



So what would fix this cheaply? I'm sick of throwing money at my fuel system.



Thanks,

There is a module in your fuel tank which houses the fuel sending unit, pickup, return and filter screens. This is what needs modifying. A Vulcan Draw Straw will solve the problem, it is reasonabley priced and fairly easy to install.

Eliminatnig some of the restriction associated with the stock fuel tank module is a great idea, but be aware that although it is not technically difficult to drop the fuel tank, some small pesky things can get in the way such as gettign the forward strap off so that the tank drops cleanly, etc. It is not an insignificant job and you should allow a full day for it, just in case. Heck, if I did it a 2nd time, it would probably take me half the time, but I am an engineer and try to work by the "measure twice and cut once" philosophy, so it took me a while to get it done.



I installed the FASS High Performance Fuel Pump (HPFP) at the same time as the draw straw, so cannot comment on individual advantage(s) of each, but there is a remarkable improvement in fuel pressure since I have done the work.

Aaron A,



Thanks a bunch for that link. I think I understand whats going on now. I was having a hard time wrapping my head around what was going on in the tank. I didn't know there was anything in there but a simple fuel pickup.



Thanks!

Here's a thread from a couple of months back on the Draw Straw and the fuel pickup module.
